[The development of GS-I type contraception flower].

PIP: The development and short-term clinical tests of a new type of IUD made of silicone rubber are reported. The structure of the IUD is appropriate and the excellency of in vivo stability and aging-resistant property of silicone rubber make it contraceptively effective. All this lowers the side effects (especially menorrhagia, soreness, and other uncomfortable feelings; and makes it suitable for longterm use. The materials used to produce this flower are domestically available. The technology and equipment involved are simple, and the production can easily be popularized. (author's modified)^ieng
