Male Reproductive System Flashcards
Pair of exocrine glands near the male urethra. They secrete fluid into the urethra. Also called Cowper glands.
bulbourethral glands
Removal of the prepuce (foreskin). It is a common elective procedure performed shortly after birth.
circumcision
Ejection of sperm and fluid from the male urethra.
ejaculation
Tube through which semen enters the male urethra.
ejaculatory duct
One of a pair of long, tightly coiled tubes above each testis. It stores and carries sperm from seminiferous tubules to the vas deferens.
epididymis (plural epididymides)
Inability of an adult male to achieve an erection; impotence.
erectile dysfunction
Hair-like projection on a sperm cell that makes it motile (able to move).
flagellum
Fold of skin covering the head of the penis; prepuce.
foreskin
Two infants resulting from fertilization of two separate ova by two separate sperm cells.
fraternal twins
Sensitive tip of the penis; comparable to the clitoris in the female.
glans penis
Two infants resulting from division of one fertilized egg. Conjoined twins are incompletely separated.
identical twins
In a man, any problem that lowers the chance of his female partner getting pregnant.
infertility
Specialized cells that lie adjacent to the seminiferous tubules in the testes. These cells produce testosterone and are also called Leydig cells.
interstitial cells of the testes
Essential distinctive cells of an organ. In the testis, the seminiferous tubules that produce sperm.
parenchymal tissue
Male external organ of reproduction.
penis
External region between the anus and scrotum in the male.
perineum
Foreskin; fold of skin covering the tip of the penis.
prepuce
Exocrine gland at the base of the male urinary bladder. Secretes fluid that contributes to semen during ejaculation.
prostate gland
External sac that contains the testes.
scrotum
Spermatozoa and seminal fluid discharged from the urethra during ejaculation.
semen
Paired sac-like exocrine glands that secrete fluid into the vas deferens.
seminal vesicles
Narrow, coiled tubules that produce sperm in the testes.
seminiferous tubules
Sperm cell.
spermatozoon (plural spermatozoa)
Procedure that removes a person’s ability to produce or release reproductive cells; removal of testicles, vasectomy, and oophorectomy are types.
sterilization
Supportive, connective tissue of an organ, as distinguished from its parenchyma.
stromal tissue; stroma
Male gonad that produces spermatozoa and testosterone.
testis (plural testes); testicle
Hormone secreted by the interstitial tissue of the testes; responsible for male sex characteristics.
testosterone
Narrow tube (one on each side) carrying sperm from the epididymis toward the urethra.
vas deferens; ductus deferens
