New Ways to Test Ovarian Reserve

Research shows combining antral follicle count (AFC) with day 3 FSH and age improves ovarian reserve assessment. Younger patients with elevated FSH can still achieve good pregnancy outcomes with aggressive stimulation. A 30-year-old with FSH 14 has better prognosis than a 40-year-old with FSH 7.


Key Takeaways

Combining AFC and Day 3 FSH with Age for Accurate Ovarian Reserve Assessment

Integrating antral follicle count (AFC), day 3 FSH levels, and patient age provides a more accurate fertility prognosis than relying on FSH alone. For example, a 30-year-old with elevated FSH (14) has better outcomes than a 40-year-old with normal FSH (7), highlighting age as a critical factor.

Younger Patients with Elevated FSH Benefit from Aggressive Ovarian Stimulation

Younger women with moderately elevated day 3 FSH (e.g., 14) can achieve reasonable pregnancy rates with more aggressive IVF protocols. Studies show they respond better to higher stimulation doses, even with lower egg counts, due to preserved egg quality.

Older Patients with Elevated FSH and Low AFC May Require Donor Egg Consideration

Women over 35 with both elevated day 3 FSH and low antral follicle count (AFC) face higher risks of chromosomal abnormalities and infertility. Data indicate donor egg treatment is statistically more successful for older patients with poor ovarian reserve metrics.
