Our Success Rates

Make an Appointment

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.

There are many factors that 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 clinic success rates may not be meaningful because patient medical characteristics, treatment approaches, and entrance criteria for ART (assisted reproductive technology) may vary from clinic to clinic.

The Society for Assisted Reproductive Technology (SART) has developed a national website for reporting fertility treatment outcomes. View the most recent SART report on DHMC.
