Influence of the number of motile spermatozoa inseminated and of their morphology on the success of intrauterine insemination

Abstract

Our results show that a minimum of 5 x 10(6) motile spermatozoa should be inseminated when the normal morphology of the sperm after preparation is < 30%; the quantity compensates at least in part for the defective quality. If this threshold of NMSI cannot be obtained, IVF should be recommended.
