"Cerclage is a well-known medical procedure which places stitches around the cervix. These stitches are intended to provide support to the cervix in the hopes of reducing preterm birth in women at risk for early labor. Premature labor occurs in about 12 percent of pregnancies and is caused by many factors including a shortened cervix, which can be determined by transvaginal ultrasound."^^<http://www.w3.org/2001/XMLSchema#string>
