"Comparative studies in diverse species have revealed that long-term sperm storage (up to months
and years) within the female reproductive tract is relatively commonplace in reptiles, fishes, birds and
amphibians. Even among mammals, some species of bat have evolved mechanisms for storing
spermatozoa for several months in the uterus or oviduct so that they can mate in the autumn
but postpone fertilization until the spring."

in the egg's selection of a single sperm are not only interesting, but they're so complicated they make
my brain hurt. But, truth be known, topics like these have a pleasure to pain ratio of about 50 to 1
so the hurt is no big deal. In fact, that small chance of pain increases the thrill of the adventure.
Who knew reading scientific papers was so much like a bungee jumping?
