History

The hormonal IUD was also invented in the 1960s and 1970s; initially the goal was to mitigate the increased menstrual bleeding associated with copper and inert IUDs. The first model, Progestasert, was conceived of by Antonio Scommegna and created by Tapani J. V. Luukkainen, but the device only lasted for one year of use. Progestasert was manufactured until 2001. One commercial hormonal IUD which is currently available, Mirena, was also developed by Luukkainen and released in 1976. The manufacturer of the Mirena, Bayer AG, became the target of multiple lawsuits over allegations that Bayer failed to adequately warn users that the IUD could pierce the uterus and migrate to other parts of the body.
