Tubal Patency Test
Tubal patency tests are undertaken when the doctors suspect blockages or pelvic adhesions in the fallopian tubes. These tests include procedures like Gas Insufflation, Hysterosalpingography (H.S.G.), Laparoscopy, etc.
It is a radiological procedure in which x-ray films demonstrate the endometrial cavity & spill of dye from the fimbrial end of both tubes. HSG should be done post menstrually because the endometrial thickness during this period of the cycle is less & hence the sensitivity of the procedure increases. HSG has the advantage of being cost-effective. It also pinpoints the site of the tubal block & outlines the endometrial cavity.
A laparoscopy and dye test is an operation using keyhole surgery to determine why one is having difficulty in becoming pregnant. The dye test will show if your fallopian tubes are blocked. The laparoscopy will help determine if you have endometriosis, pelvic infection, adhesions, ovarian cysts, or fibroids. For some women, minor treatments can be performed at the same time.
