Table 2 Mean ± SD percentage of progressively motile spermatozoa, sperm vigour, percentage of spermatozoa with intact acrosomes and DNA damage in semen samples with low (group 1, control) and increased percentages of proximal cytoplasmic droplets (PCD, group 2) before (0h) and after 3h of incubation at 37°C
