Abstract

Introduction: Polycystic Ovary Syndrome (PCOS), the most common endocrinological problem among women in the reproductive age, is characterized by chronic ovulatory dysfunction, hyperandrogenism, and raised Luteinizing hormone : Follicle Stimulating Hormone (LH:FSH) ratio. Obesity and insulin resistance have been linked to PCOS. However, there is recently a growing population of thin, lean women who are diagnosed with PCOS.

Aim: This study aimed to compare normal and high Body mass index (BMI) women with PCOS and to investigate the correlation between BMI and LH/FSH ratio.

Methods: It was a case -control study at the Department of Obstetrics and Gynaecology, Qassim University clinic, Saudi Arabia. Women with PCOS were included in the study and were classified according to their BMI. Their computerized records were retrieved for the demographic, clinical, and laboratory data. The study groups were compared by the t-test and the Spearman correlation between BMI and LH/FSH ratio was calculated.

Results: A total of 63 women were included in this study (normal BMI group: n=30, and high BMI group: n=33). There was no difference between the two groups in terms of the LH/FSH ratio (2.76 vs. 2.79, P=0.48). There was no significant correlation between BMI and LH/FSH ratio, prolactin, or Thyroid stimulating hormone (TSH ) levels (Spearman correlation with >0.05).

Conclusion: The data suggests that the body mass index was not correlated with increased LH/FSH ratio. Since LH/FSH ratio was the same in normal BMI women, healthcare professionals need to think about ways to normalize this ratio beyond weight reduction.
