According to WebMD, the fastest sperm can get to a fallopian tube is about 30 minutes, meaning that the quickest conception could occur following sex is in the half-hour range . This means that, following sex, the egg could be fertilized before you've gotten up to get a drink of water.
According to Harms, conception can occur as many as five days after sex or possibly longer, as strong, healthy sperm can survive for about that many days (and perhaps even longer) in the supportive environment of the fallopian tubes as they wait for an egg to be released, if one isn't already present. Here's how it works: Fertilization happens in one of the fallopian tubes, which carries an egg from an ovary to the uterus. It can take up to seven days after intercourse for sperm and egg to join and become a fertilized egg. Usually, it's because the sperm gets into the fallopian tube before the egg is released.

Yes, there is a chemical attraction to the egg, the egg has a protein sperm swim towards.
I would say at least a couple of hours, but it could take up to three days. Depending you your body and where the egg is in the cycle.
I THINK IT TAKES 2 TO 3 DAYS DEPENDING ON
well, the sperm can last up to 3 days inside a women.
so around 3 days, but sometimes it dies before it can even reach it.
:)
It can take 12 - 72 hours for human sperm to reach the egg.
Only males have sperm. There is no such thing as female sperm.
It only takes sperm a few minutes to get inside of an egg.
The sperm and egg cell reach each other in the water and fertalize the egg
Yes, it is possible for 2 sperm to reach the egg, however only one will fertilize the egg. It isn't uncommon for more than 2 to reach the egg, depending how are along the egg is down the falopian tube. And how much sperm was ejaculated.
a sec
the sperm just die
the sperm just die
It can take a matter of hours depending on how much sperm there is
Sperm only live up to a maximum of three days. But they also have to REACH the egg which they can do within an hour. Therefore fertilisation could happen in one hour after sex, or if you had sex yesterday, the sperm could be lying in wait for the egg to come to them!
When the sperm enters the egg it's instantaneous.
If the sperm are not "healthy" or present in enough numbers they will will not have the ability to reach and female egg and then penetrate and fertilize then egg.
