Conditioned place preference (CPP) to vaginal secretions (VS) in hormone-manipulated adult hamsters. Corrected changes in preference and difference scores are shown, mean ± SE. * Indicates difference from no change (zero), P < .05. Long-term gonadectomy with blank hormone capsules prevented the CPP for VS observed in the gonadectomized (GDX) + testosterone group.
