Tubal Patency Test

Tubal patency tests are undertaken when the doctors suspect that there are blockages or pelvic adhesions in the fallopian tubes. These tests include procedures like Gas Insufflation, Hysterosalpingography (H.S.G.), Laparoscopy, etc.

Hysterosalpingography (H.S.G.)

It is a radiological procedure in which x-ray films are taken to demonstrate the endometrial cavity & spill of dye from the fimbrial end of both tubes. HSG should be done postmenstrually because the endometrial thickness during this period of cycle is less & hence sensitivity of the procedure increases. HSG has the advantage of being cost effective, OPD procedure which is done without anaesthesia. It also pin points the site of tubal block & outlines the endometrial cavity.


A laparoscopy and dye test is an operation using keyhole surgery to help find out why one is having difficulty in becoming pregnant. The dye test will show if your fallopian tubes are blocked. The laparoscopy will help to find out if you have endometriosis, pelvic infection, adhesions, ovarian cysts or fibroids. For some women minor treatments can be performed at the same time.
