Increased testicular germ cell tumor incidence (TGCT) in 129 and L1 mice exposed in utero to cyclophosphamide (CP) or radiation.

aValues given as absolute number and percentage of mice, testes, or tumors analyzed.bData from 129S5 and 129S1/SvImJ mice were pooled.cSignificantly different between treated and control mice (PdSignificantly different between CP-exposed and irradiated mice of the same strain (PeThe odd number is due to the presence of only one testis in one of the mice analyzed, which was not considered for bilateral TGCT analysis.fSignificantly different between treated and control mice (Pt test).gData from a previous study [5] were included for comparison.
