Introduction The primary objective of the study was to compare the serum luteinizing hormone (LH) levels in patients with hyperandrogenism on metformin and combined oral contraceptive pills. Secondarily, the study also assessed the serum testosterone, body mass index (BMI), and the time to achieve regular menstruation were also assessed. Methods A quasi-experimental study was conducted at the Department of Medicine, Liaquat University of MedicalHealth Sciences (LUMHS) between June 1, 2019 and May 30, 2020. A total of 200 women fulfilling the clinical and biochemical criteria for the polycystic ovarian syndrome (PCOS) were enrolled, 100 in each group. Considering the inclusion criteria, the patients were picked up from the gynecology outpatient department. After taking a detailed history and physical, abdominal, and pelvic examination, pelvic ultrasonography along with biochemical evaluations of serum LH and testosterone were done in selected patients. Metformin was started at an oral dose of 500 mg daily and maintained at 1500 mg for six months in group A, and oral contraceptive pills were given for a period of six months in group B. Besides body weight and hirsutism, serum LH levels, serum prolactin levels, and serum testosterone levels were performed at the start of the treatment and then repeated after three months and after six months. After six months of menstrual cyclicity, changes in serum LH levels and body weights were assessed in the two groups and the rate of conception in the Metformin group. Results A total of 200 women were enrolled and equally divided into metformin and oral contraceptive groups. Follow-up revealed that a significantly higher number of patients achieved regular menstruation in the metformin group as compared to the oral contraceptive groups (p = 0.03). In the metformin group, 72 patients achieved regular menses, while in the oral contraceptive groups, about 58 patients achieved regular menstruation. Both metformin and oral contraceptive therapy were effective in improving patient outcomes in terms of serum LH, testosterone levels, and BMI. However, metformin had considerably higher rates of improvement as compared to oral contraceptive group patients. The mean serum LH level decreased from 38 mIU/ml to 17.6 mIU/ml in the metformin group (p0.0001), while the mean serum LH level reduced from 37.5 mIU/ml to 27.7 mIU/ml in the oral contraceptive group (p0.01). The change in serum testosterone level after six months was 2.98 ± 0.75 in the metformin group (p0.001) and 1.50 ± 0.64 in the oral contraceptive group (p0.01). Conclusion We revealed that both metformin and oral contraceptives are effective in improving symptomatology in PCOS patients. However, a significantly higher number of patients achieved normal menses with metformin than with oral contraceptives. Moreover, metformin had considerably higher rates of improvements in serum LH levels and serum testosterone levels as compared to oral contraceptive group patients. |
