Efficacy of sperm wash media in improving sperm motility.

Spermatozoa from 15 fertile men were washed with Ham's F10 and incubated with two commercially available sperm nutrient media for 2, 4, 6, and 24 h. Both sperm capacitation medium (Irvine Scientific Co., Santa Ana, CA) and Pro-ception (Milex Products, Inc., Chicago, IL) proved to be capable of improving sperm motion characteristics. These media may be used for incubating sperm for intrauterine insemination or for in vitro fertilization.
