Explain how sperms are formed from testes and transported to urinogenital duct.

Explanation

i. Testes contain numerous seminiferous tubules.
ii. Germ cells present in the tubules divide by meiosis to produce sperms.
iii. Sperms undergo physiological maturation, and their motility as well as the fertilizing capacity is increased in the head of epididymis.
iv. These sperms move forward sequentially through tubules-rete testes, vasa efferentia, epididymis, vas deferens, ejaculatory duct and urinogenital duct.
v. As these sperms reach the urinogenitial duct, they are ejaculated out through penis.
