How many sperm are in pre-ejaculation fluid for the average man? #601/7
How many sperm are in pre-ejaculations for the average man?

There are very few sperm in a man's pre-ejaculate. The number of sperm in the pre-ejaculate and the likelihood of this pre-ejaculate to put a couple at risk for pregnancy remain 

unanswered questions.  The assumption is that pre-ejaculate is unlikely to cause pregnancy.


            Coitus interruptus prevents fertilization by preventing the contact between spermatozoa and the ovum.  The couple may have penile-vaginal intercourse until ejaculation is impending, at which time the male partner withdraws his penis from the vagina and away from the external genitalia of the female partner.  The man must rely on his own sensations to determine when he is about to ejaculate.  The pre-ejaculate, which is usually released just prior to full ejaculation, goes unnoticed by both the man and the woman during the course of intercourse and so it is not a sign that ejaculation is about to occur.

Did pre-ejaculation contain enough fertile sperm to cause my pregnancy? #627  Click here


Dr. Markus Steiner, I would be so appreciative if you would add to this answer.  If you know anything about the numbers of sperm in pre-ejaculate fluid, by all means, include in your answer.


Email from Dr. Markus Steiner on 6-11: "As far as semen in pre-ejaculate, I unfortunately do not have anything else to add to what you already have?it's one of those unanswered questions we often think a small study could quickly shed some light on, but to my knowledge nobody has yet."


Key Words:  sperms, pre-ejaculation, average man
