The reproductive system involves the male and female. The reproductive system allows the human race to produce offspring.
Fertilization occurs internally inside the fallopian tubes, where the sperm meets the egg. The egg will travel into the uterus, where the egg will implant itself into the endometrium. The egg will develop into an embryo and then into a fetus. The fetus will grow and develop over a course of 40 weeks, and then the baby will be born.
