Thanks for the update!
I was thinking about you and wondering how your appt went.
Metformin has done wonders for MANY women and can totally help balance out your hormones that get all out of whack with insulin resistance/pcos.
That on its own could be a HUGE factor in helping you out.
Combined with the gameplan of testing the RE has for you, I really think you are on your way

I hear you on the "when he's up to it" that can be a very daunting task for alot of gentlemen.
Mine was NOT super happy about it, but was surprised to find out that his normal morphology was WAY low.
A good Man's multivitamin that includes selenium and vitamin C could be a good preventative measure.
It increased my hubbys percentage from only 4% to 18%.
