There is still no clear consensus on the poor responder (PR) definition, however, the European Society of Human Reproduction and Embryology (ESHRE) suggested, in 2011, the Bologna criteria, which includes, for a poor ovarian response definition, at least two of the following three characteristics: age > 40 years, the number of oocytes previously recovered equal to or less than three, and low ovarian reserve tests score. It is noticed that, despite the use of different effective ovulation stimulation protocols, clinical pregnancy rates remain low in PR. In recent years, however, many authors, including Casson et al., reported the beneficial of DHEA supplementation on ovarian response in this group. Dehydroepiandrosterone (DHEA), a precursor of estradiol (E2) and testosterone (T), originates from the reticularis adrenal zone and from ovarian theca cell. In this chapter, we intend to demonstrate the potential benefits of DHEA supplementation in women with poor response in IVF outcomes.
