Description/Abstract

Objective: To investigate whether follicular phase characteristics associated with ovarian aging can be observed in women of normal reproductive age, who had previously shown a poor response to ovarian hyperstimulation for IVF.

Design: Observational, prospective study.

Setting: Tertiary fertility center.

Patient(s): Eleven regularly cycling, ovulatory women, aged 29–40 years who previously presented with fewer than four dominant follicles after ovarian hyperstimulation for IVF.

Intervention(s): Frequent serum hormone assessments and transvaginal ultrasound during the follicular phase of a spontaneous, unstimulated cycle.

Main Outcome Measure(s): Duration of the follicular phase; serum LH, FSH, E2, P, inhibin A, and inhibin B levels; and number of antral follicles observed by ultrasound. Results were compared with the cycle characteristics of a reference population of 38 healthy normo-ovulatory women aged 20–36 years (as published elsewhere).

Result(s): Poor responders had significantly fewer antral follicles than controls. Median FSH concentrations were significantly higher compared with controls, but the majority had FSH levels within the normal range. Follicular phase P levels were significantly higher in poor responders. Duration of the follicular phase, E2, and inhibin A and inhibin B serum levels did not differ between poor responders and controls.

Conclusion(s): Normo-ovulatory regularly cycling women with a previous poor response to ovarian hyperstimulation for IVF show follicular phase characteristics suggestive of ovarian aging.
