Human fertilization is the union of a humanoid egg andsperm, usually occurring in the ampulla of the uterine tube. The result of this union is the production of a zygote, or fertilized egg, initiating prenatal development. Scientists discovered the dynamics of human fertilization in the nineteenth century.
The process of fertilization involves a sperm fusing with an ovum—usually following ejaculation during copulation. It is possible, but less probable, for fertilization to occur without copulation, artificial insemination, or In vitro fertilization.Upon encountering the ovum, the acrosome of the sperm produces enzymes which allow it to burrow through the outer jelly coat of the egg. The sperm plasma then fuses with the egg's plasma membrane, the sperm head disconnects from its flagellum and the egg travels down the Fallopian tube to reach the uterus.In vitro fertilization (IVF) is a process by which egg cells are fertilized by sperm outside the womb, in vitro.
