henotypes of polycystic ovary syndrome (PCOS) include four groups depending on the presence of the following features: ovulation disorder (OD), hyperandrogenism (HA), and polycystic ovary morphology (PCO). Four groups of phenotypes of PCOS are: A (OD+HA+PCO), B (HA+OD), C (HA+PCO), D (OD+PCO). In vitro maturation (IVM) is a safe and effective method for infertility treatment in PCOS patients. There is no study that investigates the impact of phenotypes on IVM outcomes. Objective: To investigate the impact of PCOS phenotypes on IVM outcomes. Method:This was a secondary analysis of a randomized controlled trial conducted on PCOS patients who underwent IVM at IVFMD, My Duc Hospital, Ho Chi Minh City. Outcomes of IVM treatment were compared among four PCOS phenotypes. Result: F-rom 01/2018 to 04/2019, a total of 198 patients were recruited into this study, of which 37 patients with phenotype A (18.9%) while 159 with phenotype D (81.1.%), no patient with phenotype B or C. The number of oocytes retrieved was significantly higher in group A as compared to group D (20.00±11.86 versus 12.78±7.15, p <0.001), meanwhile the oocyte maturation rate was not different. Live birth rate was not different between phenotype A and D (29.7% versus 37.1%, p=0.514). Conclusion: The common phenotypes of Vietnamese PCOS women are A and D. Preliminary results show that there is no impact of PCOS phenotypes on outcomes of IVM treatment.
