DHEA is involved in the regulation of follicular growth in the ovaries. In a 2000 report, five IVF patients who had low ovarian response were treated with oral DHEA (Casson et al, Hum Reprod 2000;15:2129). A small increase in the ovarian response to hormonal stimulation was noticed. Barad and Gleicher reported their relatively extensive experience, summarizing treatment outcome in 25 IVF low-responders treated with oral DHEA pills (Barad and Gleicher, Hum Reprod 2006; 21, 2845). They observed increased increases in fertilized oocytes, normal day 3 embryos, and number of embryos transferred after DHEA treatment compared with a previous treatment outcome before DHEA.
