Abstract | dc.description.abstract | Clinical evaluation of the contraceptive effectiveness of the endouterine copper "T" has been extended to include "T" devices bearing copper wire having surface areas of 120 mm.2 and of 200 mm.2 copper, respectively. Within the range studied, the antifertility effect increases as the area of the exposed surface of copper is increased. At the end of one year, the TCu-120 resulted in a pregnancy rate of 2.0 per 100 users and a continuation rate of 94.1 per cent. Results from 7 months of observation with the TCu-200 showed a pregnancy rate of zero and a continuation rate of 98.3 per cent. © 1971. | |
