male reproductive system
consists of the testes, various ducts, the urethra, and the following accessory glands: bulbourethral, prostate, and the seminal vesicles
scrotum
the pouchlike structure located behind and below the penis; it acts as a natural climate control center for the testicles in order to maintain viability of sperm; the temperature in the scrotum is a degree or two lower than the usual body temperature of 98.6*F, which would kill sperm
penis
the external male sex organ and is composed of erectile tissue covered with skin; acts as a male organ of copulation and urination; site of the orifice for the elimination of urine and semen from the body
testes
two ovoid-shaped organs, located within he scrotum; they provide the male sex hormone, testosterone, provided by cells within them; contain seminiferous tubules that are the site of sperm formation and development
epididymis
tubes connected to the testes along which sperm passes to the vas deferens; acts as a site for the maturation of sperm
vas deferens
also called the ductus deferens, it is a slim muscular tube, about 30-45cm in length, and is a continuation of the epididymis; it acts as a excretory duct of the testis
seminal vesicles
there are two of these vesicles connected by a narrow duct to a vas deferens; it produces a slightly alkaline fluid that becomes a part of the seminal fluid or semen
prostate gland
it is composed of glandular, connective, and muscular tissue and lies behind the urinary bladder; secretes an alkaline fluid that aids in maintaining the viability of spermatozoa
Bulbourethral glands (Cowper’s glands)
two small pea-sized glands located below the prostate and on either side of he urethra; produce a mucous secretion before ejaculation, which becomes a part of the semen
urethra
the duct about 20cm long that is divided into three sections: prostatic, membranous, and penile; transmits urine and semen out of the body
anorchism
condition in which there is a lack of one or both testes
