Rigorous attention to the design of protocols
tailored to the individual patient, a dedicated staff,
and a laboratory of impeccable quality has translated
into successful outcomes for large numbers of our patients.

Understanding statistics
A comparison of success rates between clinics may not be meaningful because patient medical characteristics and treatment approaches may vary from clinic to clinic.
Many factors affect success rates, and there is no substitute for discussing those face to face with your doctor. However, a few general statements can be made here:
- The age of the female patient is probably the single most important prognostic factor (even though a severe male factor will further decrease the odds of success).
- Cycle cancellation of patients with a limited response, prior to oocyte retrieval, will obviously affect success rates per retrieval.
These first two elements can be identified in the current CDC reporting system.
The next few, however, are not:
- Inclusion criteria vary from center to center: not infrequently, we’ll offer an attempt to patients who have been advised by other Centers to move on to adoption or egg donation.
- Success rates are clearly affected by the number of previous unsuccessful attempts. Since 2010, for example, patients under the age of 35 have ongoing pregnancy rates of 53% for a first cycle (at RMIA), as opposed to 31% during subsequent cycles. However, over 15 years of experience with our Fertility Cost Warranty Programs have convinced us that a majority of those patients that don’t succeed on a first attempt, will achieve their goal over time.
