Thanks, i didnt think about the salts lowering the freezing point thats a good point. When I was saying popsicle i think i was thinking of about lollipop size in my head, not like a big ole ice cream bar or anything. Is there anything that could go rancid in sperm...I mean is that part of the reason breeders and such use liquid nitrogen to keep it fresh(er)? And yes, were trying a lot of different things out, and i dunno why she wants it but she brought it up so i thought id do some research on it for her. Thanks for the help!
