Comparison Between Human Sperm Preservation Medium and TEST‐Yolk Buffer on Protecting Chromatin and Morphology Integrity of Human Spermatozoa in Fertile and Subfertile Men After Freeze‐Thawing Procedure

Abstract excerpt

The aim of this study was to identify the detrimental effect of the freeze-thaw process on chromatin integrity and morphology of human spermatozoa, and to determine whether human sperm preservation medium (HSPM) or TEST-yolk buffer (TYB) offers a better protection to spermatozoa from cryodamage after the freeze-thaw procedure. Thirty-five semen samples obtained from couples childless because of male factor...
