OBJECTIVE

To evaluate whether pretreatment dehydroepiandrosterone (DHEA) supplementation improves ovarian response markers, ovarian response to standard low-dose gonadotropin stimulation, and in vitro fertilization (IVF) outcomes in poor responders.

DESIGN

Randomized, double-blind, placebo-controlled pilot study.

SETTING

Tertiary reproductive medicine unit.

PATIENT(S): Thirty-two women with anticipated poor ovarian response.

INTERVENTION(S): Randomization into DHEA group (n=16) receiving GNC (25 mg three times a day) or placebo (n=16) starting from at least 12 weeks before the scheduled IVF treatment according to a computer-generated randomization list.

MAIN OUTCOME MEASURE(S): Measurement of monthly ovarian response markers, including antral follicle count (AFC), serum antimüllerian hormone (AMH), and follicle-stimulating hormone (FSH) levels; comparison of ovarian response to a standard dose of gonadotropin stimulation at week 8 and IVF outcomes; and AFC after 12 weeks (primary outcome).

RESULT(S): The DHEA supplementation resulted in statistically significantly higher serum DHEA-S, free androgen index, and follicular DHEA-S levels. No statistically significant differences in the ovarian response markers (AFC, AMH, or FSH), the ovarian response to standard-dose gonadotropin stimulation, or IVF outcomes were found between the two groups.

CONCLUSION(S): No statistically significant improvement in ovarian response markers, ovarian response to standard dose gonadotropin stimulation, or IVF outcomes was found in poor responders receiving pretreatment DHEA.
