The sperm penetration assay (SPA) provides valuable information on specific events of fertilization and is a potentially useful indicator of sperm fertility. Ejaculated semen from 4 boars was subjected to 3 treatments: fresh (FRE, no storage), liquid‐stored (LIS, stored at 18°C for 3 days), and frozen (FRO, frozen by pellet method and stored at −196°C for 3 days). A highly motile sperm population was isolated by the swim‐up procedure (1 hr). FRE and LIS were incubated an additional 3 hr at 39°C in a Tris‐buffered medium to elicit capacitation and the acrosome reaction. Sperm motility and acrosomal integrity were assessed before and after incubation. For the SPA, sperm and eggs were incubated at 39°C for 3 hr in Hams F‐10 medium. Each egg was assessed for sperm penetration, sperm binding, and stage of development. Percentages of sperm motility and sperm with a normal apical ridge (NAR) prior to incubation were 78 and 78 (FRE), 75 and 69 (LIS), and 28 and 50 (FRO). After incubation, percentages of motility, NAR, and acrosome‐reacted sperm were 34, 10, and 73 (FRE); 43, 24, and 51 (LIS); and 18, 13, and 59 (FRO). A somewhat higher (P < .05) percentage of ZFH ova was penetrated by FRE (45.8) than by LIS (42.0). Penetration of ZFH ova by FRO was markedly (P < .05) reduced (30.2). Sperm penetration was not significantly correlated with motility or acrosomal integrity before or after incubation, regardless of treatment. These data suggest that the SPA can be used in conjunction with conventional measures of semen analysis in assessing the potential fertilizing capacity of boar sperm and that liquid storage is superior to frozen storage with respect to preserving sperm fertility.</jats:p> Effect of liquid storage and cryopreservation of boar spermatozoa on acrosomal integrity and the penetration of zona‐free hamster ova in vitro Gamete Research |
