1. What is the Pg/E2 Ratio?

The Pg/E2 (Progesterone to Estradiol) ratio is a hormonal marker used to assess the balance between progesterone and estradiol levels in the body. This ratio is particularly important in evaluating hormonal health, fertility status, and menstrual cycle regulation.

2. How Does the Calculator Work?

The calculator uses the Pg/E2 ratio formula:

Where:

• \( Progesterone \) — Progesterone level in pg/mL
• \( Estradiol \) — Estradiol level in pg/mL

Explanation: The equation calculates the simple ratio between progesterone and estradiol levels, providing insight into hormonal balance.

3. Importance of Pg/E2 Ratio Calculation

Details: The Pg/E2 ratio is crucial for assessing hormonal balance, evaluating fertility potential, monitoring hormone replacement therapy, and identifying potential hormonal imbalances that may affect overall health.

4. Using the Calculator

Tips: Enter progesterone and estradiol values in pg/mL. Both values must be valid (greater than 0). For accurate results, use lab values obtained from the same blood draw.

5. Frequently Asked Questions (FAQ)

Q1: What is a normal Pg/E2 ratio?
A: Normal ratios vary throughout the menstrual cycle and between individuals. Typically, a ratio between 100:1 and 500:1 is considered normal in the luteal phase, but consult with a healthcare provider for personalized interpretation.

Q2: When should I test my progesterone and estradiol levels?
A: Timing depends on your purpose. For cycle evaluation, progesterone is best measured 7 days post-ovulation, while estradiol can be measured at different cycle phases depending on the clinical question.

Q3: Can this ratio help with fertility assessment?
A: Yes, the Pg/E2 ratio is often used in fertility evaluations to assess whether hormonal balance supports implantation and pregnancy maintenance.

Q4: Are there limitations to this ratio?
A: The ratio should be interpreted in clinical context alongside other hormones and symptoms. It varies throughout the menstrual cycle and may be affected by medications, stress, and other factors.

Q5: Should I fast before hormone testing?
A: Fasting is typically not required for sex hormone testing, but follow your healthcare provider's specific instructions for accurate results.
