MALE REPRODUCTIVE SYSTEM AND ITS HORMONES :::
Male reproductive system consists of testes vas -deferens seminal vesicles prostate gland and penis
Testes ::
These are two oval shaped bodies situated one on each side in the scrotal bag The scrotal bags help testes to ascend or descend into and out of the body This movement helps in maintaining fixed temperature (little lower then the body temp ) around the testes Higher temperature reduces the production of spermatozoa In other words scrotum protects the testes from temperature fluctuations They are covered with a membranous layer called tunica albugenea
The section of the testis shows that it is partitioned into various lobules Each lobule is filled up with convoluted seminiferous tubules Each seminiferous tubule is 50cm in length and shows a germinal layer peripherally and various stages of spermatogenesis towards the centre in the centre lies number of spermatozoa Radiating peripherally are spermatids secondary spermatocytes primary spematocytes and spermatogonia in addition supporting cells of sertoli are also present
There are a few interstitial cells which secrete the hormone testosterone cells of sertoli are rich in glycogen and provide nutrition to spermatozoa
