scrotum
skin-covered pouch in the groin divided into two sacs, each containing a testis and an epididymis
testis, testicle
one of the two male reproductive glands, located in the scrotum, that produce sperm and the hormone testosterone
sperm, spermatozoon
male gamete or sex cell produced in the testes that unites with the ovum in the female to produce offspring.
epididymis
coiled duct on the top and at the side of the testis that stores sperm before emission
penis
erectile tissue covered with skin that contains the urethra for urination and the ducts for secretion of seminal fluid (semen)
glans penis
bulging structure at the distal end of the penis (glans = acorn)
prepuce
foreskin; loose casing that covers the glans penis; removed by circumcision
vas deferens
duct that carries sperm from the epididymis to the ejaculatory duct (vas = vessel; deferens = carrying away)
seminal vesicle
one of two sac-like structures behind the bladder and connected to the vas deferens on each side; secretes an alkaline substance into the semen to enable the sperm to live longer
semen
a mixture of the secretions of the testes, seminal vesicles, prostate, and bulbourethral glands discharged from the male urethra during orgasm (semen = seed)
ejaculatory duct
duct formed by the union of the vas deferens with the duct of the seminal vesicle; its fluid is carried into the urethra
prostate gland
trilobular gland that encircles the urethra just below the bladder and secretes an alkaline fluid into the semen (pro = before; stat = stand)
bulbourethral glands, Cowper glands
pair of glands below the prostate, with ducts opening into the urethra, that adds a viscid (sticky) fluid to the semen
perineum
external region between the scrotum and anus in a male and between the vulva and anus in a female
