Bilbourethral glands |
Pair of exocrine glands near the male urethra. They secrete fluid into the urethra (Cowper glands) |
|
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 above each testis. It stores and carries sperm from seminiferous tubules to the vas deferens.(Plural: epididymides) |
|
Erectile dysfunction |
Inability of an adult male to achieve an erection; impotence |
|
Fraternal twins |
Two infants resulting from fertilization of two separate ova by two separate sperm cells. |
|
Glans penis |
Sensitive tip of the penis; comparable to the clitoris in the female. |
|
Identical twins |
Two infants resulting from division of one fertilized egg into two distinct embryos. Conjoined twins are incompletely separated identical twins. |
|
Interstitial cells of the testes |
Specialized cells that lie adjacent to the seminiferous tubules in the testes. These cells produce testosterone (also called Leydig cells). |
|
Parenchyma tissue |
Essential distinctive cells of an organ. In the testis, the seminiferous tubules that produce sperm are parenchymal. |
|
Penis |
Male external organ of reproduction |
|
Perineum |
External region between the anus and the scrotum in the male |
|
Prepuce |
Foreskin; fold of skin covering the tip of the penis |
|
Prostate gland |
Exocrine gland at the base of the male urinary bladder. The prostate secretes fluid that contributes to semen during ejaculation |
|
Scrotum |
External sac that contains the testes. |
|
Prostrate |
Lying down |
|
Semen |
Spermatozoa (sperm cells) and seminal fluid (prostatic and seminal vesicles secretions), discharge from the urethra during ejaculation. |
|
Seminal vesticles |
Paired sac-like exocrine glands that secrete fluid (a major component of semen) into the vas deferens. |
|
Seminiferous tubules |
Narrow, coiled tubules that produce sperm in the testes. |
|
Spermatozoon |
Sperm cell. Plural: spermatozoa |
|
Sterilization |
Procedure that removes a person's ability to produce or release reproductive cells; removal of testicles, vasectomy, and oophorectomy are sterilization procedures. |
|
Stromal tissue |
Supportive, connective tissue of an organ, a disinguished from its parenchyma (also called stroma) |
|
Testis |
Male gonad (testicle) that produces spermatozoa and the hormone testosterone. Plural: testes |
|
Testosterone |
Hormone secreted by the interstitial tissue of the testes; responsible for male sex characteristics. |
|
Vas deferens |
Narrow tube (one on each side) carrying sperm from the epididymis toward the urethra (aka ducts deferens) |
