External Fertilization in Humans
External fertilization is also seen among humans but it is not natural. When the female’s oviducts are blocked the sperm cannot reach the eggs to fertilize it. In this situation the doctors collect the eggs and sperm and keep it together for several hours for the fertilization to take place this is known as in-vitro fertilization. After fertilization, the zygote is transferred into the uterus of the female after a week and the development takes place inside the body of the female.
