E

Ejaculation—When semen is released from the penis during orgasm.

ELISA (Enzyme-Linked ImmunoSorbent Assay)—The most common test used to detect the presence of HIV antibodies in the blood, which are indicative of ongoing HIV infection. One type of ELISA is the preliminary test for HIV antibodies (to detect HIV infection). A positive ELISA test result must be confirmed by another test called a Western Blot.

Endocervical curettage—The removal of tissue from the inside of the cervix using a spoon-shaped instrument called a curette.

Endometrium—The mucous membrane that lines the uterus.

Epithelial—Refers to the cell linings covering most internal and external surfaces of the body and its organs.

Fomite—An object, such as a towel, bicycle seat, or an article of clothing, that is not in itself harmful, but is able to harbor pathogenic microorganisms and thus may serve as an agent of transmission for an infection. Many people think fomites can spread STDs, but there are very few documented cases of fomite transmission of any STD.

Foreskin—Loose skin at the head of the penis. This skin is sometimes removed in a procedure called circumcision, often performed during infancy.

Gay—An adjective used to describe people whose physical and/or emotional attractions are to people of the same sex.

Genital Ulcer Disease (GUD)—Ulcerative lesions on the genitals, usually caused by a sexually transmitted condition such as herpes, syphilis or chancroid. The presence of genital ulcers may increase the risk of transmitting HIV.

Genitals—The sexual organs on the outside of the body. For a male, this is the penis and testicles. For a female, this is the vulva and clitoris.

Glans—The head or tip of the penis.

Granuloma Inguinale—A sexually transmitted infection caused by Calymmatobacterium granulomatis. Causes ulcerated granulomatous lesions that occur in the inguinal regions and the genitalia.

Gynecologic oncologists—Doctors who specialize in treating cancers of the female reproductive organs.

Gynecology—The branch of medicine that involves care of the female reproductive system and breasts.

H

Helper T-cell—See CD4 Cell.

Herpes encephalitis—A rare, severe illness that occurs when the brain becomes infected with herpes simplex virus.

Herpes gladiatorum—The presence of herpes lesions on the body caused by herpes simplex virus infection that is transmitted usually through the abrasion of skin in a contact sport, such as wrestling.

Herpes whitlow—The presence of herpes lesions on the fingers or toes.

Herpes Zoster—See both Shingles and Varicella Zoster Virus (VZV).

Heterosexual—Sexual attraction to people of the opposite sex.

Hir—A gender-neutral pronoun.

HIV-2—Human immunodeficiency virus type 2, a virus closely related to HIV-1 that also leads to immune suppression. HIV-2 is not as virulent as HIV-1 and is epidemic only in West Africa.

Holistic Medicine —Various systems of health protection and restoration, both traditional and modern, that are reputedly based on the body’s natural healing powers, the various ways the different tissues affect each other and the influence of the external environment.

Homophobia—An irrational fear of or dislike of gay people.

Homosexual—Sexual attraction to people of the same sex This term is outdated and considered derogatory and offensive by many gay and lesbian people. The terms gay and lesbian should be used instead.

Hysterectomy—An operation in which the uterus and cervix are removed.

I

Immune Deficiency—A breakdown or inability of certain parts of the immune system to function, thus making a person susceptible to certain diseases that they would have not contracted with a healthy immune system. Immune deficiencies may be temporary or permanent and be triggered by genetic mutation, therapy with immune-suppressive drugs (as during organ transplants) or an infection such as HIV.

Immune System—The body’s complicated natural defense against disruption caused by invading microbes and cancers.

Immunity—Protection against disease. Immunity can be achieved for many infections–such as hepatitis A, hepatitis B, and some strains of HPV–through vaccination.

Immunocompetent—Refers to an immune system capable of developing a normal protective response when confronted with invading microbes or cancer.

Immunocompromised—Refers to an immune system in which the response to infections and tumors is subnormal.

Immunosuppression—Weakening of the immune response that occurs with HIV infection as well as with some antiviral or anticancer treatments.

Immunotherapy—Treatment aimed at reconstituting an impaired immune system. Examples of experimental immunotherapies for AIDS include passive hyperimmune therapy (PHT), IL-2 and therapeutic vaccines.

Impotence—The inability to attain and/or maintain an erection. Also referred to as erectile dysfunction.

Inflammation—The body’s response to tissue injury or infection which occurs in the affected tissues and adjacent blood vessels. Signs of inflammation are redness, swelling, pain, and sometimes loss of function. Not all of these signs are necessarily present in any given case.
