Hysterosalpingografie

Hysterosalpingography, often abbreviated as HSG, is a radiological procedure used to examine the internal contour of the uterus and the fallopian tubes. It is a diagnostic tool primarily employed in the evaluation of female infertility and recurrent miscarriages. The procedure involves the introduction of a contrast dye through the cervix into the uterine cavity and then into the fallopian tubes. As the contrast medium fills these structures, X-ray images are taken. This allows radiologists to visualize the shape of the uterus, identify any abnormalities within it, such as polyps or fibroids, and assess whether the fallopian tubes are open or blocked. Blockages in the fallopian tubes can prevent fertilization by hindering the passage of sperm to the egg or the transport of a fertilized egg to the uterus. HSG is typically performed in the follicular phase of the menstrual cycle, usually between day 6 and day 12, to avoid interfering with a potential early pregnancy and to minimize discomfort. While generally safe, potential risks include infection, allergic reaction to the contrast dye, and uterine cramping. The procedure itself is relatively quick, usually lasting around 30 minutes. The interpretation of the X-ray images by a radiologist is crucial for determining the next steps in fertility treatment or further investigation.
