Hysterosalpingography (HSG) is typically performed a few days after the menstrual period ends.

Hysterosalpingography (HSG) is an imaging examination used to evaluate the patency of a woman's fallopian tubes. Generally, it is most appropriate to perform HSG 3 to 7 days after the end of menstruation. During this period, vaginal secretions are minimal, and the vagina is relatively clean, which facilitates smooth implementation of the procedure and reduces the risk of infection afterward. Additionally, sexual intercourse should be avoided for three days before the HSG. After the procedure, personal hygiene should be maintained, and rest and recovery should follow the doctor's recommendations. Hysterosalpingography is an invasive procedure that may have certain effects on a woman's body. Therefore, it should be performed under a physician's guidance, and precautions before and after the procedure must be strictly followed. Moreover, specific requirements may vary among hospitals and physicians, so it is advisable to consult with a doctor and understand relevant details before undergoing the examination.
