So far, researchers have birthed mice spawned from two mothers (in 2004) or two fathers (2010) by uniting the genetic material of egg with egg or

The film depicts several sperm attempting to fertilize the egg, «zooms in» on one sperm's tail to show how the dynein proteins move in sync to cause the tail to bend and flex, and
ends with the sperm's successful journey into the egg and the initiation of cell division that will ultimately create a new organism.
Now researchers are hoping to keep this subspecies alive by artificially fertilizing Najin and Fatu's eggs
with sperm frozen from male northern white rhinos and then implanting the fertilized eggs into a female southern white rhino — a subspecies that was also threatened but has since grown exponentially because of conservation efforts.
Blood wants to be inseminated
with the sperm abroad, but the HFEA says that the sample can not be released because the husband did not give his written consent.
