Evaluation of fenugreek [Trigonella foenum-graceum L.], effects seeds extract on insulin resistance in women with polycystic ovarian syndrome

ABSTRACT

PCOS [Polycystic Ovarian Syndrome] is associated with insulin resistance, obesity and disorders of lipid metabolism as well as infertility. Fenugreek seeds extract is successfully used in lowering blood glucose. Metformin has also the same effect but in a different way. The aim of this study was the assessment of fenugreek effects on insulin resistance in women with PCOS. This was a prospective randomized, double-blind, placebo-controlled trial. The study was conducted at the Montaserieh Hospital in Mashhad University of Medical Sciences, Mashhad, Khorasan Razavi Province, Iran. The patient population included 58 oligo-anovulatory PCOS women with typical ovaries. Women were randomly allocated to receive hydroalcoholic extract of fenugreek seeds in capsules with metformin [n = 30] or placebo capsules with metformin [n = 28] and were assessed before and every 4 weeks within a treatment period of 8 weeks. Menstrual disturbance and metabolic parameters [markers of insulin resistance and hormonal parameters] were measured. Insulin resistance based on HOMA-IR [homeostasis model assessment for insulin resistance] model was not significantly different between two groups. Ultrasound scans were performed before and at the end of 8 weeks treatment with significant decrease in PAO [polycystic appearing ovaries] in group 1 [p = 0/01]. Adjuvant therapy to the fenugreek seeds extract [with metformin] in PCOS women improved the sonographic results and menstrual cyclicity
