Decondensation of chromatin state in human sperm cells after cryopreservation and electromagnetic irradiation of millimeter range
Abstract
In the work investigated the effects of electromagnetic irradiation of millimeter range of 0.03 mW/cm2
density on cryopreserved human sperm in normal and pathological state. Morpho-functional state of sperm before and after irradiation was assessed using light, fluorescence microscopy and FACS analysis. Application of irradiation of the samples for 15 minutes at normospermia and 5 minutes at asthenozoospermia resulted in a significant increase in 7AAD+sperm about the appropriate value in the control group. It has been found that electromagnetic irradiation of millimeter range of 0.03 mW/sm2 density on cryopreserved human sperm for 5 minutes at normospermia and 15 minutes at asthenozoospermia increases the fraction of rectilinearly moving sperm without changing the integrity of membrane, nuclear chromatin state and generation of apoptosis.
