Wow, that is a pretty low level of estradiol and you say your having feminization? That's very interesting. My blood work before start none estradiol was at 49, which is high for a male, but low for a female and my testosterone was at 241, which is at the very bottom of the normal level for male and that's even before starting estradiol or spiro, I don't know if it's cause for concern or not the person to ask would be your doctor. I certainly hope you're seeing an endocrinologist. I wish you nothing but the best of luck on your journey in May, the Angels always look upon you and guide you on your path.
