How do IUDS work?

IUD or intrauterine devices are a type of contraceptive control method with a high degree of success in preventing undesirable pregnancy. There are two types on the market, standard IUD are T -shaped devices covered with coated copper, which are inserted directly into the uterus. The insertion process means expansion of the cervix in the doctor's office, so the device can be mounted in the uterus. This may be an uncomfortable procedure, after creating a heavier period, and risk a certain risk of inflammatory pelvic and infection disease. This risk is minimal and most women tolerate IUD very well. These are very popular forms of contraception in European countries and China. The blockade mechanism is approximately the same, but the device also releases a stable flow of progestin, which helps chemically reduce the chances of pregnancy. It tends to reduce the frequency, length and difficulty of the analogue, unlike standard or inert IUD. Has larger factors of side effects and warnings that apply to the use of someOLI type of hormonal contraceptives, as well as IUD of this type.

with the first type of IUD, after inserting into the uterus, the presence of copper around the IUD framework acts as a natural spermimicide. In addition, IUD causes the uterus to produce white blood cells (leukocytes) and prostaglandins in the uterus. Thanks to them, the uterine environment is hostile to sperm and eggs, which significantly reduces potential pregnancy.

During the life of an inert IUD, usually five to ten years, the overall risk of pregnancy is approximately 4%, although for most there is only 1% chance of getting pregnant.

There is a chance that the uterus can exclude IUD, especially in the first year after insertion, and especially in women who have never had children. Animally, when IUDS remains in place, the doctor must remove them and no one should try to remove IUD himself. There are two chains that hang from IUD, which some men feel during contact. If they become issuesThey can be trimmed.

IUD, which release hormones, are plastic and have an inner cylinder that releases hormones at a controlled level. These have been operating for approximately five years, at approximately 99% of efficiency, but can be removed at any time. Methods of hormonal birth control tend to reduce or eliminate ovulation. Progestin increases uterine mucus, which reduces sperm speed and makes sperm more difficult to reach egg if and when ovulation occurs. In the case of fertilization of the egg, the progestin tends to prevent implantation, which means that a woman naturally suppresses fertilized eggs.

It is important to realize that IUD is not considered a method of controlling the contraception of the barrier, even if it provides a barrier of species. This will not protect against sexually transmitted diseases (STD) and some studies suggest that IUD may increase the risk of HIV contraction. It is therefore extremely important to continue using the contraception of the barrier, such as the condoms of men or women to not only prevent pregnancy but alsoprevented the contraction of the STD.
