Intrauterine insemination (IUI) does not improve pregnancy rates in infertile couples where semen parameters are normal and postcoital tests are adequate.

PURPOSE: To determine if intrauterine insemination (IUI) improves pregnancy rates in couples with a correctable ovulatory defect but a male partner with an apparent normal semen analysis and a normal postcoital test.

MATERIALS AND

METHODS

A prospective evaluation of clinical live delivered pregnancy rates following the first cycle where follicular maturation was demonstrated naturally or with a follicle maturing drug. The couples were given the option of IUI.

RESULTS

The live delivered pregnancy rates per IUI cycle were similar with intercourse only vs addition of IUI (18.7% vs 21.4%).

CONCLUSIONS

There is no evidence to support the notion that IUI improves pregnancy rates in circumstances where the semen analysis and postcoital tests are normal.
