So today I've been for a hsg, I'd done abit of research before I went to see how painful it really was, if at all.. Turned out that for me it was quite painful and I went all faint... Breathing exercises dont help when you have a mask on. Anyway the doctor told me that im all fine and we have unexplained infertility and our next step now is to go for ivf, however my partner hasn't stopped smoking and she said that he HAS to before we can be referred.. Ive told him this and he doesnt seem to be taking it seriously or am I being silly? All he's done so far is had to give a sperm sample whereas ive had numerous blood tests, ultrasounds and the hsg. I dont know how to approach this with him, do I tell him outright to quit??. The doctor is ringing me in a few weeks to check he's stopped. If he hasnt and I lie, can the ivf clinic tell he's still smoking??
