Abstract  Background: Polycystic ovary syndrome (PCOS) is a common condition among female of reproductive age. Vitamin D may involve in the pathogenesis of PCOS. Vitamin D deficiency may exacerbate the symptom of PCOS through precipitating insulin resistance, menstrual irregularities, subfertility, hyperandrogenism, and cardiovascular dysfunction. Aim: The aim of the study is to determine whether normalization of vitamin D level in women with PCOS and hyperandrogenism (clinical and/or biochemical) would result in improvement in the parameters of hyperandrogenism. Materials and Methods: One hundred one women with PCOS and vitamin D deficiency were involved in the study, BMI, and Gallwey-Ferriman score were estimated, 25 (OH) vitamin D, total testosterone, sex hormone binding globulin (SHBG), follicular stimulating hormone (FSH), and luteinizing hormone (LH) were measured and pelvic ultrasound was performed. Forty-nine of these women received weight reduction and lifestyle modification advice and metformin only, while the remaining 52 women received vitamin D in addition, after six months all parameters were re-examined. Results: Adding vitamin D did not result in significant reduction in the Ferriman-Gallwey score or in total testosterone level, also normalization of vitamin D had insignificant effect on the level of sex hormone binding globulin and ovarian polycystic morphology, however it was associated with significant reduction in LH level. Conclusion: Despite the fact that correction of vitamin D deficiency is important for general health, however it is of limited beneficial effect on the biochemical and clinical parameters of hyperandrogenism in women with PCOS.
