Abstract
The aim of this study was to evaluate motility, viability, DNA integrity and apoptosis of
spermatozoa when washed semen samples were kept for up to 12 days at 4–6°C and
25°C. In this experimental study, 26 normozoospermic semen samples were washed
twice in Modified Ham's F10 and resuspended in IVF fertilisation medium. Half of the
specimens were stored at 4–6°C, and the other half was kept at 25°C for 12 days. The
proportions of viable, motile, spermatozoa with double-stranded DNA and apoptotic
spermatozoa were examined during storage time. Apoptosis was measured using annexin
V-PI staining followed by flow cytometry. Results showed that sperm motility
and viability decreased during 12 days of sample storage (p < .001). There was no
significant difference between the two temperatures in terms of motility and viability
for up to 2 days (p < .05).
