You are probably right but on the other hand it makes sense to me that immature sperm would. Oh heck i don't know but I kind of have always blamed the flea medicine I put on her right about the time the embryos were forming. Vet of course leans more to it being the studs young age. But he woujld since he is the one that told me to the medicine on her, which I washed off almost immediately. This was in my first breeding. I have learned a lot since then.
