    How does Thyroid hormone effect Estrogen and Aromatase?

    I have searched for the answer endlessly and only got conflicting reports . Does Thyroid hormone ( T4,t3) reduce Estrogen or raise it ? What is their effects on the aromatase enzyme ? Thank you .

    Question about t3 and t4

    If t3 is the active thyroid hormone, then what would be the point of even taking t4? I ask because I have been on t3 only treatment since beginning HRT due to high RT3. Wondering if I could benefit from adding in a little t4 to my protocol. T4 is usually at the bottom end of normal or just...

    How many of you are on thyroid meds?

    And what made you take the leap? Classic low TSH/T4 or T3? I see some of you are having reverse T3 measured which I believe isn't standard practice.

    Why do i need to keep increasing my t4 and t3 dose? Endogenous production?

    it seems like after a dose increase i get my levels balanced (t4,t3) but then slowly my levels fall again. I am guessing that it is because endogenous production reduces due to a negative feedback loop similar to that of testosterone? Does my endogenous production have to be completely shutdown...

    I recently had to take a break in treatment for 5 maybe 6 weeks due to my Endo switching clinics. Before she would prescribe my meds she wanted to run more blood work. These results showed my total and free levels normal but my FSH and TSH w/reflex to t4 was high. So she wants me to stop...

    T3, T4 and SHBG

    I read that thyroid meds can increase SHBG. Questions: 1. I have not found definitive info if it is the T4 in the meds or the T3 or both that cause this effect? 2. Is there any info on dose-response of Thryoid on SHBG? I'm being treated for hypogonadism (Cypionate 200mg/weekly +...
