A serious sexually transmitted disease (STD) that, without treatment, can lead to heart disease, nerve disorders, brain damage, mental disorders, blindness and death.

Sunna circumcision
The removal of the tip of the clitoris and/or its hood or covering (prepuce).

Testicles (testes; singular testis)
Part of the male reproductive system, the testicles manufacture the male hormones, including testosterone, and produce sperm, the male reproductive cells. The testicles are located inside the scrotum, the loose sac of skin that hangs below the penis.

Testicular self-examinations (TSE)
A procedure to detect changes in the testicles by rolling them between the fingers and thumbs of both hands to check for any lumps.

Testicular torsion
A condition in which the spermatic cord gets twisted around a testicle, cutting off the testicle’s blood supply. Symptoms of testicular torsion include sudden and severe pain, enlargement of the affected testicle, tenderness, and swelling. This condition requires emergency treatment.

Testosterone
The male hormone that is essential for sperm production and the development of male characteristics, including muscle mass and strength, fat distribution, bone mass and sex drive.Women also make small amounts of testosterone in the ovary.

Total abdominal hysterectomy and bilateral salpingo-oophorectomy (BSO)
A surgical procedure in which the uterus, fallopian tubes and ovaries are removed through an incision (cut) in the abdomen.

Total bilateral salpingo-oophorectomy (BSO)
The removal of the fallopian tubes and ovaries.

Total pelvic exenteration
A surgical procedure that involves the removal of the bladder, the lower part of the colon, the rectum, the female reproductive organs and sometimes the vagina. It is a radical surgery that usually is done only when cancer has spread within the pelvis.

Transvaginal ultrasound
Ultrasound uses sound waves (not radiation) to create images in internal organs. During a transvaginal ultrasound, a probe inserted into the vagina releases sound waves that echo off the tissue of the pelvic organs.

Transsexual
An individual who is committed to altering his or her physical appearance—through cosmetics, hormones and, in some cases, surgery—to resemble the opposite sex.

Transvestitism
The practice by heterosexual males of dressing in female clothes to produce or enhance sexual arousal. Also called transvestic fetishism.

Trichomoniasis
An infection that most often occurs in a woman’s vagina. A man also can get the infection in the urethra (the tube that carries urine out of the body), as well as in the prostate. It is caused by a tiny single-celled organism known as a "protozoa."

Tubal ligation
Surgery to "tie the tubes" (fallopian tubes) of a woman, which causes permanent sterility by preventing transport of the egg (ovum) to the uterus.

Tumor
A mass of tissue that forms when cells abnormally divide. Tumors can be benign (not cancer) or malignant (cancer).

Ultrasound (sonogram)
The use of sound waves to form an image of internal organs.

Undescended testicle
A condition in which the testicles do not descend from the abdomen, where they are located during development, to the scrotum shortly before birth. Also called cryptorchidism.

Urethra
The tube that carries urine from the bladder to outside of the body.

Urinary tract infection (UTI)
A condition that occurs when bacteria from outside the body get into the urinary tract and cause infection and inflammation.

Urogynecologist
A doctor who is specially trained to treat problems of the female urinary system.

Uterine fibroids
Nodules of smooth muscle cells and fibrous connective tissue that develop within the wall of the uterus (womb). Medically, they are called uterine leiomyomata (singular: leiomyoma).

Uterus
The hollow, pear-shaped organ where a baby grows.

Vagina
The tube that joins the cervix (the lower part of uterus, or womb) to the outside of the body. It also is known as the birth canal.

Vaginal cancer
Cancer of the vagina.

Vaginal discharge
A clear or whitish fluid that comes out of the vagina. The uterus, cervix or vagina can produce the fluid. A foul-smelling, yellow or green discharge is abnormal and should be evaluated by a health care provider.

Vaginal intraepithelial neoplasia (VAIN)
A condition that often begins as pre-cancerous changes in the surface cells of the vagina.

Vaginectomy
The surgical removal of the vagina. It is sometimes used to remove cancerous growths. If all or part of the vagina is removed, the vagina must be reconstructed using tissue from another part of the body.

Vaginoplasty
A procedure in which the bulk of the penis tissue is removed, but the outer skin is reshaped, turned "inside out" and inserted into the body to form a vagina. This procedure is done during male to female gender reassignment surgery.

Vaginismus
A painful, involuntary spasm of the muscles that surround the vaginal entrance.

Vaginitis
A medical term used to described various disorders that cause infection or inflammation of the vagina.

Vascular assessment
An evaluation of blood flow.

Vasculitis
An inflammation of blood or lymphatic vessels. This inflammation can lead to the formation of scar tissue.

Vas deferens
The long, muscular tube that travels from the epididymis into the pelvic cavity, to just behind the urinary bladder. The vas deferens transports mature sperm to the urethra in preparation for ejaculation.

Vasectomy
A permanent sterilization procedure for men. The operation, usually done in a physician's office, requires cutting and sealing the vas deferens, the tubes in the male reproductive system that carry sperm. A vasectomy prevents the transport of sperm out of the testes.

Viral vaginitis
A form of vaginitis (infection or inflammation of the vagina) caused by viral infection. One form caused by the herpes simplex virus (HSV) is often just called "herpes" infection. These infections also are spread by sexual contact.

Virus
A microorganism (germ) that causes various infections.

Voyeurism
A disorder that involves achieving sexual arousal by observing an unsuspecting and non-consenting person who is undressing or unclothed, and/or engaged in sexual activity.

Vulva
The area of skin between a woman’s legs that includes all of the visible (external) organs of reproduction.

Vulvar cancer
Cancer of the vulva.

Vulvar intraepithelial neoplasia (VIN)
Pre-cancerous changes in the surface cells of the vulva. Also called dysplasia.

Vulvectomy
Removal of the vulva. Skinning vulvectomy is a procedure in which the skin of the vulva that contains the cancer is removed. Simple vulvectomy is a procedure in which the entire vulva is removed, but no lymph nodes. Partial vulvectomy is a procedure that removes less than the entire vulva. Radical vulvectomy is a procedure in which the entire vulva is removed, and lymph nodes in the groin usually are removed.

Vulvovaginitis
Inflammation of both the vagina and vulva (the external female genitals).

Watchful waiting
Careful observation without immediate treatment.

Wide local excision
A procedure in which the doctor removes only the cancer and some normal tissue surrounding the tumor.

X-ray
High-energy radiation used in low doses to create images of the body to help diagnose diseases and determine the extent of injuries.

Yeast infections
Infections of the vagina caused by one of the many species of fungus called Candida. A change in the chemical balance in the vagina allows the fungus to grow too rapidly and cause symptoms of vaginal discharge, itching and or pain.
