Mean urinary progesterone metabolite (pregnanediol glucuronide [PdG]) concentration before and after GnRHa treatment in aging female macaques. A single dose (0.25 mg/kg of body weight) of GnRHa (leuprolide acetate) was administered intramuscularly. Friedman repeated-measures analysis of variance on ranks was conducted for comparison. Levels not linked by the same letter indicate a statistically significant difference (P<0.05). CR, creatinine; GnRHa, gonadotropin-releasing hormone agonist.
