Re: What does that really mean?
It can be done to a mouse as well. Male ones anyway, uncross your legs chaps. I was once instructed on how to do it, it requires a soldering iron (cauteriser).
Vasectomised male meeces are required for making transgenics and knockouts. Females go into Pseudopregnancy when mated. So you mate females to Vas males to produce ready recipients for your genetically altered eggs/blastocysts.
