FIG. 4.
Weights, hormone levels, and sperm counts in AF5q31−/− and control mice. (A) Testes from 24-week-old AF5q31+/+ (left) and AF5q31 −/− (right) male mice. (B to E) Weights of body and urogenital tracts of 12-week-old AF5q31+/+, AF5q31+/−, and AF5q31−/− male mice. (F to H) Serum testosterone, LH, and FSH levels in AF5q31+/+ and AF5q31−/− male mice. (I) Numbers of sperm cells prepared from 12-week-old AF5q31+/+, AF5q31+/−, and AF5q31−/− male mice. The data are given as averages. Error bars represent standard errors. Statistical significance (*, P < 0.01) in each assay was assessed using Student's t test between the wild-type and AF5q31−/− mice.
