A Comparative Analysis of the Antioxidant Profiles Generated by the RoXsta<sup>TM</sup> System for Diverse Biological Fluids Highlights the Powerful Protective Role of Human Semina...
Published 2025-01-01“…The powerful antioxidant properties of human semen were shown to reside within the seminal plasma (SP) fraction, rather than the spermatozoa, and to be resistant to snap freezing in liquid nitrogen. Moreover, comparative studies demonstrated that human SP exhibited significantly (<i>p</i> < 0.001) higher levels of antioxidant potential than any other species examined (stallion, bull, dog) and that this intense activity reflected the relative vulnerability of human spermatozoa to peroxide attack. (4) Conclusions: The RoXsta<sup>TM</sup> system provides valuable information on the antioxidant profile of complex biological fluids, supporting its diagnostic role in conditions associated with oxidative stress. …”
