Sucralose disrupts male fertility by damaging sperm and altering hormones in animal study

Researchers found that chronic sucralose exposure in male rats disrupted reproductive hormones, damaged sperm, and impaired testicular function through oxidative stress and autophagy dysregulation. These findings raise concerns about the reproductive risks of high sucralose intake and its persistent presence in the environment.
