Hysterosalpingography (HSG), commonly known as a 'uterine film', may increase the chances of pregnancy in certain situations. The contrast agent used during the procedure can open minor blockages in the fallopian tubes, ensuring their patency. The removal of small obstructions in the tubes can facilitate the passage of a fertilized egg to the uterus, thereby potentially supporting fertility. However, this effect may not apply to everyone and should not be considered a definitive infertility treatment method.
