OBJECTIVE: To examine the association between serum antimüllerian hormone (AMH) and live birth among women aged ≥41 years undergoing in vitro fertilization (IVF).
DESIGN: Retrospective cohort study using the 2012-2014 Society for Assisted Reproductive Technology Clinic Outcome Reporting System database.
SETTING: Fertility clinics reporting to the Society for Assisted Reproductive Technology.
PATIENTS: The analysis included 7,819 patients aged ≥41 years who underwent a first fresh, autologous IVF cycle during the study period. Cycles with preimplantation genetic testing were excluded.
INTERVENTIONS: None.
MAIN OUTCOME MEASURES: Live birth rate.
RESULTS: The empirical distribution of AMH was examined, and extreme values were observed. Therefore, the natural logarithm transformation of AMH (log-AMH) was used in all analyses. Before adjustment for covariates, a one-unit increase in log-AMH was associated with doubling of the odds of live birth up to a log-AMH of -0.34 (equivalently, AMH, 0.71 ng/mL; odds ratio [OR], 2.02; 95% confidence interval [CI], 1.66-2.46). Above an AMH level of 0.71 ng/mL, the odds of live birth increased by only 40% with each unit increase in log-AMH (OR, 1.40; 95% CI, 1.22-1.61). After adjusting for covariates, the odds of live birth increased by 91% with each unit increase in log-AMH up to -0.34 (AMH, 0.71 ng/mL; OR, 1.91; 95% CI, 1.56-2.34). Above an AMH level of 0.71 ng/mL, the odds of live birth increased by only 32% with each unit increase in log-AMH (OR, 1.32; 95% CI, 1.15-1.53).
CONCLUSIONS: Among women aged ≥41 years undergoing fresh, autologous IVF, the odds of live birth significantly increase with increasing serum AMH level. As the AMH level increases above 0.71 ng/mL, the association maintains statistical significance, but the effect size is diminished.
