within the uterus.
intrauterine device (IUD) (intrauterine contraceptive device) a mechanical device inserted into the uterine cavity for the purpose of contraception. These devices are made of metal, plastic, or other substances and are manufactured in various sizes and shapes. Their effectiveness is based on their alteration of the endometrium and consequent disruption of implantation; there is generally no effect on the menstrual cycle.
After the IUD has been inserted, the patient is instructed to have yearly follow-up examinations. Contraindications to insertion include recent pelvic infection, suspected pregnancy, cervical stenosis, myoma of the uterus, and abnormal uterine bleeding. IUDs are not recommended for women who have never been pregnant because of the severe pain and bleeding that they produce in the majority of these patients.
The IUD is not 100 per cent effective and its use carries some risks. The device does not prevent ovulation or extrauterine implantation; therefore, ectopic pregnancy must be suspected when irregular bleeding or pelvic pain develops in a patient with an IUD. Four to five per cent of all pregnancies occurring in women with IUDs are likely to be outside the uterus. The increased risk for pelvic inflammatory disease is from three to five times that of women who do not use an IUD. Because pelvic inflammatory disease frequently leads to an inability to conceive as a result of scarring and narrowing of the fallopian tubes, the IUD also increases the chances for infertility. Many experts advise against the use of IUDs in women under 25 years of age and in those who hope to have children later in life.
Other possible adverse effects associated with the use of IUDs include uterine perforation, which is rare, and severely increased menstrual flow. Increased dysmenorrhea and intermenstrual bleeding are common in women who have an IUD in place.

Intrauterine contraceptive device (IUD). From Nichols and Zwelling, 1997.
intrauterine
within the uterus.
intrauterine contraceptive device
a mechanical device inserted into the uterine cavity for the purpose of contraception. These devices, used in human gynecology, have been used in draft cattle in Asia for many years. Used occasionally also in dogs. Called also IUD.
intrauterine growth retardation
failure to grow properly in utero in stature, as measured by crown to rump measurement. Pituitary dwarfism in cattle and runting in piglets and puppies are typical examples.
intrauterine medication
medication applied to the uterus via a cervical catheter, or manually in the recently birthed mare, sow or cow.
intrauterine therapy
is a common practice in food animals. Infusion of fluid material or manual placement of solid materials are the usual methods employed. The method has the advantage of achieving maximum concentration of the medicament at the endometrium but only low concentrations are achieved in the deeper layers. See also infusion.
