I went on Clomid and combined with 10 - 15 lbs. put on over the course of a summer seemed to fix things.
After two years of weening off Clomid, my symptoms have remained at bay, but I'm also 19 pounds heavier still.
I would suggest purposely trying to gain weight for a few months, add at least 5 lbs. of bodyweight if not more, and see how you feel. Take it as an opportunity to crush it in the gym and enjoy yourself for a bit.
Just don't do what I did and overshoot your goal by 15 lbs. and then have to diet it off.
