Male subfertility and the outcome of intrauterine insemination

Abstract

Seven out of 27 infertile women conceived by intrauterine insemination (IUI, 26%), one of them twice. Three other pregnancies occurred spontaneously after the discontinuation of treatment. A comparison of the data obtained from 65 treatment cycles revealed that the number of motile spermatozoa per ml of ejaculate and per ml of medium after swim-up preparation was higher in the ultimately fertile group as compared to the patients who failed to conceive. It is concluded that male subfertility affects the outcome of IUI unfavorably.
