For many women facing obstacles on their fertility journey and considering In Vitro Fertilization (IVF) technology, the necessity of undergoing a hysterosalpingography (HSG) examination often becomes a question in their minds. This examination, using X-rays and a contrast agent, can clearly show the anatomical structure of the uterine cavity and fallopian tubes, helping doctors determine if there are any potential problems affecting conception, with a diagnostic accuracy of approximately 85%. So, when planning for USA IVF, do we need to undergo this examination?

 

Hysterosalpingography, like drawing a clear "map" of the uterus and fallopian tubes, has indications including unexplained infertility, frequent miscarriages, a history of ectopic pregnancy, and a history of reproductive system inflammation. It can effectively mark fallopian tube blockage and other damage, uterine structural abnormalities (such as uterine fibroids, polyps), endometriosis, and other lesions. However, it is important to note that pregnancy, allergy to the contrast agent, acute pelvic inflammatory disease, abnormal uterine bleeding, severe heart, liver, and kidney failure, infectious diseases, and hyperthyroidism are listed as contraindications for this examination.

 

The hysterosalpingography examination is usually performed in a hospital with the patient in a supine position, generally without anesthesia. A gynecologist will slowly inject the contrast agent into the woman's body through a thin catheter. There may be slight discomfort during the examination, but it usually disappears within a few minutes. Subsequently, the doctor will observe the flow of the contrast agent in the uterus and fallopian tubes through X-ray imaging, thereby assessing their shape and patency.

 

Through the images obtained from hysterosalpingography, doctors can diagnose various pathological problems of the uterus and fallopian tubes, and evaluate the size, shape, position, and patency of the uterus and fallopian tubes. Under normal circumstances, the X-ray will show the uterine cavity as an isosceles triangle, and the fallopian tubes will appear as uniform band-like shadows. When there is inflammation, fibroids, or polyps, irregular shapes of the endometrium may be observed; if there are adhesions in the fallopian tubes, the image may show alternating dark and light areas.

 

Although the core of USA IVF technology lies in in vitro fertilization, bypassing the function of the fallopian tubes, experts usually still recommend that women consider undergoing fallopian tube examination before IVF. The main purpose of this is to rule out the possibility of hydrosalpinx and inflammation. Dr. Nathan Zhang points out that the harmful substances produced by hydrosalpinx and inflammation may have adverse effects on the transferred embryos and reduce their potential for implantation and development.
