Cytogenetic analysis of germ-line cells prior to intracytoplasmic sperm injection (ICSI) treatment is thought to be necessary for infertile males with an identified chromosomal abnormality. We analyzed the chromosomal karyotype of human spermatozoa from an oligoasthenozoospermic carrier of a reciprocal translocation t(10; 21). Cytogenetic analysis of 39 spermatozoa was performed by spectral karyotyping...
Phosphatidylserine membrane translocation (PST) is considered to be a marker of apoptosis; however, numerous studies have reported on its role in processes not related to cell death. The purpose of the study was to investigate: (1) what is the impact of PST on the motility of spermatozoa, and (2) does the swim-up isolation involve the percentage of cells presenting PST? Semen of 28 normozoospermic...
The aim of this study was to investigate the relationship between apoptotic markers present in human spermatozoa, namely phosphatidylserine translocation (PST) from the inner to the outer layer of the cytomembrane and the active form of caspase-3 (c3) versus the fertilizing potential of male gametes in conventional in vitro fertilization (IVF) and intracytoplasmic sperm injection (ICSI) models. A...
