Intrauterine contraception - introduction into the uterus of special devices that prevent conception.
CMV causes changes in the contractile function of the uterus, aseptic inflammation and altered activity of endometrial enzymes, acceleration of peristalsis in the fallopian tubes, and others. The result is a violation of the migration of spermatozoa, acceleration of entry into the uterus and death of a fertilized egg, abortion.
The conditions that determine the choice of IUD as a method of contraception are the age of a woman over 30, pregnancy and childbirth in the past, a regular menstrual cycle. Contraindications to the use of IUD are divided into absolute - pregnancy, acute and subacute inflammatory processes - and relative - anomalies of the development of the uterus, hyperplastic processes in the genitals, meno- and metrorrhagia, chronic inflammatory diseases of the female genital area, anemia and blood diseases, severe extragenital diseases of inflammatory etiology.
Introduction and removal of IUD can be carried out in outpatient aseptic conditions. Introduce IUD on the 4th-8th day of the menstrual cycle after abortion. After childbirth - preferably in 2-3 months.
Removing the IUD is necessary in 3-4 years, usually it is performed by sipping for a control thread. When the thread breaks, the removal of the IUD is performed instrumentally in the hospital after the expansion of the cervical canal by Gegar dilators No. 4-5.
Complications of IUDs may include pain and expulsion of IUD, especially in nulliparous women.
Often increases blood loss during menstruation and associated iron deficiency anemia.
Acute inflammatory processes or exacerbations of chronic diseases are observed, according to a number of authors, in 1.5-10% of cases among nulliparous women with IUD. Perforation of the uterus - a complication with the introduction of IUD - was noted in 0.04-1.2% of cases. In many respects its frequency depends on the form of IUD, the technique of introduction, the anatomical features of the position of the uterus.
