Create sex cells. Currently accepted medical theory is that while men make new sperm cells practically continuously for their adult lives, women are born with all of the eggs they will ever have.
However, this is challenged by stem cell research in mice, which found that female mice could renew their supply of eggs, and that this could also be possible in female humans.
This is a rather mature sort of riddle intended for an older audience. The answer is produce reproductive material (gamete cells). Women are born with all the egg cells they will ever produce. Grown men, on the other hand, produce sperm cells daily.
A woman's ova remain in an immature form until up to a year before menstruating when that particular batch starts to develop, and then by the time of the period, there is generally only one. The rest in that batch are used up as a part of hormone production.
