The effect of continuous, short-term (6, 12 and 24 h), s.c. administration of 50 nmol·day−1 kisspeptin-54 on the HPG axis. The effect of continuous, short-term (6, 12 and 24 h), s.c. administration of 50 nmol·day−1 kisspeptin-54 in adult male Wistar rats on plasma levels of (A) LH, (B) FSH and (C) free testosterone. All data are expressed as mean ± SEM. Significance is indicated by *P < 0.05, **P < 0.01, ***P < 0.001 vs. saline-treated control, or a kisspeptin-54-treated group at a different time point (n = 5 per group). FSH, follicle-stimulating hormone; HPG, hypothalamic-pituitary gonadal; LH, luteinising hormone.
