I don't know about your specific case 'cuz I'm not on T yet. However, I did have all periods stop, randomly, for 6 straight months... I was happy about this 'til I read that it could lead to osteoporosis (which runs in my family anyways), so to the doc I go. She suggested putting me on 'female hormones'--aka progesterone & estrogen--an idea that I balked at, so she said I could just try the progesterone at first to see if it worked. I took the prescription but didn't fill it for 2 months (doc said it would be ok to wait that long); at the end of the 2 months I had the progesterone filled, took it & nada. A month later, when I finally got the guts to put myself through the dreaded E as well (HOW had I not come out to myself at this point?!), well... it worked.
Anyways, my guess is a dose of estrogen, or progesterone, or both, prolly in a fairly large amount to counteract the larger amounts of T in your system; but I'm sure if you called the doc's office he could tell you what he would be using so you could research it more.
