Obese and Non-obese Polycystic Ovarian Syndrome: Comparison of Clinical, Metabolic, Hormonal Parameters, and their Differential Response to Clomiphene.
Objective
To study the clinical, metabolic, hormonal parameters, and differential response to clomiphene among the obese and non-obese PCOS (polycystic ovarian syndrome).


Design
Prospective observational study.


Setting
Infertility OPD, a government hospital.


Sample Size
About 164 women with PCOS-related infertility.


Study Groups
Obese PCOS group [body mass index (BMI) ≥23 kg/m2) and non-obese PCOS group (BMI <23 kg/m2).


Results
Of the total 164 PCOS women, 124 (75.61%) were in the obese group with BMI ≥23 kg/m2 and 40 (24.39%) were in the non-obese PCOS group. The prevalence of menstrual irregularity, hypertension, insulin resistance (IR), metabolic syndrome, endometrial hyperplasia, and clomiphene resistance in the PCOS women were 82.34%, 3.66%, 59.76%, 24.39%, 7.93%, and 53.7%, respectively. The Ferriman-Gallwey score, menstrual irregularity, IR [fasting insulin and Homeostatic Model Assessment of Insulin Resistance (HOMA-IR)], metabolic syndrome, deranged lipid profile, and clomiphene resistance were statistically more common in the obese PCOS group (P < 0.05). Hypertension, deranged blood sugar profile, testosterone, androstenedione levels, and endometrial hyperplasia were more common in obese PCOS group but the results were not statistically significant. No significant differences were found in the luteinizing hormone (LH), follicle-stimulating hormone (FSH), LH-FSH ratio, and 17-hydroxyprogesterone (17-OHP) levels between the two groups.


Conclusion
Obese PCOS have a higher risk of adverse outcomes like hypertension, IR, metabolic syndrome, and endometrial hyperplasia. So, targeting obesity in PCOS women will not only help to prevent adverse outcomes but also improve responsiveness to clomiphene citrate.
