Postabortion insertions of the pleated membrane.
The pleated or intrauterine membrane (IUM) was designed to fit a range of uterine sizes and shapes and to adjust to transient changes resulting from uterine motility. The retention and contraceptive abilities of postabortion IUM insertions are analyzed in this study of 154 IUM insertions made within 3 days of treatment for an incomplete or inevitable abortion. Results indicate low 1-year net cumulative event rates for pregnancy (1.7 per 100 users), expulsion (7.2 per 100 users), and removal for bleeding and/or pain (3.9 per 100 users). These rates were similar to those reported in  a study of interval insertions of the IUM; moreover, these results also compared favorably with corresponding rates of postabortion insertions reported in studies using other devices. Thus, the postabortion period is indicated as being an effective time for IUM insertion.
