|
ejaculation

ejaculatory duct
|
Tube through which semen enters the male urethra.
|
|
|
epididymis (plural; epididymides)
|
One of a pair of long, tighly coiled tubes lying on top of each testis. It carries sperm from the semiferous tubules to the vas deferens.
|
|
|
erectile dysfunction
|
Inability of an adult male to achieve an erection; impotence.
|
|
|
flagellum
|
Hair-like projection of a sperm cell that makes it motile (able to move).

faternal twins

|
|
|
glans penis

|
identical twins
|

|
|
|
impotence
|
Inability of an adult male to achieve an erection. From Latin in/im, not, and potentia, power.
|
|
|
interstitial cells
|
In the tests, these cells lie between the seminiferous tubules and produce the hormone testoterone. A pituitary gland hormone (luteinizing formone (LH) stimulates interstitial cells to produce testosterone.
|
|
|
parenchyma
|
Tissue composed of essential and functional cells of organ. In the tests, the parenchymal tissue includes seminiferous tubules that produce sperm.
|
|
|
perineum
|
External region between the anus and scrotum in the male.
|
|
|
prepuce
|
Fold of skin covering the tip of the penis. Also called foreskin.

|
Spermatozoa (sperm cells) and seminal fluid (prostatic and other glandular secretions).
|

|
seminal vesicle

|
Male gonad (testicle) that produces spermatozoa and the hormone testosterone. Remember: testis means one testicle, and testes are two testicles.
|
|
|
testosterone
|
Hormone secreted by the interstitial tissue of the testes; responsible for male sex characteristics.
|
|
|
vas deferens
|
Narrow tube (one on each side) that carries sperm from the epididymis into the body and toward the urethra. Also called ductus deferens.
