ML: mount latency; MF: mount frequency; IL: intromission latency; IF: intromission frequency; EL: ejaculation latency; EF: ejaculation frequency. Latencies are expressed in minutes (min), and frequencies are expressed as number of events. Data are expressed as the mean ± SEM; N=10; P < 0.05, P < 0.01, and P < 0.001 response significantly different compared with aged control group; ^##P < 0.01 response significantly different compared with young control group.
