Uterous

The uterus has three major functions: to prepare a bed for a fertilized ovum, to nourish the developing embryo during pregnancy, and to expel the fetus. Shaped like an upside-down pear, and tilted forwards, it lies within the pelvis and is held in place, along with its two extensions, the Fallopian tubes, by ligaments and folds of the peritoneum. The cervix forms the lower third, connected by a narrow isthmus to the main muscular body of the uterus. The non-pregnant uterus weighs 45–60 g and is 7–8 cm long but its weight increases more than ten-fold by the end of pregnancy.

IUCD

An Interuterine Contraceptive Device is a device inserted into to the uterine cavity and left for varying periods of time for the purpose of contraception. Throughout the years IUD's made of a range of materials and a variety of sizes and shapes have been designed and manufactured. All modern IUD's are made of polyethylene plastic and are coated in barium, making it possible for them to be seen on X-Ray. Most IUD's have a nylon "tail" which protrudes from the cervix into the vagina to allow you to make check your IUD is still in place.
