Our Success Rates

The meticulous work of our embryologists, in combination with the expertise of our medical staff, enables us to consistently achieve high success rates with a low multiple birth rate.

Many factors can contribute to an infertility program's success rates: the treatment approaches of each program; the age of the patient; and the cause of their infertility. Success rates naturally decline as women get older, and drop significantly after age 37.

A comparison of various clinics' success rates may not be meaningful because patients' medical characteristics, treatment approaches, and entrance criteria for ART (assisted reproductive technology) may vary from clinic to clinic.
