2-Naphthylamine (NAP) is recognized as a carcinogen primarily associated with bladder cancer, with exposure mainly through cigarette and E-cigarette smoke. Recent research suggests NAP may also cause testicular damage, including atrophy and tissue hyperplasia, potentially affecting spermatogenesis.
This explainer discusses the possible mechanisms by which NAP impacts testicular immunity and the implications for male reproductive health, emphasizing the importance of reducing exposure to this chemical.
