Between hsg and laparoscopy, which one is better for a tube test?

Typically: The hsg is done first.

HSG will image: The inside of the fallopian tube and determine if the tube is open between the uterus and the abdominal cavity. Laparoscopy can see abnormalities on the surface of the ovary or within the abdominal cavity (such as endometriosis) that will not be detected by hsg. Which one first depends on the problem. If fertility concerns, hsg first.

Both accurate: Hsg usually first because less expensive and not invasive like surgery. Laparoscopy is no longer a common "test" for infertility because we have good imaging with ultrasound and x-ray without risk and expense of surgery. Then ivf is so successful that we move to using it faster as it provides better outcome and sooner. Best wishes.
