Ovarian Reserve & Biological Clock: When to Freeze Eggs?

Ovarian reserve determines biological clock time, with peak egg quantity in early 30s. Egg freezing preserves fertility, with optimal timing before 36. Testing via ultrasound and blood work assesses reserve, available at Shady Grove Fertility for $325.

Key Takeaways

Ovarian Reserve Declines with Age, Peaks in Early 30s

Women are born with 1–2 million eggs, but only ~400,000 remain by puberty. By menopause (48–55), follicles either vanish or become nonviable. Peak ovarian reserve occurs in early-to-mid 30s, making this the optimal time for egg freezing.

Egg Freezing Pauses Biological Clock, Best Before 36

Freezing eggs at higher quality (when ovarian reserve is strong) preserves fertility. Shady Grove Fertility reports a trend of women now freezing at 36 (vs. 38 in 2012), as later cycles may require multiple retrieval attempts to collect sufficient mature eggs.

Antral Follicle Count (AFC) Ultrasound Accurately Measures Ovarian Reserve

A vaginal ultrasound counts antral follicles to estimate remaining eggs. Combined with age, this is the most reliable predictor of ovarian reserve and egg freezing outcomes. Low AFC indicates diminished reserves, while high AFC suggests robust egg quantity.

Day 3 Hormone Blood Test Reveals Egg Quality & Quantity

Testing FSH, LH, E2, and AMH on day 3 of your cycle provides hormonal insights: high FSH/E2 may signal low reserve, while AMH levels directly correlate with follicle count. These metrics assess ovarian health and guide egg freezing decisions.

Ovarian Reserve Testing Costs $325 with Potential Insurance Coverage

Shady Grove Fertility offers $325 testing (including ultrasound + blood work) for ovarian reserve. 90% of insured patients receive full/partial coverage. Results during two 1-hour appointments help determine if egg freezing is viable based on egg quantity/quality.
