What is an HSG?

HSG (Hysterosalpingography) is an X-ray test that checks whether your fallopian tubes are open and examines the shape of your uterine cavity. It is commonly used as part of a fertility evaluation.

Why is an HSG done?

  • To check whether the fallopian tubes are open or blocked
  • To examine the shape and structure of the uterus
  • As part of investigating difficulty in conceiving

How to prepare for an HSG

  • The test is scheduled on specific days of your menstrual cycle — usually days 6 to 12, after your period ends and before ovulation
  • Your doctor may suggest taking a pain reliever beforehand
  • Tell Dr. Chandak if there is any chance you could be pregnant, or if you have an active pelvic infection — the test should be avoided in these cases

What happens during the procedure

A thin catheter is placed through the cervix, and a contrast dye is gently injected into the uterus. X-ray images are taken as the dye moves through the uterus and fallopian tubes, showing whether it flows through freely. Mild period-like cramping during the dye injection is common.

What happens after the procedure

Light spotting and mild cramping for a day or two afterward is normal. Contact the clinic if you experience fever, heavy bleeding, or severe pain.

Is an HSG safe?

Yes, it is generally safe. Uncommon risks include infection or an allergic reaction to the contrast dye — Dr. Chandak will discuss this with you beforehand.
