Semen is the fluid that comes out from the end of a man's penis when he has an orgasm and ejaculates. It is usually white, but may also be slightly grey or yellow.
Semen is made up of sperm (male cells for sexual reproduction) floating in a fluid called seminal plasma. Sperm, also called spermatozoa, are made by a man's testicles
Normal semen volume ejaculated each time is between 2 and 6 ml. 65% of the volume is from seminal vesicles, 30-35% is from the prostate and only 5% from the testicles. More semen usually comes out if a man has not ejaculated for many days
For your information, parameters that help for normal conception and pregnancy include - the following:-
