Effects of different doses of MA on (A) proceptive behavior and (B, C) the lordosis response. Adult ovariectomized Sprague-Dawley rats were primed with EB 48 h (5µg) and 24 (10µg) prior to the day of behavioral testing. Four hours before the start of behavioral testing, animals received an injection of 200µg P. MA (either 1, 3, or 5 mg/kg/day) or saline vehicle was co-administered on each day of the hormonal priming. A one-way ANOVA followed by a Newman-Keuls comparison indicated a significant effect of the dose of MA administered. Treatment with 5mg/kg/day of MA increased the number of proceptive events that occurred within 10 min, the LQ and LS, compared to the saline-treated controls (*p<0.05) Data are represented as means ± SEM. (n = 7 animals in each group).
