WebCHAPTER 3 HUMAN REPRODUCTION As you are aware, humans are sexually reproducing and viviparous. The reproductive events in humans include formation of gametes (gametogenesis), i.e., sperms in males and ovum in females, transfer of sperms into the female genital tract (insemination) and fusion of male and female gametes (fertilisation) … WebPrimordial germ cells are the stem cells that, via mitosis, supply both spermatogonia and oogonia. In humans, spermatogenesis starts with a diploid (2N) spermatogonium that carries the full genetic compliment of 46 chromosomes (22 autosomal pairs, one X and one Y sex chromosomes). The spermatogonium represents the germ cell line from which all ...
