Testicular cancer
A malignant tumor of the male sex organ (testicle) that normally produces the hormone testosterone. It is one of the most common cancers in young men. Most testicular cancers are found by men themselves, as lumps in the testicles. The risk of testicular cancer is increased in males whose testicles did not move down normally into the scrotum during childhood (undescended testicles). When a growth in a testicle is detected, cancer is confirmed after surgical removal of the affected testicle (orchiectomy) and examination of the tissue under a microscope. Testicular cancer is almost always curable if it is found early.

- Testicular feminization syndrome
Now more appropriately called the complete androgen insensitivity syndrome, this is a genetic disorder that makes XY fetuses insensitive (unresponsive) to androgens (male hormones). Instead, they are born looking externally like normal girls. Internally, there is a short blind-pouch vagina and no uterus, fallopian tubes or ovaries. There are testes in the abdomen or the […]
- Testicular self-examination
A monthly procedure for detecting the early signs of testicular cancer. Men should check the testes visually for new swelling or other changes on the skin of the scrotum, roll each testicle between thumb and fingers to detect internal growths, and check the cord (epididymis) on the top and back of each testicle for growths.

- Testing, anonymous
Testing in which no name or other means is used to identify the person tested. There is total anonymity. For example, the State of Florida requires that each county have a site for anonymous HIV testing.
- Testis
The male sex gland, located behind the penis in a pouch of skin called the scrotum. The testes produce and store sperm and are also the body’s main source of male hormones, such as testosterone. These hormones control the development of the reproductive organs and other male characteristics, such as body and facial hair, low […]
- Testosterone
A “male hormone” — a sex hormone produced by the testes that encourages the development of male sexual characteristics, stimulates the activity of the male secondary sex characteristics, and prevents changes in them following castration. Chemically, testosterone is 17-beta-hydroxy-4-androstene-3-one. Testosterone is the most potent of the naturally occurring androgens. The androgens cause the development of […]
