Chlordecone exposure and women's fertility

KARU-FERTIL: Chlordecone Exposure and Female Fertility

Observational Centre Hospitalier Universitaire de la Guadeloupe · NCT07231510

This project will test whether past exposure to the pesticide chlordecone is linked to lower anti-Mullerian hormone (AMH) levels in women aged 18–39 who seek infertility care in Guadeloupe.

What this trial studies

The study will enroll women aged 18–39 who attend the Centre Caribéen de Médecine de la Reproduction (CCMR) at the University Hospital of Guadeloupe and obtain informed consent. Researchers will measure blood chlordecone concentrations and anti-Mullerian hormone (AMH) as a marker of ovarian reserve, and may collect samples for non-targeted environmental exposure testing and vaginal/endometrial microbiome analysis. This is an observational analysis that will look for statistical associations between chlordecone exposure and AMH while accounting for clinical and other exposure factors. Results will help clarify whether persistent environmental contamination in the French West Indies is associated with reduced ovarian reserve.

Who should consider this trial

Good fit: Women aged 18–39 who are consulting for couple infertility at the CCMR (University Hospital of Guadeloupe) and who provide free, informed, written consent.

Not a fit: Women outside the 18–39 age range, those not seeking infertility care at CCMR, or those whose infertility is clearly due to non-environmental causes may not gain direct benefit from this study.

Why it matters

Potential benefit: If a link is confirmed, the results could help identify environmental causes of reduced ovarian reserve and guide public-health actions and fertility counseling for affected women.

How similar studies have performed: Animal studies have consistently reported that chlordecone impairs ovulation and reduces ovarian reserve, but no human studies have yet directly linked chlordecone exposure to female fertility.
