Objective: Reports of hypothyroidism after hysterosalpingography (HSG) using lipiodol are emerging. The present study was designed to investigate the changes in serum iodine concentration (SIC), urinary iodine concentration/creatinine excretion (UI/Cr), and thyroid function before and after HSG using lipiodol.
Methods: The prospective observation study included 22 infertile euthyroid women with no previous history of thyroid disease.
