Effects of peripheral kisspeptin administration (intravenous 1 nmol/kg/hour) on circulating reproductive hormone levels in humans. Kisspeptin administration increased circulating levels of (A) kisspeptin (****P < .0001) and (B) luteinizing hormone (LH, ****P < .0001), compared with placebo. (B) Kisspeptin administration had no effect on follicle stimulating hormone (FSH) or (C) testosterone levels. Data shown as mean ± SEM, ****P < .0001, mixed-model analysis of variance, n = 26 healthy men.
