Accessory organs of male reproductive system

1) Prostate gland

• It contributes to the 30% of semen volume.
• It produces milky alkaline fluid that neutralize the acidity of female reproductive tract and helps the sperms to survive.

2) Seminal vesicles

• It contributes to the 60% of semen volume.
• Seminal fluid contains fructose that provides nutrition and energy to the sperm.

3) Bulbourethral glands

• It contributes to the 10% of semen volume.
• It produces mucus type of fluid to lubricate the female reproductive tract.
