Human male reproductive system consists of 2 testes, each of which are located inside a sac-like structure called scrotum.
Each testis has about 250 compartments called testicular lobules.
Each testicular lobule contains 1- 3 seminiferous tubules, inside which the spermatogenesis occurs.
The seminiferous tubules of each testis open into a network of delicate tubules called rete testis. Rete testis opens into vasa efferentia.
