Both HOST and TUNEL assay were performed for each sample. The sperm swelling pattern<br>and positive apoptosis staining of individual spermatozoa were evaluated. HOST and TUNEL scores, and the<br>proportion of positive staining in each grade were calculated in each sample.<br><strong>Results</strong>: The results showed a negative correlation between HOST and TUNEL scores (r = -0.428, P = 0.026). Sperm<br>swelling grade A had a higher incidence of positive apoptosis staining when compared with other grades (P < 0.01).<br>There was no statistically significant difference in positive apoptotic staining between other grades; nevertheless,<br>sperm swelling grade D tended to have a lower incidence of positive apoptosis staining.<br><strong>Conclusion</strong>: Based on the results of this study, HOST may be used as an optional test to identify DNA-intact<br>spermatozoa whereby sperm with a grade D swelling pattern should be selected preferentially for intracytoplasmic<br>sperm injection (ICSI), whereas sperm with a grade A swelling pattern should be avoided for ICSI.</p>}, number={1}, journal={Siriraj Medical Journal}, author={Laokirkkiat, Pitak and Jareemit, Nida and Thanaboonyawat, Isarin and Smith, Hollie and Sriiam, Sukanya}, year={2019}, month={Feb.}, pages={8–13} }
