Description
Summary:To investigate whether IVF outcome of patients older than 40 years of age with basal FSH levels less than 15 IU/L differs from that in patients 40 years of age or younger with basal FSH levels of 15 IU/L or greater. Prospective observational study. Tertiary academic fertility center. Women 41 years of age or older with basal FSH levels less than 15 IU/L (n = 50), and women 40 years of age or younger with elevated basal FSH levels (n = 36) undergoing their first IVF cycle. IVF treatment using a long suppression protocol with recombinant FSH at a fixed starting dose of 150 IU/L. Ovarian response, ongoing pregnancy rates, and implantation rates. The high FSH group experienced more cycle cancellations due to absent follicular growth than did the high age group (31% vs. 8%). However, the high FSH group had better implantation rates per embryo (34% vs. 11%), higher ongoing rates per ET (40% vs.13%), and higher ongoing pregnancy rates per cycle (25% vs. 10%). In both groups, poor responders had lower pregnancy rates. The outcome of IVF differs between patients older than 40 years of age with normal FSH levels and relatively young patients with elevated FSH levels. This finding may have implications for the management of these patients.
