Infertility is a big blow to every family. There are many causes of infertility, generally 50% of infertility is caused by women, 30% by men, and 20% by both partners. Therefore, if a couple has not conceived after living together for more than one year without using contraception, they both need to go to the hospital for examination and treatment in time. Conception is a very complicated process. In addition to having normal sperm and eggs and a proper intrauterine environment, it is an extremely important part of the conception process that the sperm and eggs meet and are transported smoothly to the uterine cavity. This task is performed by the fallopian tubes. The fallopian tubes are not only a channel connecting the ovaries and the uterus, but they are also a place for egg storage, sperm delivery and provide sperm-egg union, and have the function of transporting the pregnant egg to the uterine cavity. If there is inflammation in the fallopian tubes, resulting in tubal blockage, sperm will not be able to meet the egg, thus causing tubal infertility. Inflammation of the fallopian tubes may manifest clinically as lower abdominal discomfort and back pain, but a number of patients do not have any conscious symptoms other than infertility. Uterine tubal iodography can help us to diagnose the degree of tubal inflammation and the site of obstruction and determine an effective individualized treatment plan. Tubal inflammation is divided into two types: acute and chronic, depending on the causative factors. Tubal hypertrophy and fluid accumulation in the fallopian tubes caused by chronic tubal inflammation are important causes of female infertility. According to the severity of the disease, it can be divided into hydrosalpinx, tubal adhesion and tubal blockage. If you are diagnosed with tubal infertility, you can choose a suitable treatment plan according to your specific situation: 1. For young patients with a short period of infertility, you can first consider taking Chinese herbal medicine internally and try to conceive while treating. If you cannot conceive after six months to one year of trying, you need to consider more aggressive treatment methods. 2. For patients with proximal tubal obstruction, guidewire intervention can be used, which is a minimally invasive interventional technique for the treatment of tubal blockage infertility with direct and obvious efficacy. The best time to conceive after guidewire intervention is six months. 3. Minimally invasive laparoscopic surgery can be used for infertility patients with good ovarian function and tubal adhesions. The best time to conceive after laparoscopic surgery is six months to one year. If conception is still impossible after one year, in vitro fertilization-embryo transfer is recommended. In vitro fertilization-embryo transfer (IVF-ET, commonly known as in vitro fertilization): For older patients with tubal infertility, especially those over 35 years old, or those with poor ovarian function, or those who still cannot conceive after the aforementioned treatment, in vitro fertilization-embryo transfer is recommended. Currently, the success rate of IVF has reached 40-50%, which is a very effective technique to assist pregnancy. 5. Treatment of hydrosalpinx: Hydrosalpinx indicates inflammatory erosion of the fallopian tubes and adhesions at the umbilical ends of the tubes. These deposited fluids are the remnants of inflammatory exudation and are fluids that are toxic to the embryo. Because the umbilical end of the fallopian tube has been blocked, no eggs can be harvested. Therefore, patients with hydrocele cannot conceive naturally. When IVF is done, if the fluid flows backwards into the uterine cavity it can also affect the implantation of embryos and reduce the success rate of IVF. As a matter of fact, there are three, six and nine different levels of hydrosalpinx, and there are different degrees of hydrosalpinx and different treatment methods. The more accepted practice is that a small amount of hydrocele can be treated by direct IVF-ET or lumpectomy to restore the anatomical structure. For patients with a large amount of hydrocele, surgical treatment followed by IVF-ET is required to improve the conception rate of IVF.
