Dr. Chittick's Love, AIDS, Sex and Teens Glossary and Dictionary

THE BEST, MOST EXTENSIVE, AND MOST HONEST GLOSSARY ON THE INTERNET

Currently the Executive Director of TeenAIDS-PeerCorps, Dr. John Chittick did his ground-breaking doctoral research at Harvard University investigating school AIDS programs and the coming wave of teen HIV/AIDS, before most experts had acknowledged the likelihood. One of his mentors was Dr. Jonathan Mann of Harvard’s School of Public Health who assisted Chittick in his early work in the field of AIDS prevention and youth vulnerability.

This glossary is provided to better understand current terminology regarding HIV/AIDS issues found in common usage, in the relevant literature, on this website, and among youth as well as professionals. Many medical and scientific terms are based on the publications of the Centers for Disease Control and Prevention, the World Health Organization and UNAIDS, Harvard's Global Policy on AIDS Coalition, National Library of Medicine and many other authoritative sources. Volunteers contributed their definitions; some suggestions were from their own experiences, relevant websites, and other sources (credits will be posted). Teen and modern slang terms come from MTV, VH1, BET, cable TV, movies, radio, and from interviews conducted by Dr. Chittick. His doctoral thesis (“Adolescents and AIDS: The Third Wave,” Harvard University, 1994) and contemporary research literature were also consulted.

Based on medical, psychological, educational, sexual, adolescent, sociological, and cultural terminology, this glossary should explain or illustrate about 95% of everything relating to adolescents, sex, drugs and AIDS (in a very broad sense). Teen talk, lingua franca, slang and some profanity (a few, so-called “swear” words) are also included for the obvious research reasons. Chittick has found in his extensive interactions with youth worldwide, that teens use terms among themselves that they don’t use around adult authority figures. Teens understand that many of the words they consider to be cool are considered vulgar by many grown-ups. They avoid confrontation by speaking one language with parents, and a different lingo with their peers. Adults who have overheard intimate teen conversations understand the truth of this observation.

From his Harvard days as President of the Student Association Council, Dr. Chittick has strongly opposed any censorship of research-related information. He believes that honest, medically accurate access to facts and terminology is necessary to best understand what is going on in the adolescent world of HIV/AIDS. A full comprehension of relevant terms better assists the researcher and educator, and that knowledge leads to more complete information and then, more effective prevention techniques.

Foreign visitors to this site and readers of English-language publications hear and read words they don’t know and can’t find in regular, abridged dictionaries and glossaries, leaving researchers and teens uninformed as to crucial data. TeenAIDS thanks the many sources that helped build this huge glossary for the serious researcher. Some early AIDS terms (pre-1985) that are no longer in common usage have been included.

For purposes of discussion, the term AIDS is commonly used to include HIV infection (the virus) and the diseases associated with AIDS and AIDS-related opportunistic infections and diseases. “HIV/AIDS” is also used specifically and generically.

(New terms are being added frequently. If you have suggestions to add or terminology to modify, please feel free to click here and your request will be personally reviewed by Dr. John himself.)

Note:
abbr. = abbreviation.
adj. = adjective.
a.k.a. = “also known as.”
alt. = alternative term.

A B C D E F G H I J K L M N O P Q R S T U V W X Y Z


A

AACTG (abbr. for Adult AIDS Clinical Trials Group): HIV clinical trial organization, largest in the world setting standards of care for HIV infection and opportunistic diseases related to HIV/AIDS.

AASECT (abbr. for American Association of Sex Educators, Counselors, and Therapists): Largest certifying body in the United States for sex therapists who have graduate degrees, with one or two years' post-graduate training in human sexuality.

ABCs of AIDS: Dr. John’s concise guide for youth to avoid HIV/AIDS: A = Abstinence; B = Be Faithful (monogamy); C = Condoms. Dr. John counsels that 1 or more of these choices can protect teens from HIV although no sex is the best way to avoid the sexual transmission of HIV. He also warns against any needle-sharing for drugs (including steroids), tattooing, and body piercings (most popular with teen girls).

ABO blood-type system: A blood-type system that consists of two basic antigens, A and B. Blood-type O is the absence of both antigens.

Abortion: The ending of a pregnancy and expulsion of the fetus from the uterus. This can occur either by induction or spontaneously (known as a miscarriage). The abortion procedure is politically, religiously, and socially controversial; it is legal in some places and prohibited elsewhere (see pro-choice and pro-life). Teen girls may have to get prior parental or court-approved permission to have an abortion.

Abortifacient: Any chemical agent that induces abortion.

Absolute CD4 count: Also called: T4 count -- the actual number of "helper" T-lymphocytes in a cubic millimeter of blood. The CD4 count declines as HIV infection progresses. It is frequently used to monitor the extent of immune suppression in HIV infected people.

Abstinence: To refrain from having sex of any kind. Teens are told many reasons why having sex when young is bad (emotional, physical and social problems). Although requiring strong self-control, youth who believe in abstinence must remain celibate until their wedding day (no exceptions are allowed including masturbation). This strict philosophy is supported by many religious organizations. Dr. John’s perspective is medically-based: “No sex = no AIDS,” and he adds, “if you don’t have sex you won’t get sexually-transmitted HIV. Other non-sexual transmission routes include needle-sharing, breast milk, and blood transfusions.”

Abstinence-based: A slightly more open curriculum that stresses abstinence as the safest way to avoid HIV but allows for limited discussion of some medical information dealing with specific sexual activity and AIDS prevention.

Abstinence-only: A strict morality-based educational philosophy that preaches "no" to any sexual activity before marriage (no matter how old or if partners are faithful). The program stresses that not having sex is the safest way to avoid the sexual transmission of HIV/AIDS. Dr. John counsels teens that abstinence is one component in an overall medical approach but should not be offered alone. When school districts offer one restrictive perspective only to students, they are censoring needed medical facts. If full life-saving information is absent, more teens will contract HIV/AIDS and die. Sometimes referred to as “Ignorance-Only Education” by AIDS educators because studies show no evidence that abstinence-only education reduces the rate of teen pregnancy or sexually transmitted infections including HIV. Studies suggest that adolescent sexual activity may actually be greater among students in these programs who are denied the complete medical facts (and they are at greater risk when they don't use condoms).

Abstract: A written summary of the important points of a scientific article.

Accreditation systems: Monitoring system in which outside inspectors periodically visit a service site and determine whether its performance meets preset standards (these can be for education and medical organizations).

Acculturation: The process of adapting to a society by incorporating the beliefs, behaviors and customs of that culture.

AC/DC: Bisexual; a person who engages in both heterosexual and homosexual activity (slang: swinger).

Acquaintance rape: Date rape; sexual intercourse coerced by someone known to the victim.

Acquired immunity: Resistance resulting from previous exposure to an infectious agent or antigen, may be passive or active. Passive immunity can be acquired from the transfer of antibodies from another person either from mother to fetus or via breast milk; also by inoculation (vaccination).

Acquired Immunodeficiency Syndrome (AIDS): A progressive weakening of the immune system accompanied by one or more indicator diseases (or opportunistic infections) including Kaposi's sarcoma, invasive cervical cancer, Pneumocystis Carinii Pneumonia (PCP), and wasting syndrome. With AIDS, deterioration of the immune system is marked by a depletion of T-helper (T 4/CD4) cells, which help stimulate antibody production. AIDS is commonly accepted to be caused by the retrovirus, HIV. The Centers for Disease Control and Prevention (CDC) lists numerous opportunistic infections that in the presence of HIV infection constitute an AlDS diagnosis. In addition, a CD4 count below 200/mm3 in the presence of HIV infection constitutes an AIDS diagnosis.

Acrosomal reaction: The release of enzymes from a sperm's acrosome.

Acrosome: The covering of the head of the sperm that contains enzymes that allow it to penetrate the ovum.

ACTIS: Abbr., AIDS Clinical Trials Information Service.

Active: The role of the aggressive sexual partner (usually the “top” or insertor) as compared to “passive” role.

Active immunity: Immunity produced by the body in response to stimulation by a disease-causing organism or other agent. The protection can be a result of being exposed to or having the disease or from a vaccine to prevent getting the disease.

Active immunization: A process by which a person is inoculated with an antigen to encourage their immune system to mount an immune response, e.g., by producing antibodies. Contrast with passive immunization.

Actual failure rate: The average failure rate of a contraceptive. This takes into account not only failure of the contraceptive, but also human error and non-use.

ACTU (abbr. for AIDS Clinical Testing Unit): Clinical trial sites

Acute: Condition that is rapid in onset and is severe and life-threatening; the opposite of persistent or long-term.

Acute HIV infection: The period of rapid viral replication immediately following exposure to HIV when high levels of plasma HIV RNA can be documented. Following the primary infection, seroconversion occurs (HIV+), usually within an average of 3 weeks after transmission of HIV. Previously, HIV was thought to be relatively dormant during this phase.

Acute HIV Infection And Early Diseases Research Program (abbr. AIEDRP): A program funded by the National Institute of Allergy and Infectious Diseases (NIAID) focusing on innovative ways to study how HIV-1 causes disease in adults.

Acute Retroviral Syndrome: A combination of flu-like symptoms (e.g., fever, sore throat, skin rash, headache, nausea, muscle or joint pain) that accompanies primary (initial) HIV infection that occurs shortly after infection. ARS is due to a cellular immune response that takes place before the immune system has had time to produce antibodies.

Acyclovir (also Zovirax): An antiviral drug used in the treatment of herpes simplex virus 1 (HSV 1), herpes simplex virus 2 (HSV 2), and herpes zoster.

ADAP: AIDS Drugs Assistance Programs.

ADC (abbr.) AIDS Dementia Complex: Deterioration of intellectual faculties, often accompanied by emotional disturbance. When HIV is active in the brain’s central nervous system, it can cause dementia, even in those with high CD4 counts and low viral loads. Treatment usually involves an anti-HIV drug such as AZT, that is able to cross the blood-brain barrier.

Adenine: One of the purine nucleic acid bases that make up nucleotides, the building blocks of DNA and RNA. The antiviral drug ddI is a nucleoside analog associated with adenine.

Addiction: Any time a person continues to exhibit harmful or obsessive behavior, they are addicted. There are many types of addictions from sex to drugs, cigarettes and alcohol.

Adenopathy: Diseases like AIDS involving or causing enlargement of glandular tissues, especially one involving the lymph nodes.

Adherence: Extent to which a patient continues the mode of treatment or intervention as prescribed. While most HIV+ persons adhere to the agreed-upon treatments, some do not, causing increased health problems.

Adjuvant: Ingredient(s) added to a prescription that modifies the action of the principal ingredient. Used in some HIV therapies or for HIV vaccines.

Administration: Refers to how a drug or therapy is introduced into the body, for example, intravenous (needle) or oral (mouth) administration.

Adolescence: The transition between puberty and adulthood is also the stage in human that occurs from puberty to physical and sexual maturity, lasting from about ages 12 to 19 (there is some debate about the exact age range, but the teen years are commonly accepted for adolescence). There are numerous theories about the changes that occur during this stage of life, but one that is consistent is that this transitional period is one of the human’s most significant times of change and growth when teens make the transition to adulthood.

Adolescent female sexual swelling: Develops in the genitals when she is about eight to ten years of age. Initially these swellings are very small and appear as a slight enlargement of the lips of the vulva. During the following two years, they become slightly larger with each successive swelling and, at some point, usually during the second year of adolescence and a few months prior to first menstruation, suddenly become considerably larger.

Adolescent growth spurt: A rapid increase in stature and other dimensions of the body that occurs during adolescence/puberty.

Adolescent medicine: A sub-speciality of pediatric medicine with a focus on providing healthcare to adolescent patients (and treating medical teen problems) that is common during adolescence.

Adolescents: Youth, usually ages 12 to 19 but can vary by two or three years; the time in their lives when their bodies undergo their greatest sexual growth.

Adolescents at risk for mental health problems:
Teens are at greater risk for developing mental health problems when certain factors occur in their lives or environments. Factors include physical abuse, emotional abuse or neglect, harmful stress, discrimination, poverty, loss of a loved one, frequent relocation, alcohol and other drug use, trauma, and exposure to violence.

Adrenogenital syndrome: Also known as congenital adrenal hyperplasia. A genetic condition in which a female is born with genitals which look like a male's due to an abnormally functioning adrenal gland.

Adverse reaction: Side effects, adverse event. An unwanted effect caused by the administration of drugs that may be sudden or develop over time.

Adult: The period in an individual's life cycle after the eruption of the last permanent teeth, and when adolescence has passed.

Adult height: Approximately 15% to 20% of the final adult height is added during puberty.

Adultery: Sex between a married person and a person other than their spouse. Adultery is one of the main causes of divorce. In many societies, it merits strong disapproval and in a few regions, jail and the death penalty.

Adverse reaction: Patients in trials may have toxic reactions to experimental medicines. Many of the drugs used to fight HIV and AIDS cause adverse reactions in some people.

Aerosolized: A form of administration in which a drug, such as pentamidine, is turned into a fine spray by a nebulizer and inhaled.

AETC (abbr. AIDS Education And Training Centers): The Health Resources and Services Administration (HRSA) supervises the national AIDS Education and Training Centers (AETCs) program. A network of 15 regional centers, AETC conducts targeted, multidisciplinary HIV education and training programs for health care providers.

Affair: A love affair or sexual relationship that is usually illicit or secret.

Affective Disorder (Also known as mood disorder): A category of mental health problems that include depressive disorders.

Affected community: Persons living with HIV and AIDS and other individuals, including partners, friends, families, and advocates whose lives are directly influenced by HIV/AIDS and its physical, psychological, and sociological ramifications.

Afterglow: The good feeling experienced after sex, especially the feeling a woman has after an orgasm.

Afternoon delight: An afternoon sexual tryst.

Agammaglobulinemia: A nearly total absence of immunoglobulins resulting in the loss of ability to produce immune antibodies.

Age grade: A group of people of the same sex and approximately the same age who share a set of duties and privileges.

Age of consent: The age at which a young person is deemed legally capable of giving consent to sexual interactions. In many U.S. states, the age is 18, although when teens have consensual sex, it is rarely prosecuted (however, usually the poor are targeted). In other parts of the world, 16 is often the age of consent and can be as young as 14.

Age set: A group of people roughly the same age who pass through various age grades together.

AIDS: Is now the commonly-used term for Acquired Immunodeficiency Syndrome and also for HIV/AIDS. The World Health Organization(WHO) uses the term to "denote the entire health problem associated with HIV infection." AIDS is not simply one disease but many diseases that normally affect older people with deteriorating health as a result of failure of the immune system. It is widely accepted that AIDS diseases are caused by the virus known as HIV.

“AIDS Attacks:” Dr. John’s term for his direct street approach to deliver medically accurate information to surprised youth wherever they gather. During his Global Walks, he successfully tested this technique in multi-cultural settings on six continents. Videos and images from his unique outreach efforts on six continents are posted on the TeenAIDS-PeerCorps website: www.teenaids.org.

AIDS Clinical Trials Group (ACTG): A clinical trials network of over 50 medical centers, sponsored by the National Institute of Allergy and Infectious Disease, which conducts multicenter trials of treatments for HIV/AIDS and opportunistic infections. From available data, they assign a low, medium or high research priority.

AIDS-defining illness: According to the Centers for Disease Control's(CDC) definition of AIDS, it’s one of the serious illnesses that are found in HIV-positive individuals; also used as a basis for an AIDS diagnosis. Some examples of such illnesses are PCP, wasting syndrome and CMV retinitis.

AIDS Dementia Complex (ADC): (HIV-associated dementia or HAD). Infection of the brain by HIV resulting in the impairment of mental functioning, as well as changes in both mood and behavior.

AIDS research advisory committee (ARAC): A board that advises and makes recommendations to the Director of the National Institute of Allergy and Infectious Diseases on all aspects of HIV-related research, vaccine development, pathogenesis, and epidemiology.

AIDS-Related Complex (ARC): A term that’s no longer used to describe a variety of symptoms in some persons infected with HIV that included recurrent fevers, unexplained weight loss, swollen lymph nodes, and/or fungal infection of the mouth and throat. Also referred to as symptomatic HIV infection.

AIDS service organization (ASO): A health association, support agency, or other service actively involved in the prevention and treatment of AIDS.

AIDS wasting syndrome: The involuntary weight loss of 10 percent of baseline body weight plus either chronic diarrhea (two loose stools per day for more than 30 days) or chronic weakness and documented fever (for 30 days or more, intermittent or constant) in the absence of a concurrent illness or condition other than HIV infection that would explain the findings.

Airborne virus: Germs people get through sneezing, coughing or touching their mouth, eyes or nose. Germs for colds and flu are transmitted this way, but not HIV which is a blood-borne virus.

Albumin: A protein found in bodily tissues and fluids; the principal protein in blood plasma. A reduced level of albumin in the serum of persons with AIDS-related wasting syndrome is a sign of progressive wasting and suggests a high risk of death.

Alcohol: The most commonly used drug in the United States that is legal for adults over the age of 21 (it used to be 18). In many countries, the “legal” age to consume and buy liquor is not enforced. A majority of older teens report that they have drank alcohol and got drunk, often as a prelude to sexual encounters. Youth consumption of alcohol is considered a major co-factor in teenage HIV risk and transmission. Most boys do not know that the male’s testosterone is destroyed by alcohol. Exercise may be better preparation for a sexual experience than alcohol.

Alienation: The fragmentation of individuals' relations to their work, the things they produce, and the resources with which they produce them. In teen terms, many youth feel alienation from parents and adult authority figures and institutions.

All that: Urban slang for a superior nature; wonderful or attractive. "She’s all that."

All up in my grill: Urban slang for being in someone's face.

Allele: A "version" of a specific gene. Each individual has 1 allele at each specific genetic location.

Allopathy (adj. allopathic): In “Western medicine," this refers to a therapeutic system in which illness or disease is treated by producing a second condition that is antagonistic toward or incompatible with the first (e.g., an antibiotic drug is given to treat infection with a microorganism).

Alpha interferon: Has been shown to be produced at high levels by white blood cells that are infected with HIV. It has been implicated as a predictor of AIDS and is associated with a greater likelihood of developing opportunistic infections.

Alternative therapy: Therapy that is not considered standard practice in most Western countries, e.g., traditional medicine (homeopathy such as herbal remedies, acupuncture or massage). Alternative medicine is also referred to as "complementary medicine." The designation "alternative medicine" is not equivalent to holistic medicine, a narrower term.

Altruistic act: A behavior characterized by self-sacrifice that benefits others. Dr. John’s PeerCorps teens act altruistically because they volunteer to help their friends and peers.

Amateur: 1. Not a professional for pay. 2. Slang for a young female who indulges in sexual intercourse frequently and with several males, without expectation of remuneration.

Ambisextrous: Bi-sexual (sex with either males or females).

Ambisexuality (adj. ambisexual): 1. Having characteristics shared by both sexes; from Greek, ambi, (both) plus sex. In human beings, for example, nipples and pubic hair. 2. Birth-defective genitalia that look hermaphroditically ambiguous or inter-sexed. 3. A more contemporary term for bisexual; a sexually active person who “swings both ways” (during adolescence, some teens experiment with friends of both sexes).

Ambulatory: Able to get out of bed and walk around.

Amebiasis: An intestinal inflammation caused by the Entamoeba histolytica (an ameba) and characterized by frequent, loose stools flecked with blood and mucus (not to be confused with AIDS’ wasting syndrome).

Amenorrhea: Absence of menstrual periods.

American Foundation for AIDS Research (AmFAR): AmFAR was co-founded in 1985 by Dr. Mathilde Krim and Dr. Michael Gottlieb. It remains an influential advocate for HIV/AIDS research and programs.

Amniotic fluid: The fluid within the amniotic sac that surrounds the embryo or fetus.

Amniotic sac: The pouch that contains the amniotic fluid.

Amphetamines: Amphetamines are stimulants or "uppers” usually made synthetically in illegal labs. Its effects include stimulation of the central nervous system; a sense of well-being and higher energy; a release of social inhibitions; and feelings of cleverness, competence, and power (these are similar to the effects of cocaine, but last longer). They are a controlled substance because they can be dangerous physically and psychologically.

Amyl nitrate: A drug that is inhaled to prolong or intensify orgasm by increasing blood flow to the genitals and distorting time perception. Its use is potentially very dangerous. It is now illegal to sell in many states but not all.

Anabolic steroid: A synthetic hormone used to increase muscle size and strength. Injecting steroids with shared needles is a cause for HIV transmission (among young males particularly). The synthetic hormone by itself does not transmit HIV; it’s the infected blood found in the shared syringe and needle.

Anal coitus: Sex in the rectum.

Anal eroticism: Sexual sensitivity in the anus or rectum; also anal fetish, a preoccupation with or preference for the anus or rectum.

Anal sex (a.k.a. sodomy): Sexual intercourse when the penis is inserted in the anus. Sometimes used as a birth control measure by young people so the female does not get pregnant; also a preferred sexual activity among young gay or bisexual males. Dr. John counsels that because the anal membrane can easily tear, anal sex carries a high risk for HIV transmission. It is a taboo practice in many societies and is often not acknowledged publicly. In cultures where males and females do not mix before marriage, anal sex among males is practiced as a means of sexual release.

Anaphrodisiac: A substance that decreases sexual capacity or desire. Opposite of aphrodisiac.

Anatomical sex: The apparent gender of an individual based on the appearance of sexual organs.

Andrin: The hormone produced by the male sex glands.

Androgens: The "male" sex hormones. Also produced by women as well (though in smaller quantities and with little absorption).

Androgeny (androgyny): The merging of masculine and feminine traits, feelings, and qualities.

Anemia: The name for a group of blood diseases caused by problems with red blood cells (also referred to as "low blood count"). Many times anemia happens in young people because they don't have enough iron.

Anergy: 1. The loss or weakening of the body's immunity to an irritating agent or antigen. Patients who are immunologically suppressed are unable to produce a reaction to an antigen. The lack of a reaction indicates anergy. 2. CD4+ T cells can be turned off by a signal from HIV that leaves them unable to respond to further immune system stimulation.

Angiogenesis: Process by which new blood vessels are formed. Angiogenesis is essential for tumor growth, especially Kaposi's sarcoma.

Angurya: Scraping of the vagina and surrounding tissues as a part of the harmful practice of female genital cutting (female circumcision).

Analingus (slang: rimming): Oral sex performed by putting the mouth on the anus. Performing analingus is a risky behavior for a variety of bacterial infections but it’s often foreplay before anal sexual intercourse. If dental dams (like a latex condom) are used properly and there is no exchange of blood or bodily fluids (other than saliva), analingus will not be a transmission route for HIV.

Anogenital: Refers to area that includes the genitals, perineum and anus.

Anonymous HIV test: A person doesn't give his or her name or address when an HIV test is taken. The person is given a number and uses that as their identification. When they go back to get their test results they give that number. This way, no one else can know the results. Dr. John counsels youth to get anonymously tested to encourage HIV testing.

Anorexia (anorexia nervosa): Prolonged loss of appetite. Young women with wasting syndrome due to HIV-infection are often diagnosed as anorexic. Teen girls sometimes starve themselves to lose weight to look sexy.

Anorgasmic (anorgasmia): Incapable of having an orgasm with normally conducive modes of stimulation.

Antenatal: The period between conception and birth (same as prenatal).

Anthropocentricity: The belief that humans are the most important element in the universe.

Anthropology: The study of humanity (our physical characteristics as animals), and the unique non-biological characteristics of our culture. The subject is generally broken down into three sub-disciplines: biological (physical) anthropology, cultural (social) anthropology, and archaeology.

Antibiotic: A substance that kills or inhibits the growth of organisms. Once considered a magic bullet, antibiotics are now commonly used to combat disease and infection. Many human viruses and bacteria are becoming resistant to current antibiotics.

Antibody (antibodies): Members of a class of proteins known as immunoglobins. Antibodies may tag, destroy and neutralize bacteria, viruses or other harmful toxins. Antibodies attack infected cells, making them vulnerable to attack by other elements of the immune system. Antibody production occurs in response to the presence of a foreign substance (antigen) in the body.

Antibody-Dependent Cell-Mediated Cytotoxicity (ADCC): An immune response in which antibodies bind to target cells, identifying them for attack by the immune system.

Antigay prejudice: Negative attitudes and behaviors toward homosexuals (often legally acceptable but it may be socially disapproved of).

Antigen: A foreign protein that causes an immune response (the production of antibodies to fight antigens). Common examples of antigens are the bacteria and viruses that cause human disease. Any substance that antagonizes or stimulates the immune system produces antibodies, proteins that fight antigens.

Antiretroviral: A substance that stops or suppresses the activity of a retrovirus such as HIV. AZT was the first widely used antiretroviral drug and now many more combinations of “AIDS cocktails” are reaching the market. Antiretrovirals are not a cure for AIDS but do help manage AIDS as a chronic disease and perhaps help strengthen a PWA's health. Antiretrovirals can cause side-effects, some serious.

Antisperm antibodies: Antibodies produced by a woman that attach to sperm and inhibit both their movement and their ability to fertilize the egg.

Antitoxins: Antibodies that recognize and inactivate toxins produced by certain bacteria, plants, or animals.

Antiviral: A substance that kills or suppresses a virus.

Anus: The opening of the rectum (the hole).

Aphrodisiac: A food, medicine, drink, etc. that increases sexual desire or improves sexual performance. Viagra was one of the first male anti-impotence “aphrodisiacs” on the market.

Aphthous ulcer: A painful oral or esophageal sore of unknown cause that has a deeply eroded base. Aphthous ulcers are common in persons living with HIV.

Apoptosis: Cellular suicide, also known as programmed cell death. A possible mechanism used by HIV to suppress the immune system. HIV may cause apoptosis in both HIV-infected and HIV-uninfected immune system cells.

Applewild School: Where Dr. John Chittick completed his early education (1963) and received the school’s first William Laverack Humanitarian Service Alumni Award for his Global AIDS Prevention Walks.

Applied anthropology: The activity of professional anthropologists in programs that have as primary goals changes in human behavior believed to ameliorate contemporary social, economic, and technological problems.

Approval process: For drugs in the U.S., the Food and Drug Administration (FDA) must approve a substance as a drug before it can be marketed; it takes 6 steps:
A). Preclinical -- laboratory and animal studies.
B). Company files for Investigational New Drug (IND) status with the FDA.
Step 1. Clinical trials begin: Phase I: testing for safety
Step 2. Phase II: testing for efficacy.
Step 3. Phase III: extensive clinical trials.
Step 4 Company files New Drug Application (NDA) with FDA for permission to market the drug.
Step 5. FDA review of application.
Step 6. FDA approval/rejection of application. Even after the NDA is approved, the company is required to periodically submit reports to the FDA, including adverse reactions data, production and quality control information and sometimes extended monitoring.

ARC (AIDS Related Complex): A person with HIV who has symptoms but not severe enough to be classified as having AIDS (term is now little used).

Arc of Erection: The angle at which the penis extends from the body when aroused; a very high arc when young males get erections.

Areola: The dark area surrounding the nipples of women and men.

Arm: One group of participants in a comparative clinical trial, all of whom receive the same treatment. The other arm(s) receive a different treatment regimen.

Around the world: The act of kissing the entire body but focusing on the genitalia as a prelude to sex. Usually one person orally pleases a passive partner.

Arranged marriage: Any marriage in which the selection of a spouse is outside the control of the bride and groom.

ART: AntiRetroviral Therapy.

Artificial insemination: Placement of sperm inside a woman's vagina, uterus, or fallopian tubes (usually by injecting them through a catheter or cannula) in order to promote fertilization.

Assembly and budding: Names for a portion of the processes by which new HIV is formed in infected host cells. Viral core proteins, enzymes, and RNA (ribonucleic acid) gather just inside the cell's membrane, while the viral envelope proteins aggregate within the membrane. An immature viral particle is formed and then pinches off from the cell, acquiring an envelope and the cellular and HIV proteins from the cell membrane. The immature viral particle then undergoes processing by an HIV enzyme called protease to become an infectious virus.

Assessment: A professional review of child and family needs that is done when services are first sought from a caregiver. The assessment of the youth includes a review of physical and mental health, intelligence, school performance, family situation, and behavior in the community.

Assisted Reproductive Technology (ART): Procedures used to bring about conception without sexual intercourse, including IUI, IVF, GIFT, and ZIFT.

Assortative mating: The preference or avoidance of certain people as mates for physical or social reasons.

Asexual (slang, frigid): Absence of sexual feeling.

A-Spot: Discovered by a gynecologist in Malaysia, the A-spot is said to have a role in female arousal. The A-spot is between the G-spot and the opening to the cervix and is thought to increase lubrication during intercourse.

Ass/Asshole: Slang expression for anus.

Assay: A test used to detect the presence or absence of a substance in tissue, cells or a body fluid such as blood or urine, and to estimate the amount present in the body.

Asymptomatic: When there are no visible or noticeable changes in the body; i.e., an HIV-positive person who does not show any signs of "AIDS symptoms." Thus, asymptomatic carriers are a threat to their unsuspecting sexual partners.

At risk: Individual behavior that identifies a person engaging in behaviors that are likely to transmit HIV. "Groups" per se are not at risk -- rather the commonly-practiced behaviors of their individual members make them more susceptible to be infected.

Attention-deficit/hyperactivity disorder (ADHD): A behavior disorder, usually first diagnosed in childhood, that is characterized by inattention, impulsivity, and, in some cases, hyperactivity.

Attenuated virus: An altered virus with a reduced ability to infect or produce disease. Attenuated virus are sometimes used as vaccines.

Atypical sexual behaviors: Sexual activities that do not commonly occur in society. There are many recurrent sexual fantasies and urges to do unusual sexual activities.

Autoantibody: 1. An antibody that is active against some of the tissues of the organism that produced it. 2. An antibody directed against the body's own tissue.

Autoerotic asphyxia (autoerotic strangulation): The practice of inducing cerebral anoxia, usually by means of self-applied ligatures or suffocating devices, while the individual masturbates to orgasm; also known as sexual hanging (purported to increase the intensity of orgasm but death can occur).

Auto-eroticism: Erotic, sexual pleasure created for oneself and engaged in alone. Masturbation (a.k.a., jerking off, beating off). Known as wanking (U.K.).

Autofellatio: For a male to perform oral sex on himself; putting his penis in his own mouth. It is sometimes practiced by adolescent males when their growing bodies are limber.

Autoimmune disease: A disease that arises from and is directed against an individual's own tissue (a major problem with transplants).

Autoimmune response: A response caused by the immune system mistakenly attacking the body's own tissues.

Autonomy: Taking commands from only one authoritative source: oneself, and rejecting all attempts to override one's autonomy. Moral autonomy entails making the final decisions about what one should do.

Average Penis Length: Penis size differs from male to male. The average length when erect is 4 ¼” – 7” (or 11 - 18cm) but there may be some variation between males of different cultures. The size is determined by factors called genetic traits which are inherited from parents. Frequent and long-term masturbation by teen boys can result in the lengthening of the penis (similar to how exercise increases build).

Azoospermia: Absence of sperm in the semen.

AZT: Retrovir and Zidovudine are the common names for the chemical 3'azidothymidine. It was the first drug on the market for AIDS. It was thought that AZT might be the cure for AIDS-related diseases. However, AZT is neither as good as its manufacturer claims, nor as bad as AIDS activists have alleged. In combination with other drugs (see "cocktail" therapies), it can be helpful in slowing the progress of HIV/AIDS. AZT definitely helps to cut down on the transmission of perinatal (mother to baby) AIDS.

Cell lines: Specific cell types artificially grown and maintained in the laboratory (in vitro) for scientific purposes.

Cell-mediated immunity (CMI): This branch of the immune system exists primarily to deal with viruses, which are more insidious than bacteria because they invade the host (e.g., human) cells, where they can hide from the antibody-making cells of the immune system. Within this system, the reaction to foreign material is performed by specific defense cells, such as killer T cells, macrophages, and other white blood cells rather than by antibodies.

Cellular immunity: Immunity that comes from the ability of cells to recognize invaders.

Censorship: The conscious act of denying people access to true facts. Some politicians, adults and school districts want to ban all sex ed and AIDS prevention information. Dr. John says, “Censorship of medical facts results in unnecessary teen HIV infections and more deaths by AIDS.”

Chemokines (beta chemokines): Studies of the relationship between HIV and these immune system chemicals have shown the complex exchanges that take place when HIV and white blood cells meet. Chemokines are intracellular messenger molecules secreted by CD8+ cells whose major function is to attract immune cells to sites of infection. Research has shown that HIV-1 needs access to chemokine receptors on the cell surface to infect the cell. Several chemokines-called Rantes, MIP-1A, and MIP-1B-interfere with HIV replication by occupying these receptors. Findings suggest that one mechanism these molecules use to suppress HIV infectivity is to block the process of fusion used by the virus to enter cells.

Circumcision (Slang, “cut”): 1. Male circumcision. Removing the foreskin of the penis, often done to infants. No conclusive evidence on whether or not circumcision has any effect on the likelihood of HIV transmission but some research suggests lower transmission of HIV if a male is circumcised. However, in South Africa, teen boys are circumcised as a group using the same ceremonial knife/spear and HIV blood can be passed from one to many. 2. Female circumcision. Mutilation of the clitoris to deny women sexual feeling; sometimes in the name of religion or culture. The UN has taken a strong stand against this kind of female mutilation.

Early in the epidemic, CD4 molecules were found to be the primary receptor for HIV on immune system cells. Recent data indicate that a second molecule, CXCR4, is also required for fusion and entry of certain strains of HIV into cells. New studies indicate a multistage interplay between HIV and two receptors on white blood cells. After binding to the receptor CD4, the virus fuses with a second receptor, CXCR4, which normally binds to chemokines. This double clasp may then signal the receptors to move the virus into the cell.
