Antimüllerian hormone (AMH) levels and body mass index (BMI) are both known to influence pregnancy outcomes in polycystic ovary syndrome (PCOS) women undergoing in vitro fertilization (IVF).

Key take away

Overweight or obese women with PCOS and high AMH levels face a significantly increased risk of miscarriage and ovarian hyperstimulation during IVF.

Background

Antimüllerian hormone (AMH) levels and body mass index (BMI) are both known to influence pregnancy outcomes in polycystic ovary syndrome (PCOS) women undergoing in vitro fertilization (IVF). This study monitored how different combinations of AMH levels and BMI affect pregnancy outcomes in women with PCOS undergoing IVF.

Method

This post hoc secondary analysis was based on data from a multicenter randomized trial. Overall, 625 participants from a single center, all of whom had AMH levels assessed before starting IVF, were divided into 6 groups:

  • Group A: Normal weight with low AMH
  • Group B: Normal weight with intermediate AMH
  • Group C: Normal weight with high AMH
  • Group D: Overweight/obese with low AMH
  • Group E: Overweight/obese with intermediate AMH
  • Group F: Overweight/obese with high AMH

Result

Multivariate logistic regression revealed that those in Group F (overweight/obese with high AMH) had a markedly higher risk of clinical pregnancy loss whem compared to Group B, with an adjusted odds ratio (aOR) of 3.30. Additionally, the risk of ovarian hyperstimulation syndrome was increased in both Group C (aOR 3.74) and Group F (aOR 3.61) relative to Group B.

Conclusion

Among women with PCOS undergoing IVF, elevated AMH levels were linked to a higher risk of clinical miscarriage in those who were overweight or obese, but not in those with a normal BMI.
