I'm trying to conceive with the help of a friend who is donating sperm. He lives about 400 miles away, so I've been flying down based on when the ovulation tests I'm using are positive. However, the timing doesn't always work due to our work schedules and such, and even when it does, we usually only get to try once. I read online about how people treat semen from animals at home and ship it chilled all over the country for AI done by breeders. The "semen extender" is just some sugars and antibiotics. I was wondering if anyone has ever used this? It's obviously not FDA approved for humans, but since it's used for a bunch of different mammals, it seems logical it would keep human sperm alive as well. It says it can keep sperm for 2-3 days, possibly even more. This way my donor could mail his sample to me.
