Re: Does having an orgasim increase the chance a woman will become pregnant?

Scientific evidence on a relationship between pregnancy success and orgasm 
is difficult to collect. It is suggested however that female orgasm does 
assist fertilisation. The idea is that muscular contractions in the vagina, 
cervix and possibly uterus during orgasm help to carry sperm up through the 
woman's reproductive tract to the egg. However, there are many many more 
factors which contribute to pregnancy success that I don't believe female 
orgasm would play a significant role in the overall ability of a couple to 
become pregnant. Similarly, I doubt size of male orgasm is significantly 
involved in pregnancy success.
