Some patients are diagnosed with tubal incompetence or incompetence, some with tubal inflammation or adhesions, and some with hydrosalpinx, for tubal incompetence or adhesions, we often give two kinds of advice, laparoscopic surgery or IVF, but hydrosalpinx However, tubal effusion is relatively more complicated and there is often no best answer. Anyone with medical knowledge should know that the fallopian tubes are essential for female conception and are the place where sperm and eggs are united, so problems with the tubes can cause infertility in women. Hydrocele is a pathological change in the fallopian tubes, where fluid accumulates in the lumen, and this fluid affects the chance of conception in several ways: 1) the reflux of fluid into the uterine cavity, which can indirectly lead to fluid accumulation in the uterine cavity and affect embryo implantation; 2) the inflammatory factors in the fluid can have toxic effects on the gametes or embryos; 3) the endometrial tolerance is impaired, which means that embryos will not be easily implanted. Therefore, we have come to the conclusion that hydrocele should be treated promptly. How to treat it? There are three most common methods, hydrosalpinx stripping, hydrosalpinx puncture and aspiration, and proximal tubal ligation + distal window opening. The first two methods are easily accepted by patients, but they tend to have mediocre results, a high recurrence rate, and for patients undergoing IVF, hydrocele often decreases pregnancy rates while increasing the risk of ectopic pregnancy. The last method is probably the most commonly recommended by fertility center doctors, but of course is mainly for patients who choose IVF treatment. From scientific statistics, IVF success rates drop by 20-30% if the tubes are not ligated, while the success rate of patients is not affected after ligation. Some patients find this approach difficult to accept, after all, after tubal ligation, there is no more chance of natural conception and the only way to have children is through IVF as a method. Still, for patients who have decided to undergo IVF, we want to exclude all factors that affect the success rate as much as possible. Of course, there are some patients who are young, have been trying to conceive for a very short period of time, and whose tubal effusion is mild, then they can also choose to observe conservatively and try to conceive mainly naturally, and then take effective treatment measures when they have not conceived for more than 1 year. The purpose of writing this article is to hope that infertility patients will pay attention to the disease of hydrocele in the fallopian tubes, and under the guidance of the doctor to carry out timely and effective treatment, and not to wait blindly.
