Human Female Reproductive System

Reproduction in human :
Male Reproductive System : The human male reproductive system consists of the following organs :

A pair of testis lies in a small sac-like muscular structure outside the abdominal cavity called Scrotum. The function of testis is to produce sperm and male sex hormone called testosterone. The scrotum provides the optimal temperature for formation of sperms.
Epididymis is a coiled tube-like structure firmly attached to the testis and serves as the storehouse of sperms. Inside the epididymis, sperms become mature and develops motility.
Vas deferens The sperms are carried by a long tube called vas deferens or sperm duct into organs called seminal vesicles, where the sperms get nourished and stored.
Seminal vesicle is a glandular structure which joins vas deferens to form ejacuatory duct.
Ejaculatory duct enters prostate gland and joins urethra to form common urino-genital duct.
Penis is a copulatory organ at the tip of which urinogenital duct opens.
