|
|
Ejaculation |
Ejection of sperm and fluid from the male urethra |
|
|
Ejaculatory duct |
Tube through which semen enters the male urethra |
|
|
Epididymis |
One of a pair of long, tightly coiled tubes on top of each testis. It carries sperm from the seminiferous tubules to the vas deferens. |
|
|
Erectile dysfunction |
Inability of an adult male to achieve an erection; impotence |
|
|
Flagellum |
Hair-like projection on a sperm cell that makes it motile (able to move) |
|
|
Fraternal twins |
Two infants born of the same pregnancy from two separate egg cells fertilized by two different sperm cells |
|
|
Glans penis |
Sensitive tip of the penis |
|
|
Identical twins |
Two infants resulting from division of one fertilized egg into two distinct embryos. Conjoined (“Siamese”) twins are completely separated identical twins |
|
|
Parenchyma |
The essential distinctive cells of an organ. In the testis, the seminiferous tubules that produces sperm are the parenchymal tissues |
|
|
Penis |
Male external organ of reproduction |
|
|
Perineum |
External region between the anus and scrotum in the male |
|
|
Testis |
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 the male sexual characteristics |
|
|
Vas deferens |
Narrow tube (one on each side) that carry sperm from the epididymis into the body and toward the urethra. Also called ductus deferens |
|
|
Prepuce |
Foreskin; food of skin covering the tip of the penis |
|
|
Prostate gland |
Exocrine gland at the base of the male urinary bladder. The prostate secrets the fluid part of the semen into the urethra during ejaculation |
|
|
Scrotum |
External sac that contains the testes |
|
|
Semen |
Spermatozoa (sperm cells) and seminal fluid (prostatic and seminal vesicle secretions) |
|
|
Seminal vesicles |
Paired sac-like male exocrine glands that secrete fluid (a major component of semen) into the vas deferens |
|
|
Seminiferous tubules |
Narrow, cooled tubules that produce sperm in the testes |
|
|
Spermatozoa |
Sperm cell |
|
|
Sterilization |
Procedure that removes and individual’s ability to produce or release reproductive cells |
|
|
Stroma |
Supportive, connective tissue of an organ, as distinguished from its parenchyma |
