Ortho‐phenylphenol (OPP), as an active ingredient of disinfectants, has been worldwide utilized as fungicides and antibacterial agents in hospital, agriculture, wood preservation, and veterinary products. However, little is known about the toxic effects of OPP on male reproduction, especially sperm motility, and the underlying mechanisms. In this study, we chose porcine sperms as in vitro model to investigate the effects and mechanisms of OPP exposure on sperm motility. Our results indicated that porcine sperm motility decreases significantly in a dose‐dependent manner after exposed to OPP. Additionally, ATP synthesis deficiency was revealed by downregulation of ATP synthase subunit beta and adenosine 5′‐monophosphate‐activated protein kinase expression. Furthermore, OPP disturbed the expression of TP53 and PTEN, which contributed to AKT pathway deactivation. OPP exposure also disrupted platelet‐derived growth factor receptor A expression, which further inhibited 3‐phosphoinositide‐dependent protein kinase 1 activation, resulting in protein kinase B and pyruvate dehydrogenase phosphatase catalytic subunit 1 deactivation. In conclusion, these observations suggest that OPP exposure decreases porcine sperm motility by disturbing the AMPK/AKT signaling pathway. Environ. Mol. Mutagen. 2019. © 2019 Wiley Periodicals, Inc.
