Investigating environmental factors in male congenital testicular conditions

Role of the Environment and Endocrine Disruptors in Child Cryptorchidism

Observational University Hospital, Montpellier · NCT04342026

This study is trying to see if certain environmental factors, like chemicals, are linked to the occurrence of undescended testicles in baby boys.

What this trial studies

This observational study aims to explore the potential association between environmental exposures, particularly endocrine disruptors, and the occurrence of cryptorchidism in male newborns. Cryptorchidism is a common congenital defect that can lead to serious health issues, including fertility disorders and cancer. The study will involve measuring the exposure of parents of male children with and without cryptorchidism to various environmental factors. By identifying potential environmental contributors, the research seeks to enhance understanding of this condition and inform public health strategies.

Who should consider this trial

Good fit: Ideal candidates for this study are parents of male children aged from the neonatal period to 18 years who have been diagnosed with cryptorchidism.

Not a fit: Patients who may not benefit from this study include those whose children do not have endocrine diseases or associated genital or urinary defects.

Why it matters

Potential benefit: If successful, this study could lead to improved prevention strategies for cryptorchidism and related health issues in male children.

How similar studies have performed: Other studies have suggested potential links between environmental factors and cryptorchidism, but this specific approach focusing on endocrine disruptors is relatively novel.
