Spermatozoa cryopreservation protocols have been proven for yellow catfish (Pelteobagrus fulvidraco), but cryopreservation can still induce mobile destruction and have an impact on spermatozoa viability and fertility. hence, the goal of the paper was to evaluate the consequences of including or not adding cryoprotectants through low-temperature storage within the ultrastructural harm, oxidative harm, and DNA harm of thawed yellow catfish spermatozoa. The blended semen of a few male yellow catfish was divided into a clean spermatozoa team, a frozen spermatozoa group (DMSO+) using a cryoprotectant (10% DMSO), along with a frozen spermatozoa group with no cryoprotectant (DMSO−). Ultrastructural on the spermatozoa soon after thawing were observed under an electron microscope along with the spermatozoa were being assayed for SOD, MDA, and T-AOC enzyme things to do, along with for DNA integrity.
