I asked this question once before but really got no good answere... I just want to know the average amount of time it takes for the sperm to reach the egg. I have heard it can be moments or days.

and is the "conception" date the day the egg/sperm combo came to thier resting place.

If I had a very early ultrasound and it showed my conception date was 2/10/06. Does that mean I couldve actually had sex 3-5 days before that date, right?

(of course if you times sex at the same time as ovulation its how it goes)sperm fight to the finish
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 an easy journey it's not. 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.
The attrition rate for sperm is so high that only a few dozen 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 from the sperm combines with the genetic material in the egg to create a new cell that will rapidly start dividing. 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. (Although you can have an ectopic pregnancy if the embryo implants somewhere other than the uterus, usually in the fallopian tube. An ectopic pregnancy is not viable, and the embryo has to be surgically removed to prevent rupture and damage to the fallopian tube.) That final leg of the trip can take another three days or so, but it may be a few more weeks until you miss a period and suspect that you're going to have a baby.
Once you have missed your period — or noticed one of the other signs of pregnancy — you can use a home pregnancy test to find out for sure if you've got a little one on the way. If so, congratulations, and welcome to the start of another incredible journey.

Sperm Travel

The egg only survives for 24 hours. Sperm can live for up to 5 days. I've read that the sperm have to be present when the egg is released. I haven't confirmed that with my doctor yet though. Therefore, my guess is that the egg has to be fertilized within 24 hours, but it can be from sperm that have already been present for as long as 4-5 days. I have also read that the egg must be fertilized in the tube and that it takes on average 5 days for the egg to travel down to the uterus to implant.

Thee egg starts it's journey off from the ovary [could be right or left] the egg will travel through the fallopian tube, at which point you are most fertile and will meet the sperm. Fertilization takes places in the fallopian tube and the fertilized egg [baby] travels down the rest of the tube and implants into the uterus.

an egg lives 24 hrs and a sperm, 72 hrs. It takes precicely 6 hours for a normal sperm to reach an egg in the fallopian tube.

It can take up to six days after intercourse for sperm and egg to join and form a fertilized egg.

only a few hours. sperm got short life span. even if they can survive long. they will be too weak to penetrate a egg to fertilise it.
