PREVenting-ENvIronment-Reprotoxic Exposures Before In Vitro Fertilization (PREVENIR-FIV)

• Arm A (interventional): analysis of the responses to the self-administered questionnaires with, if necessary, protocol interview concerning environmental and occupational factors, which will determine the consultations to be planned for their follow-up by the platform. - support of couples by the multidisciplinary platform with the help of the downloaded application: Meeting by videoconsultation with professionals adapted to the exposures highlighted by the questionnaires. Multidisciplinary Synthesis (MS): Synthesis of the first consultations and the results of the self-questionnaires by the multidisciplinary team. Determination of preventive and corrective measures, specific advice, specialized follow-up if necessary. Presentation to patients of the personalized measures decided in MS: information on the personalized management proposed (follow-up addictologist, dietician, psychologist, occupational doctor), personalized advice sheets. Couples who do not require personalized measures will continue their treatment with prevention advice adapted to their profession and their environment. Transmission of the minutes of the MS to the clinician in charge of the couple.
• Arm B (standard management): care path according to the usual modalities of the ART center (indications, network of practitioners, monitoring and information tools). If necessary, distribution by the clinician of information leaflets on addictions, dietetics + distribution of a general information leaflet on reprotoxic factors.

In both arms: embryology consultation before ART: information on the planned ART. Information on the online self-assessment questionnaire for assessing reprotoxic exposures, assessing stress, physical activity, and quality of life during infertility. In centers with a biological resource center Germethèque, hair sampling from the 2 members of the couple.

First attempt of IVF/ICSI, in both arms, followed for 24 months with every 6 months: information of the online self-administered questionnaire of assessment of reprotoxic exposures, assessment of stress, physical activity, quality of life in infertility course. At 12 months and 24 months: hair sampling from both members of the couple (in Germethèque centers only).

• In arm A during the 24 months of follow-up: active support of corrective measures implemented with couples by the platform, with the help of the application (weight loss goals, changes in habits, physical activity, decreased or stopped toxics). Continuation of specialized follow-up if necessary, in videoconsultation.

At the end of the study: a sample of about twenty couples in each arm will be the subject of a semi-directed interview aimed at qualitatively determining the brakes and levers to their adherence to the environmental health advice received during their management in ART.

Medical-economic analysis: a cost-effectiveness analysis and a budget impact analysis will be carried out by the Epidemiology and Health Economics Department.
