The GyneFix is a modern type of intrauterine device (IUD). It consists of 4 or 6 small copper beads on a plastic string, lacking the frame of traditional IUDs. It was designed to be superior to older IUDs by containing less copper and being less-easily expelled from the womb. Studies have shown that its effectiveness in preventing pregnancy is comparable to that of the contraceptive pill; it usually does not increase the length or heaviness of menstrual periods as older IUDs did; and it is more suitable for women whose uterine sounds have revealed a small uterus, and by extension more widely accepted as an appropriate form of contraception for nulligravid women (women who have never been pregnant). The GyneFix can be inserted into the womb at the same time that an abortion is performed, due to the way it is fixed within the womb, resulting in immediate protection against further unwanted pregnancy.

Alternatives to the GyneFix include the Paragard, a copper IUD, and Mirena, a hormonal IUS offering a low dose of progesterone.

Although rapidly gaining popularity in Europe, the GyneFix is not yet available in the USA.
