A RANDOMIZED COMPARATIVE-STUDY OF THE TCU380A AND CU-SAFE 300 IUDS

The Cu-Safe 300 is one of the latest additions to the array of availab le IUDs. It was specifically designed to decrease unwanted side-effect s (e.g. bleeding, pain and expulsion) while providing simplicity of in sertion, ease of removal and fair contraceptive protection. For compar ison, the TCu380A was chosen. Both types were inserted at random in 60 0 recipients by a group of independent physicians with a long standing experience in intrauterine contraception. Life table analysis was use d for comparison over a period of three years. The Cu-Safe 300 produce d a slightly but not statistically significant higher pregnancy rate a nd more expulsions. Removals for bleeding and pain, however, were sign ificantly less frequent. All inserting physicians agreed that insertio n and removal of this new device was remarkably easy.
