Hi Stella,
I conceived very quickly as well, so I asked the Microsort dr. if that would increase my odds at being successful with IUI. He said that it couldn't hurt, but they had no statistics to show that it would be any easier for me that anyone else. The issue is that the dh sperm get spun and goes from something like 300million all the way down to a few hundred thousand. So they are really doing major major changes to the sperm. You are basicly trying to get pregnant with the lowest sperm count imaginable. The dr. stands by his 17% chance of getting pregnant.
I am still considering whether to do it and I just can't decide. But if you look at it this way: You have a 17% chance of conceiving each time. About 30% of people concive within 4 tries. So if you are one of that 30%, you get a conception for your $16,000. But then you have a 20% chance of miscarriage, which is the same rate as normal pregnancy. And then, for us, we will have a 72% chance of having the boy that we want. It makes me wonder if our 50% chance of conceiving a boy naturally might be better odds!
Let us know what other info you find or what decision you decide to go with,
