Comparison of intrauterine insemination, intracervical insemination, and timed intercourse in women treated with human menopausal gonadotropin.

The effects of intrauterine insemination (IUI), intracervical insemination (ICI), and timed intercourse (TI) in women who were treated with human menopausal gonadotropin (hMG) for anovulation were evaluated. The pregnancy rates per cycle following IUI (70 cycles), ICI (62 cycles) and TI (158 cycles) were 20%, 9.6%, and 17.7%, respectively; these differences are not statistically significant. The abortion rate and the multiple pregnancy rate were also not significantly different. This report suggests that in women who are undergoing treatment with hMG, there is no added benefit from artificial insemination (either intrauterine or intracervical insemination) over timed intercourse.
