A comparative study of three intrauterine contraceptive devices, the Antigon-F, the Copper-T, and the Ypsilon-Y, was carried out at The New York Hospital Cornell Medical Center during an 18-month period from March 1, 1972, through August 31, 1973. At the cutoff date of February 28, 1974, all patients had been followed for at least 6 months. During the period of study, 884 Antigon-F devices, representing 14,436 woman-months of use, were inserted. The over-all pregnancy rate was 0.88, with an explusion rate of 5.1 and a medical removal rate of 9.1/100 woman-years. This device was best tolerated by multiparous women. There was a total of 910 insertions of the Ypilson-Y, representing 14,348 woman-months of use. The over-all pregnancy rate was 1.8, with an explusion rate of 1.9 and a medical removal rate of 3.7/100 woman-years. The pregnancy rate in nulliparous women was 0.78, with a continuation rate of 88.9. The pregnancy rate in multiparous woman was higher, i.e., 2.4. Nine hundred thirty-nine Copper-T 200 devices, representing 15,558 woman-months, were inserted. The over-all pregnancy rate was 0.85, with an expulsion rate of 1.8, a medical removal rate of 4.5, and a continuation rate of 88.4/100 woman-years. The pregnancy rate was 0.82 for nulliparous women and slightly higher, i.e., 1.04, for multiparous women. Thus, all three devices had considerable merit. The Antigon-F and the Copper-T seemed the best in multiparous women; the Ypsilon-Y in the size used was best in nulliparous women. The only perforations occurred with the Copper-T.
