Sperm Displacement

Sperm displacement is a natural process where, during reproduction, some sperm from previous sexual encounters can interfere with or reduce the chances of new sperm from a recent partner reaching the egg. Certain factors, like the presence of younger, more motile sperm or specific shared reproductive traits, can cause a partner's sperm to be displaced or pushed aside. This process helps select the most competitive sperm, potentially increasing the likelihood of successful fertilization. It's a complex interaction influenced by biology, reproductive timing, and sperm quality, playing a role in natural human fertility and reproductive strategy.
