A quantitative histological analysis of ovaries from 8- to 10-day-old wood lemmings revealed significant differences between females with X*Y and X*X sex chromosome constitutions. The ovarian volume of X*Y females was on average 57% of X*X, and the number of oocytes was less than half in X*Y compared to X*X. However, the frequency of growing oocytes in relation to the total number was 6.5% for X*Y compared to 3.0% for X*X. Oogenesis in X*Y wood lemmings resembles in many respects that of mice heterozygous for certain translocations and with tertiary trisomy (Ts31H), and those with X0 monosomy. The fertility in X*Y wood lemmings is not reduced. On the contrary, X*Y females have a higher reproductive fitness than X*X and XX. This is discussed in relation to the present findings. The body weight at birth was 8% higher in X*Y than in X*X.
