Is there an association between endometriosis and thyroid autoimmunity?

Objective: It has been suggested that non-uterine endometrial implants can express thyroid-stimulating hormone receptors, thus inducing the formation of thyroid-stimulating immunoglobulin. We aimed to compare the autoantibody positivity in patients with and without endometriosis and to determine whether there is a difference in the incidence of thyroid diseases.

Methods: This prospective observational study was conducted on 102 women who had been operated on for benign gynecological diseases.
