Is the obstetric outcome of poor ovarian responders different from normal responders? An age-matched controlled study. J. Llácer, P. Baviera, I. Calventus, J. Guerrero, J. Ten, R. Bernabeu

Dr. Ll. Aparicio is making this oral presentation today at the ASRM conference in Boston.

The staff at Instituto Bernabeu is particularly concerned with low responder patients. In fact it is the first center to have a multidisciplinary unit dedicated to furthering the diagnosis, treatment and prognosis of these patients, who are coming more frequently to our consultations.

This study attempts to resolve two apprehensions of both doctors and patients. One with regards to egg quality: will my eggs have a lower quality than patients with high response? And the other is in regards to pregnancy outcome: will I have a higher miscarriage rate? Do I have a higher risk of having a child with genetic issues?

The study presented at the ASRM consists of comparing the evolution of pregnancies achieved at IB from IVF treatments in low responders and patients with an average ovarian response. Each pregnancy was compared to one of a woman with the same age.

The results have cleared up any doubts. We did not find any difference in any of the parameters studied. Patients who became pregnant after a diagnosis of “low responder” did not have a higher risk of miscarriage, premature labor, low birth weight or hospital stay for the newborn.

All of this gives us further proof that egg quality in low responder patients has more to do with age than ovarian reserve. This makes us feel more secure as doctors, as well as patients, when confronted with low ovarian response.
