Also asked, can a person run out of sperms?

Unlike women who have a set number of eggs from birth, men are constantly creating new sperm, so it is not possible to “run out” of sperm.

Beside above, are we the sperm or the egg? Human fertilization is the union of a human egg and sperm, usually occurring in the ampulla of the fallopian tube. The result of this union is the production of a zygote cell, or fertilized egg, initiating prenatal development.

Likewise, people ask, is it really the first sperm that fertilizes the egg?
