Explanation:
The semen is not only made up of sperm. It also consists of secretions coming from three accessory glands: <u>seminal vesicles, prostate gland and bulbourethral gland.</u>

The prostate glad, on the other hand, secretes a fluid that accounts for <u><em>1/3 volume of the semen.</em></u> This contains the Prostate Specific Antigen (PSA) that thins the semen.
The bulbourethral gland is also known as<em> "Cowper's gland." </em>This produces a secretion that ensures the sperm's motility.
