Just a hypothesis!

Aristidis Matsoukis

According to this study, the eggs choose the sperm which must fertilize them. Is this true? The paper is innovative and seems to open new horizons regarding the matter.

A K Shyam

Yes it is true at lease in humans as the eggs release a chemical chemoattractant that attract sperm. Primarily, it is a language of chemicals between egg and sperm. If you closely analyze copulation among animals, this is also based on similar ground and you don't find them mating as frequently as the humans.
