Understanding Your Fertility: A Comprehensive Guide to Reproductive Health

What Is Fertility and Why Does It Matter?

Fertility refers to the natural ability to conceive a child. While often taken for granted, reproductive health depends on complex biological processes in both men and women. Tracking fertility indicators helps:

• Identify potential conception challenges

• Optimize family planning decisions

• Detect early signs of hormonal imbalances

• Guide conversations with healthcare providers

Key Terms Explained

1. Age-Related Fertility Decline

Women’s egg quality decreases sharply after 35, while men experience gradual sperm quality reduction after 40.

2. Body Mass Index (BMI)

Weight-to-height ratio impacts hormone production. Ideal BMI for conception: 18.5–24.9.

3. Ovulation Cycle

The 6-day fertile window (5 days before + day of ovulation) is critical for conception.

4. Sperm Count

Healthy sperm concentration: ≥15 million per milliliter.
