The main reason for having a hysterosalpingogram is that you want to have a baby and get pregnant, and there are two main aspects of damage to the body, one is the contrast agent, and the other is the effect of uterine operation on the body, mainly these two aspects. First of all, the contrast agent, in the past, iodine oil was used for contrast, surely the side effects on the body are relatively large, and strict contraception should be used because it may have an effect on the fetus, and it is usually required to get pregnant after three months. Later on, the contrast agent was changed to pantethine, which has relatively less effect on the body, and pregnancy can be conceived normally in the second month after the contrast agent is used. Nowadays, there is also ultrasound imaging, the contrast agent also has very little effect on the body, usually after the operation after the imaging can have a normal child in the second month. Secondly, the main damage to the body is the uterine operation, because usually there is a cervical mucus plug at the cervical opening, preventing the cervix and the uterine cavity from communicating with the outside world. Because of the uterine operation, the cervical opening is open, if you don’t pay attention to the prevention after the operation, such as coitus after the end of the imaging or taking a bath, swimming, soaking in hot springs and so on, then it will be easy to cause retrograde infection, pelvic infection, which is the other side of the impact.
