The efficacy of different insulin-sensitizing agents on treatment outcomes in patients with polycystic ovary syndrome who underwent in-vitro fertilization: A retrospective, record-based, comparative study
Abstract
INTRODUCTION
It is not clear which metformin or inositol is more effective on IVF results. The aim of this study was to compare the effects of Metformin and Inositol co-treatments on IVF outcomes in Polycystic ovary syndrome patients.
METHODS
A retrospective examination was made of the demographic characteristics and the follicular-embryonic development results of PCOS patients applied with an antagonist protocol of ovarian hyperstimulation in the first cycle of IVF with co-treatment of Metformin at 2000 mg/day regularly for 3 months (Metformin co-treatment group, n:35) or Inositol at 4000 mg/day myo-inositol for 3 months (Inositol co-treatment group, n:34) and those not using any co-treatment (FSH only group [control group], n:40).
RESULTS
No significant difference was determined between the groups in respect of demographic characteristics. The HOMA-IR scores and hCG day E2 level were significantly higher in the control group than in both co-treatment groups (p = 0.021, p = 0.018, respectively). The M1 oocyte count was significantly lower in the Metformin group than in the Inositol and control groups (p = 0.001). The GV-DJ oocyte count was significantly lower in both co-treatment groups than in the control group (p = 0.042). No statistically significant difference was determined between the groups in respect of other follicular and embryological development parameters, implantation, clinical pregnancy, live births and abortus rates.
CONCLUSION
Insulin-sensitizing agents may…
How strong is the evidence?
Evidence Hub reads this as a case-control, done in people. Its evidence level is 4 of 5 (Low · observational). Observational designs can show an association but not prove cause.
