Comparison of controlled ovarian superstimulation with or without intrauterine insemination for the treatment of unexplaned infertility

ABSTRACT

This retrospective study was performed to compare the pregnancy rates [PR] in patients treated with either controlled ovarian superstimulation [COS] and intrauterine insemination [IUI] or COS and timed intercourse [TI] in patients with unexplained infertility. Fifty-seven females underwent 98 treatment cycles of COS and IUI and 30 females underwent 96 treatment cycles of COS and TI. Pregnancy rates [PR] per cycle in the groups treated with COS and either IUI or TI were 18.4% and 3.1% respectively [P<0.05]. We concluded that COS and IUI are an effective treatment compared with COS and TI in patients with unexplained infertility
