Seminal vesicles secretes Seminal fluid. This is lubricating, transparent and jelly like substance, which makes 60-70% part of semen. It is slightly alkaline (pH = 7.3). Fructose is found in seminal fluid, it act as fuel to sperm. Fibrinogen , prostaglandins, citrate , inositol are also present in semen.
Prostate gland secretes slightly alkaline prostatic fluid which is milky, thick, and jelly like. It makes about 30% part of semen and helps in sperm activation.
It's secretion also has citric acid, calcium and phosphate, clotting enzymes and fibrinolysin .
Secretions of both the glands get mixed and semen gets coagulated. In the coagulated semen, the mobility of sperm is highly reduced and so their energy is conserved. After some time, due to fibrinolysins, semen again liquefies and in this semen now the sperms can move.
