Skyla is slightly smaller than the other two IUDs on the market and is designed to protect against pregnancy for up to three years, a shorter time frame than the others.
This shorter time frame may make Skyla more attractive to younger women who think they may want to get pregnant relatively soon, some experts say, although any IUD can be removed at any time.
"More providers are spreading the word that it's okay, and more young women are demanding it," says Eve Espey, a professor of obstetrics and gynecology at the University of New Mexico.
