Data are shown as mean ± SEM. Statistical comparisons were done with ANOVA for repeated measurements. Abbreviations: BioTe: bioavailable testosterone, X-ApEn: cross approximate entropy. Contrasts: aKTCZ vs control, P = 0.025; bcontrol vs KTCZ, P < 0.0001; cganirelix vs KTCZ, P = 0.004; dControl and ganirelix vs KTCZ, P < 0.0001; eganirelix vs KTCZ, P = 0.012, fcontrol vs ganirelix, P = 0.004.
