(18), 2652; (registering DOI) - twelve Sep 2024 Abstract Spermatozoa cryopreservation protocols are actually founded for yellow catfish (Pelteobagrus fulvidraco), but cryopreservation can still lead to cellular destruction and impact spermatozoa viability and fertility. thus, the goal of this paper was to evaluate the results of incorporating or not incorporating cryoprotectants [...] browse far more. Spermatozoa cryopreservation protocols are actually founded for yellow catfish (Pelteobagrus fulvidraco), but cryopreservation can nonetheless result in mobile problems and influence spermatozoa viability and fertility. for that reason, the aim of the paper was To guage the effects of incorporating or not incorporating cryoprotectants during minimal-temperature storage about the ultrastructural problems, oxidative injury, and DNA damage of thawed yellow catfish spermatozoa. The combined semen of 3 male yellow catfish was divided into a new spermatozoa group, a frozen spermatozoa team (DMSO+) which has a cryoprotectant (ten% DMSO), and also a frozen spermatozoa team without a cryoprotectant (DMSO−). Ultrastructural on the spermatozoa right after thawing ended up observed underneath an electron microscope as well as the spermatozoa were being assayed for SOD, MDA, and T-AOC enzyme things to do, together with for DNA integrity.
