Impact of Oocytes With CLCG on ICSI Outcomes and Their Potential Relation to Pesticide Exposure — CLCG-ICSI  

Pesticide Poisoning Clinical Trial

Official title: Impact of Oocytes With CLCG on ICSI Outcomes and Their Potential Relation to Pesticide Exposure

Status Completed

Clinical Trial Summary

Oocyte quality is a key limiting factor in female fertility which is primarily reflected in morphological features. Centrally located cytoplasm granulation (CLCG) is one type of cytoplasmic dimorphism exhibited by oocytes that could be linked to pesticide exposure with a significant risk of decreased ICSI outcomes.

This retrospective study included 633 women who were part of an intracytoplasmic spermatozoa injection (ICSI) program between 2009 and 2011. The participants lived in the Picardy region of France and had been exposed to pesticides. The participants were divided in two groups based on prevalence of oocytes with CLCG (LCLCG [n= 83]: low prevalence of oocytes with CLCG under 25%. HCLCG [ n= 68]: high prevalence of CLCG over 75%). The embryological and clinical outcomes were analysed for both groups and were calculated using the difference between the two values.

The embryological and clinical outcomes were analysed for both groups and were calculated using the difference between the two values. The included population in the investigator's retrospective study consisted of 633 couples who attended a reproductive medical center and who were part of an ICSI program between 2009 and 2011. ;
