1. What is the Hormone Level Equation?

The hormone level equation estimates typical estrogen or progesterone levels based on age and menstrual phase. It provides a general reference range that accounts for normal age-related changes in hormone production.

2. How Does the Calculator Work?

The calculator uses the hormone level equation:

Where:

• \( Base \) — Typical hormone level for the selected phase (pg/ml)
• \( Age\ Factor \) — Adjustment factor based on age (unitless)

Explanation: The equation accounts for gradual decline in hormone production with age, with different base values for different menstrual phases.

3. Importance of Hormone Level Calculation

Details: Understanding typical hormone levels helps assess hormonal balance, identify potential imbalances, and guide treatment decisions for conditions like menopause or fertility issues.

4. Using the Calculator

Tips: Enter age in years, select hormone type and menstrual phase. For postmenopausal women, select "menopause" phase.

5. Frequently Asked Questions (FAQ)

Q1: What are normal estrogen levels?
A: Normal estrogen varies by phase: 30-100 pg/ml (follicular), 150-400 pg/ml (ovulation), 50-150 pg/ml (luteal), <30 pg/ml (menopause).

Q2: What are normal progesterone levels?
A: Normal progesterone varies by phase: 0.1-1.5 ng/ml (follicular), 0.2-1.5 ng/ml (ovulation), 2-30 ng/ml (luteal), <1 ng/ml (menopause).

Q3: When should hormone levels be tested?
A: Testing timing depends on menstrual cycle. Estrogen is often tested on day 3, progesterone in luteal phase (day 21).

Q4: Are there limitations to this calculator?
A: This provides general estimates only. Actual levels vary by individual, health status, medications, and lab methods.

Q5: How does age affect hormone levels?
A: Hormone production typically declines with age, especially during perimenopause and menopause for women.
