Testosterone to Estradiol Ratio Calculator
HealthCalculate the testosterone-to-estradiol (T/E2) ratio from serum testosterone (ng/dL) and estradiol (pg/mL) lab values. A reference calculation, not a diagnosis.

What is a T/E2 Ratio?
The Testosterone to Estradiol Ratio Calculator computes the T/E2 ratio from serum testosterone (ng/dL) and estradiol (pg/mL) values, converting units appropriately before dividing. This is a standard lab reference calculation, not a diagnostic tool.
For a related hormone ratio tool, see the Progesterone to Estrogen Ratio Calculator.
How to use this T/E2 Ratio calculator
- Enter your testosterone value in ng/dL.
- Enter your estradiol value in pg/mL.
- Read the T/E2 Ratio instantly.
- Discuss any specific lab results with a qualified healthcare professional for proper interpretation.
Formula & Methodology
T/E2 Ratio = (Testosterone [ng/dL] × 10) ÷ Estradiol [pg/mL] Worked example — a testosterone of 500 ng/dL and estradiol of 25 pg/mL: T/E2 Ratio = (500 × 10) ÷ 25 = 200
Frequently Asked Questions
The T/E2 ratio compares testosterone and estradiol hormone levels, sometimes referenced in men's hormone balance discussions as one data point among several considered together.
Testosterone is commonly reported in ng/dL while estradiol is commonly reported in pg/mL — since these are different units, converting testosterone to pg/mL by multiplying by 10 allows a directly comparable ratio.
The calculator converts testosterone from ng/dL to pg/mL by multiplying by 10, then divides that figure by the estradiol value in pg/mL.
No — this calculator performs the mathematical conversion and ratio only. Interpreting what a specific T/E2 ratio means for your health requires a qualified healthcare professional reviewing your complete hormone panel and clinical history.
Both are measured through blood tests, commonly ordered together as part of a hormone panel when evaluating men's reproductive or endocrine health.
Men produce estradiol through the conversion (aromatization) of testosterone, and measuring it alongside testosterone gives a fuller picture of the hormone balance, which is why the two are sometimes evaluated together.
The [Sperm Analysis Calculator](/sperm-analysis-calculator/) evaluates semen parameters directly, while this calculator focuses on a hormone ratio sometimes considered in the broader context of male reproductive health.
Yes — testosterone in particular is known to follow a daily pattern, often higher in the morning, so the timing of blood draws is an important context factor for interpreting any result including this ratio.
This calculator provides the ratio calculation only, without a specific threshold interpretation — any consideration of what a specific value might suggest should come from a qualified healthcare professional.
Both calculators perform a similar unit-conversion-then-ratio calculation, but the [Progesterone to Estrogen Ratio Calculator](/progesterone-to-estrogen-ratio-calculator/) is typically referenced in different contexts, often related to female reproductive hormone balance.
