Abstract:

Objective: To evaluate the effectiveness of melatonin supplementation during controlled ovarian hyperstimulation for women undergoing assisted reproductive technology.Methods: We searched PubMed, Embase, the Cochrane Library, the CNKI Database, VIP Database, Wanfang Database and the Chinese Biomedicine (CBM) Database for eligible studies published by the end of January 2020. Two independent evaluators screened the randomized controlled trials retrieved the effects of melatonin supplementation during controlled ovarian hyperstimulation in women undergoing assisted reproductive technology. The quality of the included studies was assessed, and the data were extracted for meta-analysis using RevMan 5.3.Results: A total of 6 RCTs involving 767 cycles were included. Among them, 419 cycles were in the melatonin group and 348 cycles in the control group. The meta-analysis showed that the numbers of MⅡ oocytes, high-quality embryos and the E2 levels on hCG day in the melatonin group was significantly higher than those in the control group (P<0.05). The melatonin supplementation during controlled ovarian hyperstimulation moderately elevated the clinical pregnancy rate, but the difference was not significant (WMD=1.34, P=0.08, 95%CI: 0.96-1.86). However, there were no significant differences in the number of oocytes retrieved and embryos transplanted, fertilization rate and abortion rate between the two groups (P>0.05).Conclusions: The currently available evidence suggests that melatonin supplementation during controlled ovarian hyperstimulation for women undergoing assisted reproductive technology can improve the numbers of MⅡ oocytes and high-quality embryos, and clinical pregnancy rate. Larger sample size and multicenter RCTs are needed to verify the above conclusions.
