Our recent findings have revealed that such defects may be linked to the molecular chaperone, heat shock protein A2 (HSPA2), due to its ability to facilitate the formation of multimeric zona pellucida (ZP)-receptor complexes on the surface of human spermatozoa. This study aimed to examine the impact of oxidative stress on the formation of these Z...
