There are women who find it inconvenient not taking the pill daily, but for many other yes, what follows that notwithstanding their safety, do not suit the need of women. IUDs have reached high fees clinical efficacy and safety for use in any group of women, including gilts.
Methodology: A search for original articles and systematic reviews published in the last ten years in the PubMed database, specifically study reversible long-term hormonal contraception was made. They were included in the various search engines, the words: Long-Acting Reversible Contraception, intrauterine contraceptive method, contraceptive implants and intrauterine, myths About IUDs, and others. We selected the highest level of evidence and documents were analyzed and 76 of these myths and realities were located around the long-term contraception.
