I'm so sorry you are dealing with this - it is so difficult dealing with any aspect of infertility. I know I am not in the same exact position, but I think if this is something you still want to pursue, that you aggressively look into what your other options are and come up with a new plan. It's so much easier said than done, but be easy on yourself and remind yourself that our bodies sometimes fail us in unexpected ways and although aggravating and absolutely maddening, be kind to you and stick together with your wife through this. Speaking out here and maybe other therapy to cope will be beneficial to help you get your thoughts in a better place to move forward to whichever path you choose. The healing doesn't happen over night even tho I want it to for all of us. Wishing you all the best!

This is really hard, and although I may not know what it feels like, my husband and I are having difficulty conceiving due to MFI. I am not going to sugarcoat it, when we first found out, I was devastated and so angry - not at him, rather just the world in general. Even now, at my lowest points, there is no one that I would rather go through life with, or have children with (biological or adopted), than him! Try to be good to yourself and be honest with your wife with how you are feeling, always. We have had some very sad and rough conversations where we both feel defeated and disappointed, but in the end, we know that the strength of our love and marriage will get us through. You will get through this!

Im so sorry to hear this. We are also struggling and it is due to the morphology of my partners sperm. We are going for a second opinion to rule out completely that he cant have a biological child. We have discussed at length what that would mean for us and he knows how deeply I want to be a mother and he wants to be a father. To him if the only way we can have a family, a child etc is the sperm donor route, is the road he is wanting and willing to take with me. I said we would look for his similar features that we can and as far as we are concerned people who are not family etc they will never have to know that biologically that child is not his. He will be that babies dad no matter what.. the same genetics and blood does not automatically make you a father; its what you do after that baby comes into this world and how you raise your daughter/son. Also the only reason our families would know is because they have been our support and we have been 100% forthcoming with everything going on. I know its not the ideal route not having bio children, but as I said for all intents and purposes that child would know my partner as their dad and that too me and to my partner is all that matters.
I am truly sorry as it is a hard path to go down and you have to remember... this is not your fault.. beating yourself up isnt going to change it - if your comfortable explore other ways so you can become a father and your wife a mother.

It is refreshing to have a male perspective on this community as in my experience so far it's rare. It really speaks to the strength of yours to reach out for support, and how amongst receiving devastating results your concern is how to support your wife. I am sad for you, and hopeful you will explore other options when you are ready.
We are struggling with conceiving a child, and after several years got testing back that my partner's sperm 'dna fragmentation' was in the very low range, meaning his chances of having a bio child were very low and the most devastating news was that it eliminated IVF as an option - that was my cushion or go to plan if we continued to struggle. In response to your question, how to best support your wife, I'll share with you my perspective, from my own experience. Validate your own and her feelings, share how you feel with each other, and be compassionate and affectionate with each other. My partner deals with stress in the opposite manner (avoids, retreats, bottles up) and also shuts down my emotions and invalidates my feelings. I felt a need to be open and expressive about the loss of being able to have a bio child with him, without it being perceived as a I was attacking him. It made it very difficult to process what news we just got dealt and felt unsafe discussing potential options for having a baby. We are working on this, and improving slowly. It's so difficult.
I am happy to say we had some positive news however, that his recent sperm sample had significantly improved (we believe it was lifestyle and stress he was under when his dad was passing away from cancer at the time his sperm would have been created). We were thrilled with the positive news, and now are feeling a crunch age-related to move on things fast.
Wishing you all the best for you and your wife through this journey.
