About

Aim of study: To investigate whether four months of metformin treatment before IVF (in-vitro-fertilisation) or ICSI (intra-cytoplasmic-sperm-injection) might increase clinical pregnancy rate in normal-weight (body mass index [BMI] below 28 kg/m3) in PCOS (polycystic ovarian syndrome) women.

Full description

PCOS is an hormonal disease including hyperandrogenism, oligo-or anovulation and/or polycystic ovaries by ultrasound. PCOS women often suffer insulin resistance or even diabetes risk as well as a full blown metabolic disease.

These women often suffer infertility due to their lack of regular ovulations. Metformin is a well known anti-diabetic drug, and in some PCOS women metformin might decrease the hyperandrogenism, improve insulin resistance and give more regular ovulations. Thereby increase chance of pregnancy. Our hypothesis is that metformin will increase clinical pregnancy rates both spontaneously and following IVF/ICSI.
