An HSG (Hysterosalpingography) is a specialized X-ray procedure used to evaluate the uterus and fallopian tubes, primarily in the assessment of female fertility. During this test, a contrast dye is gently introduced through the cervix into the uterine cavity, allowing X-ray images to clearly outline the shape of the uterus and the patency (openness) of the fallopian tubes. The procedure helps detect conditions such as tube blockages, fibroids, polyps, adhesions, or abnormalities in the uterine cavity that may affect conception. HSG is minimally invasive, safe, and typically performed shortly after menstruation to ensure optimal accuracy and comfort. Real-time imaging enables precise visualization and immediate interpretation of results, making it an essential diagnostic tool for women undergoing fertility evaluation or planning pregnancy. The test is usually completed within a short time, with mild discomfort possible, and patients receive guidance on preparation and aftercare.
