Which test is used to assess the patency of the fallopian tubes in females?

The test used to assess the patency of the fallopian tubes in females is the hysterosalpingogram (HSG). This procedure involves the use of a special dye that is injected into the uterine cavity and fallopian tubes, followed by X-ray imaging. By visualizing the flow of the dye through the tubes, healthcare providers can determine if the fallopian tubes are open (patent) or blocked, which is crucial for evaluating female infertility.

This method is particularly important for diagnosing conditions that might affect fertility, such as tubal occlusion due to scarring, infection, or endometriosis. The ability to visualize the passage of the dye helps in identifying any abnormal conditions present in the reproductive system, making HSG a standard procedure in fertility assessments.

While other tests, like an endometrial biopsy, focus on examining the inner lining of the uterus for abnormalities, and laparoscopy provides a direct view of the pelvic organs but does not primarily assess tubal patency, the hysterosalpingogram is specifically designed for this purpose.
