During testosterone therapy, total and free estradiol (the main form of estrogen) levels increase dose-dependently in both young (aged 19-35 year old) and 52 older (aged 59-75 year old) men, and more so in older men compared to younger men.
The potential clinical consequences of higher estradiol levels and higher estradiol-to-testosterone ratios in older men remains poorly understood, and the optimal management of high-normal or elevated estrogens is controversial among clinicians.
Interestingly, in some patients, an initial elevation in estradiol is followed by decreased estradiol after prolonged testosterone therapy.[3, 4] This may be due to reduced body fat mass or decreased testosterone levels over time with fixed dose treatments.
Here you will get advice on how to best approach estrogen management while on testosterone therapy…
