Structure of human testis:

The male reproductive system consists of a pair of testis. Testis are male reproductive organs and produce (male gametes) sperms and also secrete the
male sex hormone called testosterone.
Inside each testis, several lobules are present. Each lobule has several tubules called seminiferous tubules.
The epithelial cells lining these tubules are called germinal epithelium.
They undergo large number of mitotic divisions and one meiotic division to produce
spermatozoa. The spermatozoa are released into lumen of the seminiferous tubules.
The duct system of testis consists of vasa efferentia. They collect spermatozoa from seminiferous tubules.
Vasa efferentia continue as epididymis in which sperms are stored temporarily.
From epididymis sperms move into a tubule called vasdeferens.
