In 1960, the first model of the double-S contraceptive IUD named the “Lippes loop” was released. The Lippes loop was a flexible polyethylene plastic loop with a trapezoidal shape that Dr Lippes believed fit closely to the contours of the uterine cavity, to reduce the risk of expulsion.
In 1960, Jack Lippes made the first model of his ‘Double-S” Intra uterine Contraceptive Device -Lippes Loop (LL), a flexible polyethylene plastic loop of appropriate size for the uterine cavity which subsequently went on to become the standard for other IUD’s to be compared with [1, 2].
The result was the plastic double “S” loop—a trapezoidal-shaped IUD that closely fit the contours of the uterine cavity, thereby reducing the incidence of expulsion. First distributed in 1962, the Lippes Loop quickly became the most widely prescribed IUD in the United States.
A 74-year-old woman had a Lippes Loop IUD inserted 50 years ago and was admitted for urinary incontinence. The IUD was removed and no complications were found. The article reviews the history, complications and literature of this IUD type.
Learn about the origins and evolution of intrauterine devices (IUDs), a form of long-acting reversible contraception (LARC). The web page covers the development of the Lippes Loop, a plastic double S-shaped device, and its popularity and impact.
Dr Jeffrey Peipert, Deputy Editor for AJOG, discusses the evolution and current status of the IUD in women’s health care in the accompanying editorial in this month’s issue, “Lippes loop and the first IUDs: lessons from a bygone era.”
IUD and all long-acting reversible contraceptive methods offer powerful protection and change the default. As Jack Lippes put it, “By having an IUD inserted, the responsible act of parenthood became an act of deliberation.”1 No, the IUD is not the perfect method for all women. The best contraceptive method is the one that the couple will use

Lippes Loop is a plastic intrauterine contraceptive device invented by Jack Lippes, an obstetrician-gynecologist in the 1950s. It was the first IUD to fit the uterine cavity well and reduce expulsion, and it became the standard against which other IUDs were compared.
The result was the plastic double “S” loop—a trapezoidal-shaped IUD that closely fit the contours of the uterine cavity, thereby reducing the incidence of expulsion. First distributed in 1962, the Lippes Loop quickly became the most widely prescribed IUD in the United States.
