Abstract
- Ethylene oxide (E.O) is an epoxide compound, and it has been utilized as a sterilizer or production of ether compounds in several industries. Although the toxic effects of E.O on bacteria and mammals have been reported, its effects on male reproductive toxicity during sperm capacitation are not fully understood. Therefore, this study was designed to evaluate the effects of E.O exposure during sperm capacitation. Boar spermatozoa were treated with various E.O concentrations (0, 0.1, 1, 10, and 100 μМ). After exposure, sperm motility, motion kinematics, capacitation status, intracellular ATP levels, cell viability, expression levels of protein kinase A (PKA) activation, and tyrosine phosphorylation were evaluated. Results revealed that E.O exposure significantly decreased sperm motility, motion kinematics, and intracellular ATP levels but significantly increased the capacitated spermatozoa. In addition, the PKA activation and tyrosine phosphorylation were abnormally changed. According to our results, E.O may cause toxic effects on sperm function during capacitation, which induces male reproductive toxicity. Consequently, we suggest that male reproductive toxicity should be considered when using E.O.<br />Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper.<br /> (Copyright © 2024 Elsevier Inc.
