Study of serum insulin and thyroid hormones levels among infertile females in Bangladesh
Abstract
Background: Infertility has emerged as a global health issue, affecting 8-10% of couples worldwide. Altered insulin and thyroid levels have been identified as potential contributors to infertility. This study aims to examine the status of fasting serum insulin and thyroid hormones in women experiencing primary and secondary infertility, with a focus on evaluating thyroid function and insulin levels among this population.
Methods: The study included 100 women, with 50 experiencing primary infertility (Group A) and 50 with secondary infertility (Group B). Age-matched fertile women served as the control group. All participants were recruited from the infertility unit at Bangabandhu Sheikh Mujib Medical University (BSMMU) in Dhaka. Data were recorded on a standardized data sheet following written consent. Statistical analysis was performed using unpaired Student’s t-tests with SPSS software, version 12.
Result: In this study, the mean fasting serum insulin and TSH levels were significantly higher in infertile women compared to fertile women (p<0.001). Within the infertility group, serum fasting insulin was higher in women with primary infertility than in those with secondary infertility, although this difference was not statistically significant. The mean TSH levels in both infertility groups were significantly elevated compared to the fertile group. Among those with infertility, 28% of women with primary infertility and 24% with secondary infertility had hypothyroidism, while elevated serum insulin levels were observed in 22% and 20% of these groups, respectively. Among the hypothyroid infertile women, 64.2% (9 of 14) with primary infertility and 58.3% (7 of 12) with secondary infertility also had hyperinsulinemia.
Conclusion: This study concludes that fasting serum insulin and TSH levels were higher in infertile women compared to healthy fertile women. These alterations may contribute to menstrual irregularities, ovulatory dysfunction, and infertility. The study also highlights a high prevalence of hypothyroidism with elevated fasting serum insulin levels in infertile women, underscoring the importance of assessing both TSH and insulin levels in the evaluation of infertility.
