Abstract: Fallopian tubal sterilization is one of the most useful ways of reproductive age women for family planning in China. However, tubal ligation is a trauma surgery with some complications and sequelae. Its acceptability is poor. Therefore, the efficient, safe, reversible, minimally invasive or non-invasive female contraceptive method is the focus of the current study, such as the intra-tubal device （ITD） with less adverse reaction and complications. The procedure of ITD placement is a non-invasive surgery. If the ITD is removed, the users will be able to restore their fertility again. ITD may be possible to replace the traditional tubal ligation and to provide a new, non-invasive and reversible contraceptive for women of reproductive age.
