Fertility Age & Egg Reserve Calculator: Your Guide to Reproductive Health

Understanding your fertility health is critical for family planning, whether you’re trying to conceive now or preparing for the future. Our Fertility Age & Egg Reserve Calculator provides a scientific, user-friendly way to estimate your reproductive potential. Let’s break down how it works, the terms involved, and how to interpret your results.

Key Terms Explained

1. Anti-Müllerian Hormone (AMH)

A hormone produced by ovarian follicles. AMH levels directly correlate with your egg reserve (the number of eggs remaining in your ovaries).

• Normal Range: 1.0–4.0 ng/mL

• Low AMH: May indicate diminished ovarian reserve

2. Follicle-Stimulating Hormone (FSH)

A pituitary gland hormone that stimulates egg maturation. High FSH levels (typically >10 mIU/mL) often suggest your body is working harder to recruit eggs, signaling reduced ovarian reserve.

3. Antral Follicle Count (AFC)

The number of small follicles visible via ultrasound at the start of your menstrual cycle. A higher AFC (10–20) indicates better ovarian reserve.

4. Fertility Age

Your biological reproductive age, which may differ from your chronological age. A 35-year-old with strong AMH/AFC could have a fertility age of 30, for example.

Why These Metrics Matter

• AMH: Predicts response to fertility treatments like IVF.

• FSH: Flags potential ovarian dysfunction.

• AFC: Provides a "snapshot" of remaining eggs.

• Age: Impacts egg quality and chromosomal normality.

How the Fertility Calculator Works

Step 1: Input Your Data

The calculator accepts:

• Age (18–45 years)

• AMH levels (in ng/mL or pmol/L)

• FSH levels (mIU/mL or IU/L)

• Antral Follicle Count

Step 2: Unit Conversions

The tool automatically converts:

• AMH: pmol/L → ng/mL (divide by 7.14)

• FSH: IU/L → mIU/mL (1:1 ratio)

Step 3: Scoring Algorithm

A proprietary formula weighs:

• AMH (40% weight)

• AFC (30%)

• Age (20%)

• FSH (10%)

Scores range from 0–10:

• 8–10 (Green): Strong reserve

• 5–7 (Yellow): Moderate reserve

• 0–4 (Red): Low reserve

Step 4: Visual Results

• Color-Coded Meter: Instantly shows risk level.

• Radar Chart: Compares your metrics against population averages.

Interpreting Your Results

High Score (Green Zone)

Likely good ovarian reserve. Ideal for delaying conception if desired.

Moderate Score (Yellow Zone)

Suggests declining fertility. Consider consulting a specialist within 1–2 years.

Low Score (Red Zone)

May indicate significantly reduced fertility. Seek immediate reproductive endocrinology evaluation.

Why Use This Calculator?

• Clinical-Grade Analysis: Based on peer-reviewed fertility markers.

• Global Accessibility: Unit conversions for international users.

• Actionable Insights: Clear next-step recommendations.

Frequently Asked Questions

Q: How accurate is the calculator?

A: It provides estimates using widely accepted biomarkers but cannot replace medical testing.

Q: Can men use this tool?

A: While male fertility options exist, this calculator focuses on female biomarkers.

Q: What if my FSH is borderline high?

A: Repeat tests—FSH fluctuates monthly. Combine with AMH/AFC for clearer insights.

Next Steps After Testing

1. Share results with your OB-GYN.

2. Consider advanced testing (e.g., ovarian ultrasound).

3. Explore fertility preservation (egg freezing) if needed.

Conclusion

Our Fertility Age & Egg Reserve Calculator demystifies reproductive health data, empowering you to make informed decisions. While no online tool replaces medical advice, it provides a critical starting point for understanding your fertility potential.
