Human male reproductive system:-
The human male reproductive system comprises of the following.
- testes
- epididymis
- vas deferens
- Seminal vesicles
- prostate gland
- Cowper's glands
- penis
1. Testes
Testes produce male gametes and sperm.
To maintain the temperature 2-3°C lower than the body temperature, the scrotum is located outside the body cavity.
2. epididymis
The epididymis stores sperms temporarily.
3. vas deferens
Each epididymis continues further as a sperm duct or vas deferens.
4. Seminal vesicles
The seminal vesicles produce a secretion which is responsible for the transport of sperm.
5. Prostate gland
It is a bilobed structure which surrounds the urethra.
It pours an alkaline secretion into the semen.
6. Cowper’s glands

They open into the urethra.
Its secretion serves as a lubricant.
