Leuprolide exposure during the periadolescent period increased interest in the male stimulus but decreased interest in the female stimulus during the partner-preference tests in male rats. Top: leuprolide-treated male rats spent more time with the male stimulus than the saline controls (saline: n = 8; leuprolide: n = 8) on Test 1. Bottom: leuprolide-treated male rats spent less time with the female stimulus than the saline controls collapsed across tests. However, post hoc tests indicate that there was only a significant difference between groups on Test 1. Note: the axis range of the two graphs is not the same. Data are presented as means (± SEM) during the entire 10-min test; n = number of subjects in each group. An asterisk (*) indicates significant post hoc difference between groups
