A little about the video
A lot of numbers are thrown out there about the lifespan of sperm but here's the scoop: sperm can live as little as a couple of hours or as long as five days after sex. Once inside the vagina, the lifespan of the sperm depends on the woman's vagina, uterus, and fallopian tubes. Without fertile cervical fluid, sperm won't survive longer than a few hours inside the vagina or uterus if they make it that far. Many sperm die off in the very acidic vaginal canal within the first 12 hours. If they can make it past the uterus into the fallopian tubes using fertile cervical fluid channels, they can live there, waiting for the release of an egg.

Movie showing cervix pulling up sperm

WE spend so much of our fertile lives trying not to get pregnant that it can come as a shock to find that it's actually pretty hard to conceive when we want to. And to make matters harder, fertility experts now claim that women have to orgasm if they want to get pregnant. Dr Robert King is a lecturer in applied psychology at the University College Cork, Ireland, and he claims that orgasming can boost a woman's chance of conceiving by as much as 15 per cent. During his own clinical research, he found that when women orgasms, a unique reaction causes a man's sperm to be "sucked" to the dominant ovary, boosting the chances of conception.

And that's a surprisingly high percentage considering that you can conceive only around the time of ovulation - a small window of opportunity each month usually about 12 to 24 hours during which the egg is viable, or open for the business of fertilisation. Doesn't sound like much of an opening? Consider, then, that sperm are able to live to fertilise for a lot longer than an egg is willing to hang out, anywhere from three to six days.
