Is a blocked, fluid-filled fallopian tube caused by a previous tubal infection. Mild cases may be opened surgically. If both fallopian tubes are completely blocked (hydrosalpinges), conception can not occur without medical intervention. In vitro fertilization (IVF) is the method of choice. The fluid from the hydrosalpinx appears to reduce the success of embryo implantation and increase the chance of miscarriage. Because of this, your physician may recommend removing your tube(s) to increase your chances of success with IVF.
