Answer:
Semen
Explanation:
Semen includes sperm and the secretions provided by the sex glands of the male reproductive system. These glands are seminal vesicles, prostate, and bulbourethral glands. The secretion from the seminal vesicles is an alkaline and viscous fluid. It serves to neutralize the acid in the female reproductive tract.
It provides fructose for ATP production by sperm. The secretion from seminal vesicles also regulates sperm motility and viability. It helps semen coagulate after ejaculation. The secretion from the prostate gland has enzymes that break down clotting proteins from the seminal vesicles. The secretion from bulbourethral glands neutralizes the acidic conditions of the urethra.
