Age and Fertility: How Your 20s, 30s, and 40s Impact Pregnancy Chances

Fertility declines steadily after age 25, with 3.4% live birth rates for women 43-44 using their own eggs versus 56.7% for donor egg cycles. Shady Grove Fertility’s data shows age-driven treatment shifts, including increased IVF use after 35 and donor egg reliance in the 40s.

Key Takeaways

Peak Fertility in 20s and Steep Decline After 35

Women’s fertility peaks in their 20s, with a gradual decline in the 30s. By age 45, natural conception becomes unlikely for most due to biological aging of eggs.

SART Data Validates Shady Grove’s Superior Success Rates

Shady Grove Fertility’s live birth rates for women 38-40 using their own eggs (via IVF) and donor egg cycles significantly outperform national averages, with lower multiple pregnancy risks.

Age-Driven Treatment Strategies: IUI vs. IVF

Younger women (20s-30s) may start with IUI (20% per-cycle success) before progressing to IVF, while women over 35 are advised to prioritize IVF earlier due to time-sensitive fertility declines.

Donor Eggs Offer 56.7% Live Birth Rates for Women Over 40

Using donor eggs can raise live birth rates to 56.7% for women of all ages, compared to 3.4% for 43-44-year-olds using their own eggs, making it a critical option for older patients.

40s Patients Rely on Donor Eggs for Higher Success

Women in their 40s are more likely to use donor eggs (vs. their own) due to age-related egg quality decline, with Shady Grove’s data showing this approach dominates treatment cycles in this age group.
