The role of anti-Mullerian hormone and inhibin B in the assessment of metformin therapy in women with polycystic ovarian syndrome.
OBJECTIVE
To evaluate the role of anti-Mullerian hormone (AMH) and inhibin B in the evaluation of the effectiveness of short- (3 months) and long-term (6 months or more) metformin therapy in Iraqi women with polycystic ovarian syndrome (PCOS).


METHODS
This cross-sectional study was carried out at the Biochemistry Department, College of Medicine, University of Baghdad, Baghdad, Iraq from June 2010 to May 2011. It included 38 volunteers of women patients with PCOS, aged 18-38 years, who were classified into: Group I (GI, n=20); Group II included women in GI that were followed up after they were treated with metformin hydrochloride tablet 500 mg 3 times daily for 3 months; and GIII included 18 women that were already on metformin hydrochloride treatment 500 mg tablet 3 times daily for 6 months to 3 years. Investigations included serum measurement of insulin, AMH, inhibin B, androgen hormones using enzyme-linked immunosorbent assay, and mini Vidus techniques.


RESULTS
The mean ± standard error of the mean value of serum AMH levels was significantly decreased in post metformin treatment women (3 months; GII) compared with those before treatment (GI), and those women on prolonged treatment (GIII) (p less than 0.01 for both). However, there was no significant difference in serum AMH between GI and GIII. With respect to serum inhibin B, both women of GI and GII had significant decrease compared with GIII, with no significant changes between GI and GII.


CONCLUSIONS
This study showed the efficacy of serum AMH measurement as a prognostic biochemical marker in the follow up of metformin treatment of PCOS women.
