Well, I'm a repro tech in the itty bitty place of Fredericton, New Brunswick, Canada. We've been doing the frozen thing (implants, collections, shipping, etc.. etc..) for a few years now. Our success rate is currently at 85%, which is awesome. I think the usual average for frozen implants is around 70%. But, all could be great and you may still not get puppies. I tried frozen on my own bitch - couldn't ask for better progesterone timing, we knew the exact day her LH surge was and the exact time she ovulated, post thaw motility on the semen was 85% and she still didn't get pregnant. So, you have to remember that motility does not equal fertility. Best of luck, Sarah khylar_creek@xxxxxxxx __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!
