The human body has genitals that depend on gender. If this is a man, then the testes, their ducts and the penis form the reproductive system. There is also a scrotum in which sperm are produced. In women, the reproductive system is represented by the uterus, fallopian tubes, ovaries and vagina. Female reproductive cells – eggs – are formed in the ovaries. During intercourse, fertilization occurs – the fusion of the sperm and the egg. Fertilization occurs a few hours after the sperm has “entered” through the vagina into the female body. After fertilization, the egg begins to divide, passes one of the fallopian tubes and enters the uterus, where it attaches and begins to develop. This is how the long process of embryogenesis begins.
