1. What is the Progesterone Estrogen Ratio?

The Progesterone to Estrogen (P/E) Ratio is a measure of hormonal balance between progesterone and estrogen levels in the body. It provides insight into the relative dominance of these two important hormones.

2. How Does the Calculator Work?

The calculator uses the simple ratio formula:

Where:

• \( P \) — Progesterone level (ng/ml)
• \( E \) — Estrogen level (pg/ml)

Explanation: The ratio compares the absolute levels of progesterone to estrogen, with higher values indicating relative progesterone dominance and lower values indicating relative estrogen dominance.

3. Importance of P/E Ratio

Details: The P/E ratio is important for assessing hormonal balance, which affects menstrual cycle regularity, fertility, mood, and various aspects of women's health. An optimal ratio is typically between 100-500 in the luteal phase.

4. Using the Calculator

Tips: Enter progesterone in ng/ml and estrogen in pg/ml. Both values must be positive numbers. For most accurate results, testing should be done during the luteal phase (day 19-22 of a 28-day cycle).

5. Frequently Asked Questions (FAQ)

Q1: What is a normal P/E ratio?
A: Optimal ratios vary by menstrual cycle phase. In the luteal phase, 100-500 is generally considered optimal, while values below 100 may indicate estrogen dominance.

Q2: How do I interpret my ratio?
A: Higher ratios indicate progesterone dominance, lower ratios suggest estrogen dominance. Interpretation should be done in clinical context with a healthcare provider.

Q3: When is the best time to test?
A: For cycling women, day 19-22 of a 28-day cycle (luteal phase) when progesterone should be at its peak.

Q4: Does this apply to menopausal women?
A: The ratio can still be calculated but interpretation differs as both hormones decline after menopause.

Q5: Can this ratio be used for men?
A: While men do have these hormones, the ratio is primarily used in female hormone assessment.
