title: Should we continue performing intrauterine inseminations in the year 2004?
abstract: This review summarizes the existing evidence regarding intrauterine insemination (IUI) as a treatment for cervical hostility, male and unexplained subfertility. IUI in natural cycles has been proven effective in patients with cervical hostility and moderate male subfertility. IUI in cycles with mild ovarian hyperstimulation (MOH) should be the treatment of choice in couples with mild male subfertilty (average total motile sperm count above 10 million) and unexplained subfertilty. When MOH is applied, gonadotropins have been proven more effective compared with clomiphene citrate. Further large trials comparing clomiphene citrate with gonadotropins are mandatory. Prevention of multiple pregnancies in MOH/IUI programs is of paramount importance. A strategy with a low-dose step-up protocol and strict cancellation criteria is proposed. When multiple pregnancies are kept to a minimum, MOH/IUI is more cost-effective compared with in vitro fertilization and embryo transfer. Future research should focus on prediction models to predict the outcome of MOH/IUI treatment for individual couples before starting treatment.
