Popis: Background: Recent studies have supported the beneficial effects of a short abstinence period on sperm parameters. The aim of this study was to assess sperm motility, morphology and DNA fragmentation before and after swim-up of a second ejaculate obtained after a short abstinence period in normozoospermic men and oligo-astheno-teratozoospermic (OAT) patients. Material and methods: Semen analyses and swim-up preparations of two consecutive semen samples (collected within 1 h) were carried out in 30 normozoospermic and 35 OAT patients enrolled in an assisted reproductive technique (ART) program. Results: Compared to the first ejaculate, the second sample showed a higher percentage of spermatozoa with normal form (p <
0.01) and lower percentage of spermatozoa with DNA fragmentation (p <
0.01) in normozoospermic men, whereas a higher percentage of spermatozoa with progressive motility (p <
0.001) and normal morphology (p <
0.0001) was found in OAT patients. Swim-up separation showed a lower DNA fragmentation rate (p <
0.05) in the second ejaculate in normozoospermic men, whereas the second ejaculate of OAT patents showed an increase in normally-shaped spermatozoa (p <
0.01) and lower percentage of spermatozoa with fragmented DNA (p <
0.001) compared to the first one. Conclusions: Swim-up separation of a second ejaculate collected within 1 h might be suggested for ART procedures, especially in OAT patients.
