Understanding T/E2 Ratio
What is T/E2 Ratio?
The testosterone to estradiol ratio (T/E2) is a biomarker that reflects the balance between these two important hormones in men. It's calculated by dividing testosterone levels by estradiol levels when both are expressed in the same units.
Clinical Significance
- •Associated with cardiovascular health in men
- •May influence sexual function and libido
- •Related to fertility and reproductive health
- •Potential marker for metabolic health
Calculation Method
T/E2 Ratio = Testosterone ÷ Estradiol
(both values in same units)
Important Notes
- ⚠No established "normal" ratio range exists
- ⚠Both individual hormone levels should be normal
- ⚠Unit conversion is critical for accurate calculation
- ⚠Clinical interpretation requires medical expertise
Example Calculation
Sample Values
Given:
Testosterone: 600 ng/dL
Estradiol: 30 pg/mL
Step 1: Convert to same units (pmol/L)
T = 600 × 34.66 = 20,796 pmol/L
E2 = 30 × 3.6713 = 110.1 pmol/L
Step 2: Calculate ratio
T/E2 = 20,796 ÷ 110.1 = 188.8
