Low testosterone? Sorry, long post :)

I posted about this in the general room but didn't get any responses, so I thought I would try again. Did anyone's hubby find out they have low testosterone? If so, what did you guys do about it? We found out about a month ago at hubby's primary doc, who doesn't know we're ttc. So, he wants to recheck levels after watching diet and exercise, even though hubby has always exercised regularly.

We got pregnant twice, very quickly, but miscarried twice. I told my (new) OBGYN but she didn't think it was a big deal (she was thinking about the miscarriages). But, I know that Low T can go hand in hand with low sperm count. We got pregnant so quickly twice (2 months both times) and now it's been 6 months since our last loss. It seems like his T may have dropped within the last several months, and that worries me. Thanks ladies!
