Well, my total Testosterone level was at 99 ng/dL back in November so she had me up my daily dosage by 20%.
Two and a half months later my lab showed me at 37 ng/dL on the slightly higher dosage (perfect if you ask me).
My last lab in March had my level at 25 ng/dL (which seemed like a normal fluctuation from the 37 to me), and she had me drop the extra 20% of Spiro because she felt this was too low.
The Quest Diagnostic range for females is 2-45, so I can only assume she thought the lower level was somehow affecting my libido.
I've been on the lower Spiro dosage for 6 weeks now (I'm assuming my level is probably back to around 99 again) and my sex drive has not improved... much to the detriment of my relationship.
I think the only effect it's had on me is making my leg and facial hair grow a little bit faster again.

Now I've read where some doctors wait to prescribe progesterone until after 1-2 years of Estradiol, as it somehow may mark the end of breast growth. But, I have also met at least one girl that had both Estradiol and Progesterone prescribed right from the beginning of her HRT.
I know some of you are post-op so I assume you've been on HRT for several years.
I'm a 34-36 B bra size right now but my breasts are still tender, so I am assuming they're still growing.
Can I ask where you were in your transition when you added Prometrium?
I have been taking Spiro and Estradiol for almost 10 months now. I wan't to consider the possible unintended effects of taking Prometrium now, before I lobby my doctor for some (again).
Sorry for all the questions, but you girls seem to be very knowledgeable and experienced in this area, and I really appreciate your help here.
