Question

Of the 200 to 400 million sperm cells released in a typical ejaculation, approximately how many do you think will reach the ovum?

Answer 1

Only 200 out of 2 000, 000 sperm cells reach the ovum. And only one (in exception to very rare cases of two) sperm cells actually participate in the process of fertilization. In comparison, an average female only produces 400 of egg cells during their lifetime, but the eggs cells are significantly larger than sperm cells.
