Is the chance of conceiving depend on amount of sperm a man ejaculate, I know it just takes one but I mean does the greater amount increase the chance, so the man who is ejaculaing a lot is more fertile than the man who is ejaculate is less and his ejaculate does not squirt farther?

Neither the amount of ejaculate or the further the "squirt" matters. The amount and distance has nothing to do with the chances of conceiving. If that were the case, very few women would become pregnant.

It is fine to have sex multiple times on that day to increase the opportunity for conception.

Unfortunately, this answer is not quite accurate. While the quantity of semen is not important and it is fine to have sex multiple sex on "that day" to increase the opportunity for conception, you must know the EXACT day of ovulation for this to work properly.

The egg is only viable for conception for approx 24 hours, take into account at least 6 hours for sleep, that leaves 18 hours for the "good" egg to be fertalized. With these statistics it is amazing that anyone gets pregnant!

But for this scenario to work you must know the exact day of conception. Otherwise it takes up to 90 days for the sprematozoa to regenerate within the bulbourethral gland.
