Hyperthyroidism is short for hyperthyroidism, and whether or not it affects fertility should be analyzed based on the patient’s condition and not generalized. Hyperthyroidism can affect several systems of the body to varying degrees. For patients with mild disease, no reproductive symptoms and no other serious diseases, after reasonable treatment, it basically will not affect fertility. For patients with relatively serious conditions, such as erectile dysfunction and other reproductive disorders or severe musculoskeletal disorders such as muscle weakness or paralysis, they may not be able to have a successful sex life, which may affect their fertility to a certain extent. Patients have different degrees of illness and different physical conditions. If there is a need for fertility, they should actively communicate with their doctors. Fertility should be based on the patient’s physical condition and follow the doctor’s instructions.
