Fertilization that happens outside the female body is called in-vitro fertilization. In this procedure, the ova is fertilized with the sperm in a laboratory.
In 1974
Fertilization can occur in a lab in a petrie dish. That is how they do IVF. They then insert the fertilized egg into the uterus. But other than that it can not since eggs are inside the woman's body.
The woman dies and the body consumes it self
If fertilization does not occur, the egg will not implant in the uterus and will eventually disintegrate. The hormonal changes that are triggered by fertilization will not take place, leading to the shedding of the uterine lining. This process culminates in menstruation, where the body expels the unfertilized egg and the thickened uterine lining. Essentially, the cycle resets, preparing the body for the possibility of future fertilization.
Internal fertilization is a process in which the fertilization of an egg by sperm occurs inside the body of a female organism. This typically involves mating or copulation between males and females to transfer sperm to the female reproductive tract for fertilization to occur. Internal fertilization is common in mammals, reptiles, birds, and some fish.
Zebrafish exhibit external fertilization, where the female releases eggs and the male fertilizes them outside of the body. The embryos develop externally, with the early stages of development taking place outside of the mother's body in the water.

Aves, or birds, typically exhibit internal fertilization. In this process, the male bird transfers sperm to the female bird's reproductive tract before the eggs are laid. This adaptation allows for the fertilization of eggs to occur inside the female's body, which can enhance the likelihood of successful development of the embryos. After fertilization, the female lays eggs that develop outside her body.
