    There is some thought that timing has to do with males vs females due to the size/speed/longevity of the sperm cells. The "male" sperm are smaller and faster, but don't live as long as the slower, larger "female" sperm.

    The thought is that you can either centrifuge down the semen sample and draw off the bottom of the tube (where the heavier "female" sperm will be) for more females, or by breeding early you can get more females since the males will have already made their run upstream and died by the time the eggs are ripe and ready for fertilization. I personally haven't had that experience but know breeders who swear by both techniques....

    They do swim, but there is a much higher mortality rate and damage rate to the individual sperm cells. They also don't live as long. That is why it is so critical to literally "bathe" those ripened eggs in the previously frozen semen to ensure that they are right where the remaining living sperm cells are able to swim to fertilize without wasting excess time/energy to get there...

    It's interesting that you say that. I have a male that seems to throw 70 to 80% males every litter. This last litter I bred I wanted a female out of it and I had alot of interest in females So I applied the theory and let them breed the second they were both willing. hoping that a good percentage of the male semen would die by the time the eggs dropped. It seems to have worked or just a coincidence but either way we got 6 females and 4 males. and that is a first.
