Can animal sperm fertilize a woman?

Published in Reproductive Biology 1 min read

No, animal sperm cannot fertilize a human female. The sperm and egg of different species have evolved to be incompatible at a fundamental level.

  • Species-specific receptors: The sperm of one species has specific receptors that match with the egg of the same species. Animal sperm lacks the necessary receptors to bind with and penetrate a human egg.
  • Genetic differences: The genetic makeup of different species is significantly different, making it impossible for animal sperm and human eggs to create a viable embryo.

While there have been successful instances of interspecies fertilization in laboratory settings, such as in the case of rabbits, these are extremely rare and do not translate to natural conditions.
