Let's start with the last question. The abbreviation IUD comes from the term Intrauterine Device. How does the IUD work? There are multiple mechanisms of action - it depends on the type of IUD. The mechanical function of device itself induces an aseptic inflammatory reaction, caused by its presence as a foreign body. This is enhanced by the addition of copper, which causes a number of modifications to the endometrium, the lining of the uterus, preventing implantation of the egg. The copper strand also directly affects the sperm, reducing their vitality and mobility as a result of the metal's toxicity. There is also an IUD that releases hormones and acts as a hormonal contraceptive by preventing ovulation.

Insertion should only be done by a trusted gynecologist during the first days following a menstrual period, but no later than the 14th day, to be sure not to interfere with a pregnancy that has just begun. This typically lasts for 20 to 30 minutes, after which you will be asked to rest lying down for a period of time.

The presence of the IUD does not affect normal variations in the menstrual cycle.

Women who use it say that they can't feel it. As soon as it is removed, your body's previous conditions are restored, and with them the possibility of fertilization.

An IUD can remain in the uterus for 2 to 5 years, depending on the woman and the model used. According to the testimonies of those who have used it, it generally leaves no "sense of presence," not even during sexual intercourse. Some women like it very much, others have had it removed because it was causing irritation and inflammation.
