1. What is the Progesterone to Estrogen Ratio?

The Progesterone to Estrogen Ratio (Pg/E2) is a hormonal balance indicator that compares the levels of progesterone to estrogen in the body. It's used to assess hormonal health and balance, particularly in women's health and fertility.

2. How Does the Calculator Work?

The calculator uses the simple ratio formula:

Where:

• Progesterone — Measured in nanograms per milliliter (ng/ml)
• Estrogen — Measured in picograms per milliliter (pg/ml)

Explanation: The ratio provides insight into the balance between these two important hormones, which is often more meaningful than absolute values alone.

3. Importance of Pg/E2 Ratio

Details: The ratio is important for assessing hormonal balance, fertility status, menopausal transition, and certain endocrine conditions. An optimal ratio supports healthy menstrual cycles and pregnancy.

4. Using the Calculator

Tips: Enter progesterone in ng/ml and estrogen in pg/ml. Both values must be positive numbers. The result is a unitless ratio that indicates the relative balance between these hormones.

5. Frequently Asked Questions (FAQ)

Q1: What is an ideal progesterone to estrogen ratio?
A: Optimal ratios vary by menstrual cycle phase and life stage, but generally range between 100:1 to 500:1 in the luteal phase.

Q2: When should these hormones be measured?
A: Timing depends on purpose - day 21 for luteal progesterone, day 3 for baseline estrogen in menstrual cycles.

Q3: What does a low ratio indicate?
A: May indicate estrogen dominance or insufficient progesterone production, associated with certain symptoms and conditions.

Q4: What does a high ratio indicate?
A: May indicate progesterone excess or estrogen deficiency, which can also cause symptoms.

Q5: Are there limitations to this ratio?
A: Yes, it doesn't account for hormone receptor sensitivity or other hormones that influence the endocrine system.
