When I was in the military I knew a girl who made quite a bit of money with her ovaries, acting as a surrogate for other service families who couldn’t conceive. There wasn’t anything against the regulations about it, and it didn’t effect her job performance but after the third pregnancy the Air Force told her to cut it out because they were spending so much on her pre-natal care and she was pocketing the whole surrogacy fee.
