Summary

Chlordecone is an organochlorine pesticide used in the French West Indies (FWI) from 1972 to 1993 to control the banana root borer. Due to its very long persistence the population continues to be exposed to this chemical through their food consumptions. Although, chlordecone have been associated in animal study impairment of ovarian reserve, to date, no study has been published concerning the link between chlordecone exposure and female fertility. The main objective of this project is to study the association between chlordecone exposure and anti-mullerian hormone (AMH) in women consulting for couple infertility in Guadeloupe.

Detailed description

Chlordecone is an organochlorine pesticide used in the French West Indies (FWI) from 1972 to 1993 to control the banana root borer. Due to its very long persistence the population continues to be exposed to this chemical through their food consumptions. Chlordecone is an endocrine-disrupting chemical with well-defined estrogenic and progestagenic properties in vivo and in vitro. To date, no study has been published concerning the link between chlordecone exposure and female fertility. Nevertheless, mammalian studies in females have consistently reported that chlordecone exposure impairs ovulation and leads to a reduced ovarian reserve. In addition, there are questions about the impact of other environmental exposures, including by non-targeted approaches, and also of the vaginal and endometrial microbiome on female fertility.
