I started taking HCG with the intention of getting my wife pregnant, we had not used birth control for some time due to me being on a long test cycle, 3 months after starting HCG 500iu twice per week she was pregnant.
It takes a sperm about 70 days to mature, so to me that is too much of a coincidence.
If I were you I would get on low dose HCG and maybe some clomid.
