spermatophylaxis
Spermatophylaxis refers to the phenomenon where sperm stored in the female reproductive tract can remain viable and capable of fertilization for an extended period, often much longer than the typical lifespan of sperm in vitro. This stored sperm can then fertilize an egg at a later time, even if insemination occurred days or weeks prior to ovulation. This concept is particularly relevant in the context of assisted reproductive technologies and understanding animal reproductive physiology.
The duration of sperm viability in vivo can vary significantly depending on the species, the female's reproductive
The practical implications of spermatophylaxis include its role in natural fertilization, where it can increase the
