Does pre-ejaculate fluid cause pregnancy? #270/8

Would you like to... Print this page Email this page Post a comment Subscribe me Add to favorites Remove Highlighting Edit this Question I ddn't get my period for 42 days. I usually get it every 30 days. I had intercourse with my guy on December 24th, a day after my period, but he didn't ejaculate inside my vagina. While having sex, when the sperm was about to come, he took the penis outside and ejaculated on the floor. The pre-ejaculate fluid went inside I guess. Do I have a chance of pregnancy? Do I have to take a pregnancy test??   We simply do not know how many sperm are in pre-ejaculate at various amounts of time prior to ejaculation.  This, along with the numbers of sperm in pre-ejaculate when sexual intercourse occurs at various intervals from the previous act of intercourse, is very poorly studied.   The earlier in an act of intercourse withdrawal occurs, the less the pre-ejaculate, and the less the likelihood of a full ejaculation into the vagina, I would assume.      There is extensive debate about the likelihood of pre-ejaculatory fluid causing pregnancy.  This is particularly true if your boyfriend/partner had not ejaculated recently.    In most instances, pregnancy is quite unlikely due to pre-ejaculate fluid. 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.    Unless you have had a clear period, sure, go ahead and get a pregnancy test.
