This study investigated the relationship between acrosome reactions and fatty acid composition with respect to fertility in boar sperm. The acrosome reaction was induced more than 85% by 60 mM methyl‐beta‐cyclodextrin (MBCD), and plasma membrane integrity was significantly reduced dependent on the MBCD level in boar sperm (p < .05). The acrosome‐reacted sperm exhibited significantly higher saturated fatty acids (SFAs) and lower polyunsaturated fatty acids (PUFAs) composition compared to the non‐acrosome reaction group (< .0001). In addition, the PUFAs, C22:5n‐6 (docosapentaenoic acid [DPA]; p < .01) and C22:6n‐3 (docosahexaenoic acid [DHA]; < .0001) were significantly decreased, and cleavage and blastocyst formation of oocytes were significantly (< .0001) decreased in acrosome‐reacted sperm relative to non‐acrosome‐reacted sperm. Moreover, acrosome reaction was positively correlated with SFAs, whereas negatively correlated with PUFAs, of the PUFAs, the DPA (p = .0005) and DHA (= <.0001) were negatively correlated with the acrosome reaction. Therefore, these results suggest that the PUFAs composition of sperm is closely involved in acrosome reaction in pigs.
