Table 1.

Acrosomal exocytosis of sperm traveling through the cumulus cells matrix. Data represent 26 experiments (n=26). Average residence time is expressed as the mean ± SEM. AI: acrosome-intact sperm; AR: acrosome-reacted sperm.

Average residence time of AI sperm in the COCs (min) 7.1 ± 2.2
Average residence time of AR sperm in the COCs (min) 26.4 ± 4.8
Total number of sperm that entered the COCs in 90 min 233 (100 %)
Number of AI sperm that entered the COCs 166 (71.3 %)
Number of AR sperm that entered the COCs 67 (28.7 %)
Total number of sperm that underwent AE within the COCs 8 (4.8 %)
Rate of AE in HTF medium (%/ hour) 10
Rate of AE in cumulus matrix (%/ hour) 7
