Description:
Chemical mutagenesis test results ave not revealed evidence of germ-line specific mutagens. owever, conventional assays have indicated that there are male-female differences in mutagenic response, as well as quantitative/qualitative differences in induced mutations which depend upon the particular cell-stage exposed. any factors inherent to the germ-line can be speculated to influence chemical transport to, and interaction with, target cell populations to result in mutagenic outcomes. he level of uncertainty regarding the general operation of such actors, in combination with the limited availability of chemical test data designed to-address comparative somatic and germ cell mutagenesis, leaves open the question of whether there are mutagens specifically affecting germ cells. his argues for a conservative approach to interpreting germ cell risk from somatic cell mutation analysis.
