PCOS mystery: could a pregnancy hormone be the key to inherited risk?
NCT ID NCT03483792
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study looked at 58 pregnant women with and without PCOS to understand how hormones like AMH and leptin might be passed to their babies. Researchers measured these hormones in the mother's blood during each trimester and in the placenta after birth. The goal was to see if higher AMH levels in pregnancy could explain why daughters of women with PCOS are more likely to develop the condition.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this research could help explain why daughters of women with PCOS have a higher risk of developing the condition, pointing toward potential early interventions.
- What could go wrong
- This is a small, observational study that only measures hormone levels during pregnancy. It does not test any treatment, so it cannot directly lead to a cure or therapy on its own.

In the group of female controls, the fertility problem is not related to a female pathology of the hypothalamic-pituitary-ovarian axis (tubal or male infertility). They are women without ovarian personal pathology. The problem of fertility being of other origin.
