The Effect of Metformin on Serum Insulin, Androgens and AMH in PCOS Patients
Abstract
Forty eight PCOS patients were included . The diagnosis of PCOS was made based on the three criteria set by the Rotterdam Consensus meeting definition of PCOS (ESHRE, ASRM, 2004). The criteria were as follows:
1. history of chronic anovulation defined as cycle length \> 35 days, or less than 9 cycles per year or amenorrhoea (cycle length \> 12wks),
2. infertility with hirsutism or acne or elevation of one or more of serum androgen levels
3. ultrasonographic findings of polycystic ovaries ( increased ovarian volume, more than eight follicles in an ovary ranging from 2-10mm).
the studied subjects were to receive metformin 850 mg twice daily over a period of 6 months. Blood samples were collected at the start of the study, before receiving metformin, where baseline serum insulin (fasting and 2 hr postprandial), sex hormone binding globulin (SHBG) , total and free testosterone, Dihydroepiandrostenedione sulphate (DHEAS) and Antimullerian Hormone (AMH) were obtained before starting metformin. Blood samples were collected at 3 and 6 months respectively of metformin treatment , to asses its effect on serum levels of the previously mentioned hormonal parameters.
Conditions: Polycystic Ovarian Syndrome.
Primary outcome: hormonal changes.
Enrollment: 48 participants.
How strong is the evidence?
Evidence Hub reads this as a clinical trial, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence. Reported size: 48 participants or records.
