The answer is Testicles in men and ovaries in women.
Explanation:
In man, spermatozoa develop from cells called spermatogonias, which divide and form what are called first-order spermatocytes, then into second-order spermatocytes, where they then become spermatids, to finally become sperm cells. .
In the woman's ovary there are cells called ovogonias, which divide repeatedly to form first-order oocytes, these undergo two meiotic divisions and become secondary oocytes. These cells result in a haploid cell, called an ovule.
