OBJECTIVE: To evaluate the effect of insulin resistance (IR) on in vitro fertilization (IVF)/intracytoplasmic sperm injection (ICSI) outcomes in patients with polycystic ovary syndrome (PCOS).
STUDY DESIGN: PubMed, Google Scholar,Web of Science, Embase, Scopus and the Cochrane Library were searched to identify relevant studies. A total of 6,137 PCOS women undergoing IVF/ICSI with or without IR were included in the systematic review and meta-analysis.
RESULTS: The systematic review and meta-analysis included twelve observational studies that were free from inherent bias. When comparing PCOS women undergoing IVF/ICSI, the IR and non-IR groups did not show significant differences in oocytes retrieved (WMD = -0.63, 95 % CI: -2.37 to 1.12, P = 0. 483), fertilization rate (WMD = 1.01, 95 % CI: -0.66 to 2.67, P = 0.236; OR = 0.97, 95 % CI: 0.79 to 1.19, P = 0.783), and live birth rate (OR = 1.02, 95 % CI: 0.78 to 1.33, P = 0.892). However, the group with IR had a lower number of MII oocytes (WMD = -1.07, 95 % CI: -1.54 to -0.59, P < 0.001), total embryos (WMD = -1.37, 95 % CI: -1. 78 to -0.95, P < 0.001), and clinical pregnancy rate (OR = 0.77, 95 % CI: 0.59 to 0.99, P = 0.042), as well as a higher miscarriage rate (OR = 1.11, 95 % CI: 1.02 to 1.22, P = 0.017) compared to the non-IR group.
CONCLUSION: In women with PCOS, IR had a negative impact on IVF/ICSI outcomes. To obtain more favourable empirical support, larger studies are necessary.
