Reproductive System




The reproductive system allows the passing of genetic information from one generation to the next. The main sex hormone for the male is the testosterone. It is made by the testes. The testes also makes the sperm. The testosterone regulates the production of sperm and the develpment of the male. The testis is stored in epididymis. Sperm mature in the in the epididymis. The vas deferenes then passes through the prostate gland. As he sperm moves it mixes with fluids from several glands. This mix is called semen. To leave the body the semen passes through the uretha. The uretha runs through the penis. The penis is what transfers the semen into the female's body. The female part produces eggs andgives birth to developing individuals. The ovaries are what make the eggs. Estrogen is then released. That is the mai9n female sex hormone. Those are whatregulate the release of eggs and the development of the female. During ovulation, the agg is realesed into the fallopian tube. That tube leads from the into the uterus. If the egg ends up getting fertilized then the embryo enters the uterus. The uterus is the organ in which an embryo develops into a fetus. When the baby is born it passes through through the vagina and squeezes outside the body.
