Abstract


The study was carried out on 28 white Wistar adult female rats from F1 generation (derived from females and males exposed for three months before mating to potassium dichromate, 25, 50 and 75 ppm CrVI). F1 generation was exposed in utero and until sexual maturity to the same Cr VI levels. The study pointed out: significant increase of sexual cycles duration comparative to control group and over the physiological limits, directly correlated to exposure level (p<0.01); changes in regularity of sexual cycles, respectively: significant (p<0.01) decrease of proestrus, estrus and diestrus percentages in physiological limits as duration and inversely correlated to exposure level, appearance of sexual cycles with absent proestrus and estrus, directly correlated with the exposure level (p<0.01) and of prolonged diestrus, directly correlated to exposure level, (p<0.01).
