Leuprolide exposure during the periadolescent period had no effect on interest in the male stimulus during the partner-preference test in female rats. Top: independent of leuprolide treatment, all female rats spent more time with the male stimulus than the female stimulus (saline: n = 13; leuprolide: n = 8). Bottom: similarly, all female rats visited the male stimulus more frequently than the female stimulus, independent of leuprolide treatment. Data are presented as means (± SEM) during the entire 10-min test; n = number of subjects in each group
