"The blockage of the fallopian tubes, through which the egg travels to the uterus and where fertilization takes place, is a cause of infertility. Sometimes, the distal ends of the tubes can be blocked, causing the accumulation of fluid, a condition known as hydrosalpinx. The treatment typically involves opening the tubes through laparoscopy or, in cases of severe tube damage, removing the tubes before undergoing In Vitro Fertilization (IVF) treatment."
