When animals were tested in a novel spatial maze, the traverse times were similar (P = 0.564) for GnRH-Rec and Control animals. Comparison of individuals’ performances in the long-term spatial memory and novel maze assessments, indicated that all animals took significantly (Familiarity P < 0.001) longer to complete the novel maze, irrespective of treatment group (Treatment × Familiarity P = 0.146). The increase in traverse time was significantly affected by treatment (P = 0.008), whereby Control animals took 1.6-fold longer, and GnRH-Rec animals only took 1.1-fold longer, to complete the novel maze compared to the long-term memory assessment.
