The IUD in this case was behind the placenta and was removed during the childbirth. Of plastic material, the piece has a T shape and is placed inside the uterus. There are also two types of method: one is made of copper and the other has a load of hormones.
"There are several explanations for the mechanism of action of the copper IUD. The most accepted are that a foreign body reaction occurs This prevents gestation in two ways: one by hindering the passage of sperm through the cervix and uterine cavity (fertilization occurs in the tubes), and the other is that if fertilization occurs, the fertilized egg can not implant or even a toxic effect directly on the egg, "says the gynecologist Fabio Laginha." The medicated IUD already releases a hormone (levonorgestrel), which atrophies the internal lining of the egg. This prevents atrophy of the sperm from reaching the fallopian tubes (much more effectively than the copper IUD) and, if fertilization occurs, it can not be fixed in the uterine cavity. and it will decrease the amount of menstrual bleeding, and it can stay without menstruating in more than 40% of users, as well as slow down the colic and have a greater contraceptive effect. "
The amount of hormone released into the bloodstream by this IUD is about two progesterone-based birth control pills per month. It can be used by teenagers or women who do not get pregnant. Along with implants, male sterilization (vasectomy) and female (tubal ligation), the risk of a patient becoming pregnant is very small, about one case in 500 women in use per year. "IUDs are great options for those who want a long-term reversible method and are unable or unwilling to use pills because of reactions and / or interactions with hormones such as thrombosis, anticonvulsant drugs, certain types of hormone-dependent cancers, "says Laginha.
The study in question reviewed 26 research on the subject. And it says evidence has been found that consuming up to four units of alcohol per week may be associated with a high risk that the baby will be born prematurely. But the scientists say the data are inconclusive. According to Bristol University Medical and Community College specialist Loubaba Mamluk, doctors are surprised that this fact has been so poorly researched by the medical community.
After three years without registered cases of measles in Brazil, the Secretary of Health of Roraima reported that a case is being investigated in the state. However, the Ministry of Health reported on Wednesday (21) that Brazil remains free of measles and confirmed that the case in Roraima was "imported" from Venezuela.
