We generally do not recommend hysterosalpingography for patients with hyperthyroidism. Reasons: 1. Because there is iodine in the contrast agent . Iodine agent intake can affect thyroid function, or can cause disease exacerbation, or hyperthyroidism emergency occurs. 2, Hyperthyroidism is most importantly related to the levels of hormones in the menstrual cycle, reproductive system and reproduction. Hyperthyroidism may affect pregnancy. We are less likely to recommend pregnancy during the period when hyperthyroidism is not effectively controlled. For patients with hyperthyroidism before the thyroid function has not returned to normal, suspected of tubal problems, and forced by the urgency of time, there is a requirement for treatment of the disease, to rule out tubal problems, but also can only do a simple tubal fluid, a simple judgment of the tubal situation, but he can not replace the tubal imaging. After the thyroid function is normalized, it is still necessary to do hysterosalpingography to understand the uterine cavity and fallopian tube situation in full detail.
