A fallopian tube blockage typically prevents successful passage of the egg to the sperm, or the fertilized egg to the uterus. Causes of tubal infertility include Endometriosis, Pelvic Inflammatory Disease (PID) and scar tissue, adhesions and damaged tube ends (fimbria). Treatment options are IVF (in vitro fertilization) or tubal surgery. Tubal disease is diagnosed by sonohysterogram, hysterosalpingogram and laparoscopy. http:// www.blossomivfindia.com
