2 To promote activity of sperm.
There are some nutritive material in prostate fluid which are of benefit to sperm.
3 To promote the liquefaction of semen.
Pancreatic juice protease in prostate fluid can promote the liquefaction of sperm.
4 To enhance the survival rate of sperm in vagina.

How does Prostate Fluid Influence Fertility
1 The secretion of prostate fluid decrease on male with
prostatitis. As a result, the activity and survival rate of sperm is influenced.
2 When the bacteria which infect the prostate is breeding, they secrete harmful material which damage sperm.
3 Vast nutrition is needed for the bacteria breeding, so the nutrition which are necessary for sperm living decreases. The quantity of sperm reduces.
4 Lots of acid elements are discharged by bacteria while they are breeding. The decrease of PH in genital tract, so acidosis occurs on sperm.
5 A mass of oxygen is consumed by bacteria, so there is no enough oxygen for the sperm.
