Fertilization is far more complex than the old idea of “the fastest s***m wins.”
Modern research suggests that the egg may play a more active role in the selection process than previously believed.
Chemical signals released by the egg can influence which s***m are attracted and how they behave, creating a highly selective biological interaction.
This means reproduction is not simply a race—it’s a sophisticated communication process between two cells.
Nature is often more intelligent and selective than we imagine.
