Sexual dysfunction in patients with polycystic ovary syndrome: clinical and hormonal correlations.

Objective: The aim of this study was to investigate the sexual function of patients with polycystic ovary syndrome (PCOS), including the clinical and hormonal characteristics potentially related to sexual dysfunction, in an endocrinology and gynecology ambulatory.

Methodology: Women in ambulatory accompaniment for PCOS (N = 88) were sequentially evaluated by means of the Arizona Sexual Experience Scale (ASEX) and the application of structured diagnostic interview Mini International Neuropsychiatric Interview (version 4.4) for the identification of mood disorders.

Prevalence of psychiatric disorders in patients with polycystic ovary syndrome.

Objective: To investigate the prevalence of psychiatric disorders among women in ambulatory treatment for polycystic ovary syndrome (PCOS) and to correlate its clinical and demographic aspects with mental disorders.

Methodology: Seventy-two patients in ambulatory treatment at the Endocrinal and Gynaecological Institute of the Federal University of Rio de Janeiro were evaluated using Diagnostic and Statistical Manual for Mental Disorders, Fourth Edition criteria by means of MINI (Mini International Neuropsychiatric Interview, version 4.4).

Comparison of two doses of metformin (2.5 and 1.5 g/day) for the treatment of polycystic ovary syndrome and their effect on body mass index and waist circumference.

Fifty-six women with body mass index (BMI) greater than 27 were randomly divided into two groups receiving different doses of metformin (2.5 g and 1.5 g/day) for the treatment of polycystic ovary syndrome to assess its effects on BMI and waist circumference.
