The human male reproductive system consists of:
- Testes - Are the primary reproductive organs in males which are in pair. These are oval shaped organs which lie outside the abdominal cavity. It makes the male *** cells called sperms and produces male *** hormones called testosterone. The testes are situated in the scrotal sac outside the main body cavity because the formation of sperms requires a lower temperature than the normal body temperature.
- ******* - Is a muscular pouch which houses the testes. It is present outside the abdominal cavity and maintains a lower temperature than the normal body temperature.
- Epididymis - The sperms formed in the testes goes into a coiled tube called epididymis which stores the sperms temporarily.
- Vas Deferens (sperm duct) - It is a long tube which carries the sperms from epididymis to another tube called urethra.
- Seminal vesicles and prostrate gland - Both these glands are present along the path of vas deferens and add their secretions to sperms which allows them to transport easily.
- ***** - It is an organ which passés the sperms from the man's body into the ****** in the women's body during mating.
The secretions of seminal vesicles and prostrate gland provide nutrition to the sperms and also make their transportation easier by secreting a thick liquid.
