I'm not ttc till sept but at my annual appt a few weeks ago I asked for my hormone levels to be checked with the rest of my blood tests and it showed lower than normal T in my system (under 14 but not specific). Not sure what I'm doing that is contributing to it except maybe generally low food intake and stress/work/late nights/less sleep. But does having low T affect fertility (like low progesterone) or just sex drive?
