Even though only one sperm will fertilize an egg, why does it take more than one sperm being released from a man for this to occur?

The correct answer will be to increase the chances of fertilization.

Explanation:

A male ejaculate high number of sperms (50 million) out of which only in hundreds reaches the egg cell as they get exhausted, trapped and die on the way to the egg cell.

1. Out of 50 million only 1 million reaches the uterus as mostly are trapped in mucus and some get killed by the acidic nature of the vaginal wall.

2. Out of 1 million only 10,000 sperms swim to reach the openings of oviduct where one oviduct will have the eggs.

3. Only hundreds of sperm out of 10,000 reaches fallopian tube where the egg is lodged as rest dies in the fallopian tube as for the distance is long.

So many sperms get devastated and killed on the way to egg cell due to which the high number of sperms are released from the human male.
