Introduction: Polycystic ovary syndrome (PCOS) is one of the most important endocrinal diseases in reproductive age group, clinically manifested by hyperandrogenism and anovulation and different other metabolic disturbances that may have important implications for long-term health. Aim and Objective: The aim of this study was to determine the incidence of abnormal luteinizing hormone/follicle-stimulating hormone (LH/FSH) ratio in women with polycystic ovary and to assess the influence of prolactin and thyroid-stimulating hormone (TSH) in the elevated LH/FSH ratio. Study Design: Retrospective observational study. Materials and Methods: Eighty-five women in reproductive age diagnosed with PCOS between June 2012 to June 2014 at the Department of Obstetrics and Gynecology in a tertiary care hospital were selected for the study. Serum LH and FSH levels were determined and LH/FHS ratio (normal range ≤2) calculated in the study subjects. They underwent a detailed clinical, hormonal, and metabolic evaluation, which was performed between the second and third days of a natural or induced menstrual period. Results: Elevated LH/FSH ratio was found in 60 women (70.58%). Normal gonadotropin ratio was detected in 25 women (29.41%). Statistically significant differences in serum TSH levels were noted between groups with normal and elevated LH/FSH ratio. However, no statistically significant difference was noted in other endocrine parameters. Further analysis revealed a slight negative correlation of TSH with prolactin in the study subjects of PCOS with an 'r' value of − 0.3. Conclusions: LH/FSH ratio is one of the characteristic attribute of PCOS women. In the present study, this abnormality was detected in 70% of patients. Hypothyroidism was a common endocrinal abnormality and prolactin was inversely correlated to TSH levels in PCOS patients.
