S.T.E.M.Human fertilisation

 

Animation of sperm cells attempting to fertilise a human egg (ovum). Fertilisation occurs when the sperm's genetic material (deoxyribonucleic acid, DNA) fuses with the egg's DNA, forming a zygote. Only one sperm cell may penetrate the egg's outer layer, as after that it becomes impervious to other sperm.
