Progesterone to Estrogen Ratio Calculator
Calculate P/E2 ratio for hormonal balance assessment and reproductive health evaluation
Calculate P/E2 Ratio
Normal luteal phase: 11-29 ng/mL or 35-92 nmol/L
Normal luteal phase: 19-160 pg/mL or 70-600 pmol/L
P/E2 Ratio Results
Calculation: 0.00 pg/mL ÷ 0.00 pg/mL = 0.00
Reference Range: Normal 100-500, <100 (estrogen dominance), >500 (progesterone dominance)
Ratio Interpretation Guide
Unit Conversion Reference
Progesterone
1 ng/mL = 3.181 nmol/L
1 ng/mL = 1000 pg/mL
1 nmol/L = 0.314 ng/mL
Estradiol
1 pg/mL = 3.671 pmol/L
1 pg/mL = 0.001 ng/mL
1 pmol/L = 0.272 pg/mL

Understanding Progesterone to Estrogen Ratio
What is P/E2 Ratio?
The progesterone to estradiol (P/E2) ratio is a critical measurement used to assess hormonal balance in women. It's calculated by dividing progesterone levels by estradiol levels, both measured during the luteal phase of the menstrual cycle.
Clinical Significance
- •Identifies hormonal dominance patterns
- •Predicts IVF treatment success
- •Evaluates luteal phase adequacy
- •Assesses conception probability
Calculation Method
P/E2 Ratio = Progesterone ÷ Estradiol
(Both values converted to same units)
