Hi H,
Firstly, sorry to hear this.
When my DH and I found out we would require IVF due to Male Factor Infertility he was so down on himself.
He blamed everything on himself and said he felt like a failure because he couldn't deliver what we wanted so much.
It broke my heart. Basically I just reassured him everytime we talked about it. I always refer to it as 'our' infertility. I sat down with him one day and just told him it was no-ones fault and asked how he would feel about me if it was my eggs that were the issue. Made him see sense.
He has come around and we are going through IVF currently and he has been amazing.
Also, get your Mr. on some Menevit I have heard that can do wonderful things for quality & count. It takes around 3 months to kick in though so start it A.S.A.P. Maybe get him to take it the same time you take your folic acid so once again it feels like a 'joint' thing!
Ha ha I feel like a Mama already!
Good luck!
