Influence of chronic (14 days) administration of S32212 compared with paroxetine on sexual behavior and body weight in male rats

Data are means ± S.E.M. (n = 12 per value). Number of ejaculations and latency to the first ejaculation were recorded in 30-min sessions performed at days 0, 7, 14, and day 21. Drugs or vehicle were administered daily from day 0 (acute treatment) to day 14 (chronic treatment). ANOVA results were as follows: For ejaculations, day 0, F2,33 = 0.5, P > 0.05; day 7, F2,33 = 36.1, P < 0.001; day 14, F2,33 = 8.2, P < 0.01; and day 21, F3,23 = 1.2, P > 0.05. For latency, day 0, F2,33 = 0.3, P > 0.05; day 7, F2,33 = 9.6, P < 0.001; day 14, F2,33 = 6.5, P < 0.01; and day 21, F2,33 = 1.9, P > 0.05. For body weight, day 0, F2,33 = 0.7, P > 0.05; day 7, F2,33 = 0.5, P > 0.05; day 14, F2,33 = 4.0, P < 0.05; and day 21, F2,33 = 5.2, P < 0.05.
