Outcome of metformin treatment in polycystic ovary syndrome

The polycystic ovary syndrome (PCOS) is a clinical diagnosis. During one year period, 50 women suffering from PCOS were treated with either 850 mg/twice daily or 500 mg/thrice daily along with clomiphene citrate and/or letrozole, with advice for exercise and dietary therapy. Diagnosis of the PCOS patients was made by the presence of two out of the following three criteria: (a) oligo and/or anovulation, (b) hyperandrogenism (clinical and/or biochemical), and (c) polycystic ovaries, with the exclusion of other aetiologies. The mean±SD age of our patients was 26.74±3.85 years, BMI 26.64±2.64 kg/m2, pulse 80.56±4.61 b/min, systolic blood pressure 113.80±4.40 mmHg and diastolic blood pressure 76.10±4.77 mmHg, duration of marriage 6.19±3.20 years, and parity was 43(86%) nulliparous and 7(14%) primiparous. Oligomenorrhoea was present in 100%, hypomenorrhoea in 38%, secondary amenorrhoea in 28% and acne in 70% women. Results showed that 92% women followed advice on exercise and dietary therapy, in maximum number of women progesterone level was 31.40 nmol/L (66%), weight loss was 2 kg (44%), menstrual cycle regular (90%) and pregnancy test negative (90%). Only in 5 cases (10%) pregnancy test was positive.
