Arbutin Preserves Boar Sperm During Storage at 17°C by Enhancing the Antioxidant Capacity via the NRF2/GPX4 Signalling.

Arbutin is a naturally present antioxidant derived from plants. The objective of this study was to examine the effect of arbutin on boar sperm during storage at 17°C and the underlying mechanisms. Our results showed that the addition of arbutin to extenders markedly enhanced the sperm (progressive) motility and plasma membrane and acrosomal integrity on Days 9 and 13 of preservation (p < 0.
