Increased miscarriage rate is associated with at least four components of metabolic syndrome in women with polycystic ovary syndrome undergoing in vitro fertilization or intracytoplasmic sperm injection embryo transfer cycle

Abstract

AbstractAimThis study aimed to investigate the association between the components of metabolic syndrome (MetS) and reproductive outcomes in women with polycystic ovary syndrome (PCOS) undergoing their first in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI) embryo transfer cycle.MethodsThis is a retrospective study that included 720 women with PCOS from January 2018 to December 2021. Anthropometric, biochemical, and reproductive data of the study subjects were collected from electronic medical record. Women with PCOS met <3, 3, and >3 criteria of MetS were classified in group 1, 2, and 3, respectively.ResultsThe miscarriage rate in women with MetS was significantly higher than that in non‐MetS group (23.2% vs. 14.2%, p = 0.03). There was a significant increasing trend in miscarriage rate from group 1 to group 3 (p for trend <0.05). The miscarriage rate in group 3 was significantly higher than that in group 1 (29.3% vs. 14.2%, p < 0.05). Logistic regression analyses showed that women with at least four components of MetS (group 3) were independently associated with a high risk of miscarriage, with the odds ratios and 95% confidence intervals for group 2 and 3 versus group 1 were 1.38 (0.67–2.82) and 2.46 (1.06–5.74), respectively (p for trend = 0.04).ConclusionsPCOS women accompanied with at least four diagnostic criteria of MetS is independently associated with increased miscarriage rate when undergoing their first IVF or ICSI cycle.
