Abstract
Antioxidant nanoparticles include the potential for improving sperm cryopreservation. The aim of performing this study was to evaluate the effects of gamma-oryzanol (GO) at 0 (C) (control group), 20 (GO20), 40 (GO40), 60 (GO60), 80 (GO80), and 100 (GO100) µM and gamma-oryzanol nanoparticles (GON) at 0 (CN), 20 (GON20), 40 (GON40), 60 (GO60), 80 (GON80), and 100 (GON100) µM on post-thawed sperm quality and fertility of rooster sperm. Sperm motility, plasma membrane integrity, total abnormality, mitochondrial activity (Rhodamine 123), apoptotic features (Annexin V/Propidium iodide), reactive oxygen species (ROS) production, ATP content and the fertility and hatchability were evaluated after thawing. Total motility in GON60 and GON80 were significantly higher compared to control groups (C and CN). GON80 showed the greatest percentages of progressive motilities. When GO80, GON60, and GON80 were added to the cryopreservation medium, the plasma membrane functionality of the semen samples improved. The minimum abnormality of spermatozoa is observed in the group treated with GON80. The groups treated with GON60 and GON80 had greater (P < 0.05) mitochondrial activity. The level of sperm ROS after cryopreservation was significantly lower in GON60 and GON80 groups. Live sperm was significantly higher (P < 0.05) in GON60 and GON80 group compared to other groups. GON60 and GON80 groups also led to the lowest significant percentage of apoptosis-like change sperm. Greater fertility percentages were observed (P < 0.05) when sperm were stored in extenders treated with GON60 and GON80. GON80 resulted in significantly improved hatched eggs compared to C, GO60, GO180 and CN. In conclusion, supplementation of Lake extender with 60 and 80 µM gamma-oryzanol nanoparticles could be a proper process to improve freeze-thawing rooster sperm quality leading to better freeze/thaw characteristics.
