摘　　要：Objective:To compare the effectiveness of inositol and metformin on the clinical characteristics,and endocrine and metabolic profiles of infertile polycystic ovarian syndrome(PCOS)women from Vietnam.Methods:From June 2018 to August 2022,a randomized trial was undertaken at the Hue Center for Endocrinology and Reproduction on infertile women aged 18 to 40 years with polycystic ovarian syndrome.The clinical,endocrine,and metabolic features of these individuals were assessed before and after 3 months of treatment with 2 g of inositol or 1700 mg of metformin per day.Natural pregnancy rates,adverse effects,and tolerance of inositol were recorded.Results:The study included 171 infertile PCOS women who were eligible to participate and took part in the baseline assessment,of whom 132 women participated in data analysis after 3 months.After metformin treatment,42.1%of women with oligomenorrhea experienced regular menstruation.Metformin significantly lowered body mass index(BMI),waist circumference and testosterone levels,but had no effect on other clinical characteristics,endocrine profiles,or metabolic profiles.29.2%Of women reported experiencing side effects.21%Of them attained pregnancy,which resulted in 17.1%of live births.In the inositol group,the rate of regular cycle increased by 18.2%and the total testosterone concentration significantly decreased.In overweight/obese women with PCOS,inositol significantly decreased weight,BMI,waist and hip circumferences(P<0.05).100%Of women tolerated inositol and continued treatment.18.9%Of them became pregnant,leading to 17%of live births.Conclusions:Metformin and inositol can improve weight and waist circumference in overweight/obese infertile women with PCOS.Metformin is associated with a higher rate of regular menstruation,whereas inositol is associated with a lower rate of adverse effects.The spontaneous conception,clinical pregnancy,and live birth rates between two groups are comparable.
