Indication of metformin in the management of hormonal dysfunction secondary to polycystic ovarian syndrome: prospective comparative study of 63 cases
Abstract
BACKGROUND: Polycystic ovarian syndrome (PCOS) is the most common hormonal dysfunction in women. It's a cause of female infertility by oligoanovulation, clinical and biochemical hyperandrogenism and polycystic ovaries. Weight loss, firstly proposed in overweight or obese patient suffering from PCOS, aims to reduce hyperinsulinism and hyperandrogenism. Recently, Metformin, an insulin sensitizer, has been proposed as an alternative first line treatment for polycystic ovarian syndrome by improving hyperinsulinemia and hyperandrogenism in these women.
AIM: The aim of our study, and through a literature review, is to demonstrate if Metformin should be used as a first-line drug for infertile women with this syndrome or as an adjunction to Clomifene Citrate, the longest established treatment already used in this syndrome.
METHODS: A prospective comparative study including 63 patients with PCOS has been done during 2 years. Women were randomly allocated to clomifene + Metformin (Metformin group, Metformin took during 8 weeks, 850 mg twice a day, plus Clomifene 100 mg per day during five days) or Clomifene only (100 mg per day during five days). All patients underwent a two- month's diet.
RESULTS: The middle age was about 30.63 years and the body mass index (BMI) was about 29.88 kg/ m(2). We noticed a 6.2% weight loss in both groups (a non significant difference in p=0.04). The median of infertility period was about 2.49 years. The ovulation rate in the Metformin group was 53.12%…
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design. Reported size: 63 participants or records.
