It is important to predict the serum thyroid hormones level in females during infertility to prevent its occurrence later on. In this study, we studied serum thyroid hormones and menstrual irregularities during infertility.

 Method :  A case control study was performed in 90 infertile patients with menstrual irregularities and 50 healthy matched women. Three biochemical parameters were measured in serum, hormones triiodothyronine (T3), tetraiodothyronine (T4) and serum thyroid stimulating hormone (TSH) by TOSOHAIA–360, immunoassay method.

 Result : Serum T3, T4 and TSH level were statistically highly significant in infertile women. Serum thyroid stimulating hormone level was found at higher side in infertile women.

 Conclusion :  High incidence of hypothyroidism was found in infertile women and it shows a positive correlation with menstrual disorder.
