Our Laboratory Team

Over the past decade, the overwhelming majority of advances and innovations in assisted reproductive medicine have occurred at the level of the fertility laboratory. We are fortunate to have extraordinary scientists responsible for the stewardship of all our andrology and embryology services. Our laboratory team applies a precise and consistent approach to each case to ensure both safety and superior success rates.
