Pyriproxyfen Disrupts the Ongoing Spermatogenesis Wave in Danio rerio Potentially Mediated by Voltage‐Dependent Calcium Channels and Protein Kinase C

Journal of Applied Toxicology, Volume 45, Issue 9, Page 1705-1719, September 2025.
ABSTRACT Pyriproxyfen (PPX) is an analog of the juvenile hormone from insects. Following our previous studies, for the ex vivo short‐term effect, we chose 10−9 M pyriproxyfen to analyze the morphology of spermatogenesis wave cells.
