What this trial studies

This observational study aims to analyze the effects of various environmental agents, such as bisphenols, ethynylestradiol, and glyphosate, on female fertility. Women undergoing in vitro fertilization (IVF) at the University Hospital of Tours will be recruited to provide blood, urine, and follicular fluid samples, alongside completing a lifestyle questionnaire. The study will assess the relationship between the levels of these pollutants in the samples and the quality of oocytes, as well as the success rates of IVF and pregnancy outcomes. The research seeks to understand how oxidative stress and endocrine disruptors may influence reproductive health.

Who should consider this trial

Good fit: Ideal candidates for this study are women aged 18 to 43 who are undergoing their first oocyte retrieval as part of an IVF protocol.

Not a fit: Patients who have previously undergone IVF procedures or are using egg donation will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide insights into how environmental pollutants affect female fertility, potentially leading to improved IVF outcomes.

How similar studies have performed: While studies have explored the effects of environmental pollutants on fertility, this specific approach focusing on IVF patients and oxidative stress is relatively novel.
