Moderately elevated levels of basal follicle-stimulating hormone in young patients predict low ovarian response, but should not be used to disqualify patients from attempting in vitro fertilization

Objective: To evaluate and compare IVF outcomes of patients within different age categories who had a normal basal FSH level with outcomes of patients with an elevated day 3 FSH level. Design: Retrospective analysis. Setting: Lame, private IVF center. Patient(s): We analyzed 2,708 patients. Of these, 2,477 bad normal basal FSH levels, and 231 had elevated basal FSH levels (>= 13.03 IU/L). Patients were segregated into various age groups. Intervention: Follow-up. Main Outcome Measure(s): Outcomes of IVF overall, including cancellation rates, oocyte yield, and fertilization, implantation, and clinical pregnancy rates (PRs). Result(s): Cancellation rates were significantly higher in patients with elevated day 3 FSH levels compared with patients with normal FSH levels in all age groups. A significantly lower oocyte yield was observed in patients with elevated basal FSH. Fertilization rates were not affected by FSH levels. A significant decrease in the number of embryos available for transfer in patients 38 with an elevated day 3 FSH level was found. Implantation and clinical PRs were lower in patients >40 years of age who had an elevated day 3 FSH level when compared to same age patients with a normal day 3 FSH level. Loss rates were not significantly different. Conclusion(s): Young women with an elevated basal FSH level should be counseled differently than older women, and should be given adequate counseling and granted the opportunity to undergo an IVF cycle.
