Abstract

The influence of males on two measures of reproductive activation was investigated in female montane voles (Microtus montanus) in the laboratory. Females housed with males from weaning at 18 days of age exhibited earlier vaginal opening and earlier vaginal cornification than females introduced to males on day 38. The responses of weanling females housed across a wire-mesh barrier from males were intermediate to those of the other two groups.
