Found this - HTH
The reason some suggest you put you bum on a pillow is to guide the sperm towards the cervix by gravity...raised too high & the semen (seminal fluid, sperm) will just pool around the cervix and may hinder the sperms access through the cervix.
It's not really necessary to raise your bum up a little although some people may feel it helps them. As long as you lie down for about 20-30mins following sex then this gives the sperm a good chance of swimming up through cervix & into the uterus...after this time what's left will mostly be the seminal fluid (although obviously may still be a few sperm remaining but any that are swimming in right direction and not round in circles should be on their way !!!) The female sperm are slower but live longer & the male sperm are quicker but also don't survive as long.
