This is actually what helped me make the decision when I was pg with DS, I didn't know if he was a boy or a girl. If DD had been a boy, she may have been circ'd, I really don't know-because
I didn't know any better.
The biggest reason for me was that DH was one of 7 children and he was the only one who had to stay in the hospital for an extended time due to the fact his circ would not stop bleeding

When pg with DS I had found MDC and read the boards here on circ, I started reading links and realized there was NO WAY I would let my baby have anything like that done to them. I was very scared that something similar could happen and then read about babies who had died due to the same type of complications. Yeah I feel badly for DH, but I also feel badly for his mom, I know in my heart she feels bad about what happened to her son, that he was in fact hurt from this unnecessary surgery. I know my MIL and I know that in her heart she felt like it was the best thing to do for her sons because that's what the medical "norm" was at the time.
I am proud of my DH, he trusted that I knew the best for our son. I was concerned it would be a battle like many women have on this very sensitive subject, but *maybe* it was because he had been traumatized as a small baby and had problems it was an easier decision than for some guys, he didn't want his son to be subjected to that same thing. I mean in reality DH possibly could have died as an infant, I really don't know, but it was enough they wouldn't release him.
I guess I can't feel bad about what could have been because the decision was made so long ago. My DH and I have an enjoyable sex life, so I can't complain about the unknown.
