The Role of Dehydroepiandrosterone in Improving in vitro Fertilization Outcome in Patients with DOR/POR: A Systematic Review and Meta- Analysis.

BACKGROUND AND

OBJECTIVE

Although many trials have evaluated the use of dehydroepiandrosterone to improve outcomes in poor responders undergoing assisted reproductive technology treatment, evidence supporting this approach is controversial. We aimed to conduct a systematic review and meta-analysis of existing published data to further elucidate and supplement the use of Dehydroepiandrosterone (DHEA) to improve the effectiveness of vitro fertilization in patients with diminished ovarian reserve or adverse ovarian reactions.

METHODS

PubMed, Embase, Cochrane Library, and the Web of Science databases were searched through December 2020. Oocyte yield, metaphase II oocytes, fertilized oocytes, top-quality embryos, clinical pregnancy rate, ongoing pregnancy rate, and live birth rate were analyzed as relative outcomes. Meta-analysis was performed and fitted to both fixed-effects models and random-effects models.

RESULTS

Eight prospective randomized controlled studies, five prospective case-control studies, and three retrospective cohort studies were conducted with a total of 1998 participants. Meta-analyses of these studies showed a significantly higher number of oocytes retrieved (WMD 1.09, 95% CI 0.38 to 1.80), metaphase II oocytes (WMD 0.78, 95% CI 0.16 to 1.40), fertilized oocytes (WMD 0.84, 95% CI 0.42 to 1.26), top-quality embryos (WMD 0.60, 95% CI 0.34 to 0.86), clinical pregnancy rate (RR 1.35, 95% CI 1.13 to 1.61), and ongoing pregnancy rate (RR 1.82, 95% CI 1.34 to 2.46), although there was no difference in live birth rate (RR 1.35, 95% CI 0.94 to 1.94) in the DHEA supplementation groups compared with that in the control groups.

CONCLUSION

Oral DHEA supplementation appears to improve some IVF outcomes. On the basis of this limited evidence, we conclude that further studies are required to provide sufficient data.
