title: A microwell sperm penetration assay.
abstract: Egg penetration rates in a modified SPA using microwells in tissue typing plates were comparable with those in a standard assay. This technique allows sperm penetrating ability to be determined using single zona-free hamster eggs and as few as 10,000 spermatozoa.
