Влияние различных факторов на параметры эякулята человека In vitro

The paper presents the results of investigations dealing with the impact of experimental exposures (to chemical substances and electromagnetic radiation) on human sperm. The radiation is shown to suppress sperm motility. High hydrogen peroxide concentrations and ejaculate cryopreservation have also a negative effect on sperm motility and viability. Low hydrogen peroxide levels cause the opposite effect on sperm motility. The use of some regulatory mechanisms also yields positive results. Antioxidants increase the number of mobile sex cells in an experiment. Clinical observations using antioxidants support the results of laboratory tests.
