The calculation of testosterone to estradiol ratio, also known as T/E2, is a parameter linked to a whole spectrum of male health aspects, primarily associated with sexual functions. The values needed for the estimation are free testosterone (T) and estradiol (E2) concentrations. The calculator can also be used for converting estradiol and testosterone units of measurement.
How is testosterone to estradiol ratio calculated?
The formula itself is very simple: ratio = testosterone / estradiol
The tricky part is that before the calculation of testosterone to estradiol ratio, both hormone concentrations need to be expressed in the same units, and they’re generally presented in different ways: testosterone in ng/dL, and estradiol in pg/mL.
