Re: Sperm to Egg
sperm can live for I think a max of 7 to 9 days but in specific circumstances.
what you really want is for the sperm to be ready waiting where the egg is released... so the sex prior to O is the most important..... you have the greatest chances.
once the egg is released, there's only a 24 hour window for fertilization to occur.
here's info from an article i found:
If conception is going to happen, it will be in the first few hours after sex. At this point, you can't do much except cross your fingers and hope, though some experts say the woman should stay on her back, with a pillow under her butt, for at least 20 or 30 minutes so gravity can help the sperm get to the waiting egg.
While you and your partner are enjoying a relaxing post-romp cuddle, a great deal of activity is taking place inside your body. Those millions of sperm have begun their quest to find your egg, and it's not an easy journey. The first obstacle is the acid level in your vagina, which can be deadly to sperm. Then there's your cervical mucus, which can seem like an impenetrable net except on the one or two days when you're most fertile and it miraculously loosens up so a few of the strongest swimmers can get through. But that's not all — the sperm that survive still have a long road ahead. In all, they need to travel about seven inches from the cervix through the uterus to the fallopian tubes. When you consider that they travel at a rate of roughly an inch every 15 minutes, that's quite a trip. The fastest swimmers may find the egg in as little as 45 minutes, while the slowest can take up to 12 hours. If they don't find an egg in the fallopian tubes at the time of intercourse, the sperm can wait there in a resting stage for up to 72 hours.
Only a few dozen sperm ever make it to the egg. The rest get trapped, lost — perhaps heading up the wrong fallopian tube — or die along the way. For the lucky few who get near the egg, the race isn't over. They have to work frantically to penetrate the egg's outer shell and get inside before the others. When the hardiest of the bunch makes it through, the egg changes instantaneously so that no other sperm can get in. It's like a protective shield that clamps down over the egg at the exact moment that first sperm is safely inside.
Now the real miracle begins. The egg will be fertilized within about 24 hours as the genetic material in the sperm combines with the genetic material in the egg to create a new cell that starts dividing rapidly. You're not actually pregnant until that bundle of new cells, known as the embryo, travels the rest of the way down the fallopian tube and attaches itself to the wall of your uterus."
