We have severe male factor too. There aren't any known issues on my end, but like many of you, I do wonder. ART hasn't been successful for us yet (frozen donor sperm w IUI x 3, fresh donor w ICI x 1). At one point, my partner told me he didn't want children at all, in the midst of everything. I almost left him. It was a hellish period in our relationship as well as for each of us personally. In the end, it isn't that he doesn't want children, but that, at that point in time, the process of "getting" children was too much for him. I still feel a little decieved though. We talked about children before we talked about so many other important things. We got married with the understanding and with plans that we would have 4 or 5 kids. Now, I may never get to experience pregnancy or birth. I do resent him a little bit for that. I occasionally think about cheating on him. I won't, but sometimes it's appealing.

In the end though, I have been blessed with my partner. He is hyper aware of the potential for bitterness and resentment and does everything he can to minimize it. I love him, we're still going to parent together. We're in a good place now.
That said, I do think that men just don't typically get as involved with fertiilty stuff in terms of researching, etc. I think part of it is that a baby is real to a man when it appears, or maybe when he can feel it moving inside his partner. Maybe. All this prep stuff could feel a bit disconnected, maybe? I also know that, while my partner is open to taking the supplements I pump him full of, I have to research them, purchase them, and then put them in his hand with a glass of water. He basically takes them to placate me. He feels that his sperm is so bad, what good is it to try to make them a little bit better, when a bit better still isn't good enough? Maybe this is a shared thought process?
I did completely lose it at him not too long ago when he had to update his SA. You have to do something pleasant and collect the results. That's it. Perhaps a little embarassing to drop it off, but seriously?!? I had to twist his arm to get him to do it and he complained the whole time. Eventually I just let him have it with the, "I have to have catheters inserted into my closed cervix, numerous people spend time looking at my splayed open genitals, I have to get poked and prodded and measured and tested constantly. And there is nothing wrong with me. All you have to do is ejaculate into a cup!" There were a few other things in there, but that was the general theme. It got him moving.

I still feel bad about saying those things though. He didn't chose to have a body that doesn't co-operate. Sometimes that helps me, if I can just remember that, just as I didn't chose this situation, neither did he. In a way, I feel a bit lucky that he is the problem. I don't know if I could handle knowing that it is entirely my own body that is keeping the one thing I want most from me. At least there are options when it's male factor.
You're allowed to be bitter, really. You're allowed to feel anything you need to. Infertility sucks. Just try not to let it take over.
Best,
