For unexplained infertility, stimulated IUI cycles improve pregnancy rates, but aiming for a maximum of two ovulatory follicles with strict hCG criteria optimizes results while minimizing twinning.

This chapter discusses ovarian stimulation strategies used with intra-uterine insemination (IUI) for women with mild male factor infertility or idiopathic (unexplained) infertility, focusing on how stimulated versus unstimulated cycles affect pregnancy and multiple pregnancy outcomes. It reports that for pure mild male factor infertility, stimulating the ovaries makes very little difference to results, whereas in unexplained infertility stimulated IUI cycles improve pregnancy rates compared with unstimulated cycles, but can increase multiple pregnancy rates. The author’s approach with gonadotrophin stimulation aims for a maximum of two ovulatory follicles using strict criteria for hCG administration to optimize outcomes while minimizing twinning. This paper does not explicitly discuss endometriosis or adenomyosis; it was included in the corpus via a keyword match in the upstream search index.

Abstract

When intra-uterine insemination (IUI) is chosen for the treatment of mild male factor infertility or idiopathic (unexplained) infertility, there are a number of options for ovarian stimulation for these women who are usually ovulating spontaneously. There is now general agreement that for pure mild male factor infertility (sperm concentration 5–15 million/ml and/or progressive motility 20–32 %), whether the ovaries are stimulated or not before IUI makes very little difference to the results. For unexplained infertility, stimulated cycles in combination with IUI are more effective than unstimulated cycles as regards pregnancy rates. The combination of IUI with stimulated cycles, although improving pregnancy rates, is often accompanied by unacceptable multiple pregnancy rates. With ovarian stimulation with gonadotrophins, I aim to achieve a maximum of two ovulatory follicles and this with strict criteria for administering hCG seems to give optimal results with minimal twinning rates.
