StopLearnStopLearnThe male reproductive system in man consists of testes, vasa efferenctia, vas deferend (spermdnut penis and glands)
There are two testes in male animal. Each testes is oval in shape and is housed in a wrinkled sac called scrotum which hangs out of the body behind the penis. The scrotum functions as a thermoregulator that protects the sperm from high temeperature. The body temperature is to high for the formation of sperm hence the testes are positioned out of body that is slightly water (2 or 30c lower) than the normal body temperature.
Each testis is made of a large number highly coiled tubes called seminiferous tubules and interstitial cells which lie with the seminiferous tubules. The seminiferous tubules produces the sperm while the interstitial cells produce testosterone.
are small number of tubes which are connected with seminiferous tubules and unite to form epididymis, vasa deference collect sperms from the seminiferous tubules to the epididymis
This is highly coiled tube about 6 metre long which receives sperm from vasa efferentia. Sperm are temporarily stored to mature and develop in the epididymis.
it serves as a passage for both urine and sperm
the seminal reside is a small sac where sperms are stored. It is located close to the posterior end of vas deferens. It secrets seminal fluid. Seminal fluid contains fructose which provides energy for the sperm.
Three glands open into the male reproductive system. These are seminal fluid, prostate glant and cooper’s gland.
The prostate gland is located a little below the bladder while a pair of cowper’s gland is situated below the prostate gland. These three glands secret seminal fluid in which sperm swim. The fluid activities sperm and into swimming. It provides food for the sperm and lubricates the passage. The sperm swim freely in the seminal fluid. The acidity of the urine is neutralized by the seminal fluid.
The seminal fluid plus the sperm make up the semen.
