Illustration of fallopian tube infertility. A fallopian tube extends from the uterus to each ovary; it transports eggs and sperm, and is the site of fertilization. Disorders of the fallopian tubes are thus a common cause of infertility. Here a blockage of the tube (lower left) has occurred. The ovary is at lower centre (grey). The funnel- shaped opening of the fallopian tube with its finger-like projections (fimbriae) are at upper centre. An infection is causing the fallopian tube opening to weep fluid. Blockage of the tube lead- ing to infertility can be through bacterial infec- tion causing tube inflammation (Salpingitis); venereal disease; and ectopic pregnancy.
