How soon can you get pregnant after a hysterosalpingography?

Generally, it is safe to conceive 1 to 2 months after a hysterosalpingography (HSG). The detailed explanation is as follows:

Hysterosalpingography involves radiation exposure and typically uses X-rays to image the pelvic area. A contrast agent is injected through a catheter into the uterine cavity and fallopian tubes, allowing visualization of the uterine cavity and tubal anatomy, including any blockages. The contrast agent takes approximately 1 to 2 months to be fully metabolized and eliminated from the body. Getting pregnant too soon may increase the risk of embryonic developmental abnormalities; therefore, patients are advised to wait 1 to 2 months before attempting conception. During this period, effective contraception should be used during sexual intercourse to prevent potential adverse effects of residual contrast agent on both the patient and the developing fetus.

In addition, hysterosalpingography is usually scheduled 3 to 7 days after the end of a woman’s menstrual period, which is generally outside the ovulation phase and thus has minimal impact on oocytes. After the procedure, patients should focus on improving their nutrition by consuming more fresh fruits and vegetables, take folic acid as prescribed, avoid smoking and alcohol consumption, ensure adequate sleep, and support healthy oocyte development. If any physical discomfort occurs, prompt medical attention is recommended.
