IMPACT OF POLYCYCLIC AROMATIC HYDROCARBONS (PAH) ON IN VITRO FERTILIZATION

Assistance Publique Hopitaux De Marseille220 enrolled

Overview

The main objective of this study is to highlight a relationship between exposure to PAHs, genotoxic effect biomarkers on spermatozoa and follicular cells, as well as embryonic quality and embryo implantation rates at a given time. IVF attempt. This study therefore analyzes the possibility of using this exposure biomarker as a reliable means of evaluating the quality of gametes in order to estimate the chances of success in IVF.

Objective assessment of the effect of environmental and occupational factors on fertility is difficult to establish due to the lack of relevant exposure biomarkers for reporting multi-exposures. The main objective of this study is to highlight a relationship between exposure to PAHs, genotoxic effect biomarkers on spermatozoa and follicular cells, as well as embryonic quality and embryo implantation rates at a given time. IVF attempt. This study therefore analyzes the possibility of using this exposure biomarker as a reliable means of evaluating the quality of gametes in order to estimate the chances of success in IVF. Subsequently, the results of this study will make it possible to personalize and evaluate the effectiveness of the preventive measures put in place upstream of the MPA route by allowing To identify a relationship between PAH exposure and sperm DNA gamete quality in humans, serum AMH concentration and ovarian response to gonadotropic stimulation for IVF in women. To highlight a relationship between individual exposures to complex PAH mixtures and infertility. The methodology based, on the feminine side, on the analysis of follicular cells makes it possible to study cells close to female gametes within the cumulo-oocyte complex, without losing the chance of pregnancy for the couple.

Outcomes

Primary Outcomes

expired CO

The night before the IVF, a urine sample will be collected from both members of the couple, according to the protocol published by the team Partner 2. On the day of the IVF, a measurement of the exhaled CO rate will be carried out by the two members of the couple according to the recommendations of the manufacturer.
