Are your two daughters with your husband or another partner?
So you never had a child with your current partner? He needs a semen analysis. 50% of infertility is male. It's likely that he is the one with the issue.
Yes. Your primary md can request a semen analysis from the lab at the hospital.
I have no idea what you are asking. Similar analysis? No. It's called a semen analysis.
No not now. You have two children. I'm assuming he has none. There's no point in getting invasive testing done on yourself when it's very clear that he may have issues.
