Background: Because oxidative stress can induce decreased quality of caprine semen during the storage, there has been limitation for the use of stored semen in the assisted reproductive technologies. The present study, therefore, assesses the potential of Annona muricata (A. muricata ) to reduce semen storage associateddamages. Methods: Semen was collected by electro-ejaculation from ten bucks, and extended with Tris-egg yolk (TEY) supplemented with A. muricata leaf aqueous extract (SAE) at 20 (SAE20), 40 (SAE40), and 80 (SAE80) μg/mL. Sperm variables including motility, motion characteristics, viability, membrane functionality, and DNA integrity were assessed at different storage periods (6, 24, 48, and 72 hr). In addition, oxidative stress indicators in the extender supplemted with SAE were also assessed for each group. Results: By adding SAE at 80 μg/mL in TEY, the storage of goat buck semen was improved, resulting in reduced loss of sperm motility, viability, DNA fragmentation, and membrane integrity during chilled storage at 4℃ for up to 72 hr. In addition, enrichment of TEY extender with SAE significantly (p < 0.05) reduced malondialdehyde, an indicator of oxidative stress, compared to the negative control. Conclusions: Supplementation of SAE in TEY extender can reduce buck spermatozoa liquid storage associated damages due to oxidative stress.
