Topic Content:

  • Male Reproductive System of Mammals
  • Summary – Functions of Some Parts of the Male Reproductive System

The male reproductive system in man consists of testes (testis), vas deferens (sperm duct), penis and glands

Male reproductive organ

There are two testes which are oval shaped and each testis is enclosed in a wrinkled sac called scrotum. 

The scrotum: It serves as a thermo regulator that protects the sperm from high temperatures. 

The testes lie, outside the body cavity so that they are cooler than the heat of the body which favours rapid sperm production.
