    Heritable mutations in the male germline can lead to genetic changes affecting future generations and disease risk.

  • 2

    DNA damage during spermatogenesis can result from both endogenous processes and exogenous environmental exposures.

  • 3

    The comet assay is a validated method for measuring DNA damage, but standardized assays for germ cell mutagenicity are limited.

  • 4

    A modified comet assay protocol was developed to selectively assess DNA damage in rat testicular germ cells.

  • 5

    The study aimed to evaluate the applicability of the germ cell comet assay using direct-acting genotoxicants like X-ray and EMS.
