This document discusses the potential role of DHEA supplementation in improving oocyte yield and quality in women with diminished ovarian reserve or poor ovarian response. It provides biological plausibility for how DHEA may act on granulosa cells and follicles to reduce apoptosis and recruit more developmentally competent oocytes. The document reviews literature on DHEA's effects and side effects, and discusses using it as an adjuvant treatment in IVF, noting while some studies show benefits to oocyte quantity and quality, robust evidence of improved live birth rates is still lacking. It raises questions that need answering before widespread use and stresses that lack of evidence is not evidence of lack of effect.
