A friend of mine asked her DH-to-be to do a sperm test before marrying him (she also did a full fertility check before marrying him, so that it's equal but he didn't insist on it), which got me thinking. I can't say that lots of people know about it, so it wasn't like she told the world about it, but our group of 4 closest friends do, one of them was completely outraged.
Would you consider leaving your DP if you knew he was infertile or had poor sperm? Would you get him to do a sperm test before marriage?
