- 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
These are two small ovoid glands.
They open into the urethra.
Its secretion serves as a lubricant.

The urethra passes through the penis.
It carries either urine or semen at a given time.
