OBJECTIVE To determine whether artificial insemination with frozen donor sperm yielded a higher pregnancy rate per cycle by intracervical (ICI) or intrauterine (IUI) techniques. A meta-analysis was performed. DATA IDENTIFICATION A computerized MEDLINE search of the English-language literature on artificial insemination with donor sperm was performed and augmented by a review of meeting abstra...
