摘要：
A comparative analysis of the parameters characterizing sperm apoptosis of young (27-42 years) and middle-aged (44-51 years) men was performed by flow cytometry. Irrespective of age, activity of caspase-3 and p53-mediated controlling the transmission of apoptogenic signal transmission in gametes remained stable with the formation of germ cells with delayed (p<0.05) cell death according to the Annexin V-FITC+PI- criterion (predominantly in middle-aged men). Inhibition of the transmission of a proapoptogenic stimulus mediated by membrane cell death receptors (FAS) was also observed in this group. Comparison of indicators of sperm apoptosis showed age-related features of cell death, in particular, inhibition of membrane reception triggering FAS-dependent apoptosis, which is associated with insufficient phosphatidylserine production in middle-aged men, excessive life cycle duration, and aging of spermatozoa.
