Some patients are told during IVF treatment that the ultrasound indicates signs of hydrosalpinx. What is this? What should I do? The uterus is the palace where the baby first grows and develops, just like a house. The fallopian tubes are the long, thin tubes that connect the uterus to the ovaries, just like the hallway outside the house. If there is fluid in the fallopian tube, it is like a leak in the hallway. If this fluid flows back into the uterine cavity, it is like dirty water flowing from the hallway into the house, which can affect the growth of the baby that is going to set up camp in the uterus. There are many reports in the international literature that find that hydrocele reduces the chances of embryo implantation. Therefore, the discovery of hydrocele should be treated. The effective treatment for hydrosalpinx is tubal resection or proximal tubal ligation, which completely removes the fluid producing tissue or intercepts the fluid outside the uterus to provide a clean and comfortable uterine environment for the baby to implant. If we simply aspirate the fluid in the fallopian tube, it is like a leak in the building and just mopping up the floor, the source of the problem is not solved and the fluid will be produced and return to the uterus. Conservative treatments such as anti-inflammatory treatments can also be considered, but most of the hydrocele is caused by chronic inflammation and conservative treatments have little effect.
