An evaluation of the performances of copper T 380A (TCU 380A) and multiload copper 375/250 (MLCU 375/250) intrauterine contraceptive devices (IUCDS) was carried out at University College Hospital, Ibadan, Nigeria (UCH) in a clinical comparative trial. The IUCDS showed similar low vent rates at one year of continuous use. The difference in cumulative net probabilities for termination due to pelvic inflammatory disease was weakly significant at the sixth month of follow up with MLCU 250 having the highest rate. (TCU 380A-0%; MLCU 375-0%; MLCU 250-3.1%; X2 = 6.0; P < 0.05). This significant difference disappeared by the twelfth month of continuous use. Likewise, the difference in cumulative net probabilities for overall termination was significant at six months and insignificant at twelve months of follow up. The continuation rate after one year were 86%, 92% and 87% respectively for TCU 380A, MLCU 375 and MLCU 250. These rates were higher than 80% and 51% quoted for the previously available Lippes loop in the same environment [1,2]. It was therefore concluded that the three IUCDS are comparable in performances in the first year of use and could be used at our family planning clinic or any other clinic in a similar setting.
