Aayla, was it a basic SA - count, morphology, motility? Mine came out as superman in that too. It was only just prior to starting IVF that they did an extended semen analysis and that showed 73% antisperm antibodies and we needed ICSI.
I'd always tell people to get that checked first now.
Weight is a big factor, I know. It's so hard because losing weight is difficult and time consuming. Have you heard of OA? It's a 12 step program like AA but for food addictions and eating disorders. I know lots of people who gave found it really helpful. I joined it when I was anorexic and it did help me emotionally, though I felt rather out of place at my size back then.
