At ESHRE 2026, researchers presented work exploring endocrine-disrupting substances in the oocyte environment and their possible relationship with assisted-reproduction parameters.

The research aims to understand exposures that are difficult to measure in everyday life and that may interact with hormonal or cellular processes. The studies are heterogeneous and do not allow specific clinical effects to be attributed to a single substance.

A growing research field

Evidence on environmental exposures and fertility continues to evolve. These studies help define questions for prospective research using more precise exposure measurements.
