Tubal ligation , often referred to as "having your tubes tied," is a surgical procedure in which a woman's fallopian tubes are blocked, tied, or cut. Tubal implants are small metal springs that are placed in each fallopian tube in a nonsurgical procedure (no cutting is involved). Over time, scar tissue grows around each implant and permanently blocks the tubes. Either procedure stops eggs from traveling from the ovaries into the fallopian tubes, where the egg is normally fertilized by a sperm.    Read more.....
