Comparison of intrauterine insemination and in vitro fertilization for the treatment of unexplained infertility

This retrospective study was performed to compare the pregnancy rates (PR) in patients treated with either in vitro fertilization (IVF) or controlled ovarian superstimulation (COS) and intrauterine insemination (IUT) in patients with unexplained infertility. In Group A, 77 females underwent 125 treatment cycles of IVF; in Group B, 54 females underwent 131 treatment cycles of COS and IUI. pregnancy rates per cycle initiated in Group A and Group B were 17.6% and 19%, (P>0.05). We concluded that COS and IUI are as effective as IVF in patients with unexplained infertility.
