Txt sperm fertilize her eggs
Human fertilization is the union of a human egg and sperm , usually occurring in the ampulla of the fallopian tube. Scientists discovered the dynamics of human fertilization in the nineteenth century. The process of fertilization involves a sperm fusing with an ovum. The most common sequence begins with ejaculation during copulation , follows with ovulation , and finishes with fertilization. Various exceptions to this sequence are possible, including artificial insemination , in vitro fertilization , external ejaculation without copulation, or copulation shortly after ovulation. 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.
