 Number of ejaculations (total)  7.8  ± 0.5 (range, 6–11)
 Time to sexual satiety144.0  ± 14.7 min (range, 105–195)
 Number of presentations  2.0  ± 0.5 (range, 1–4)
  • Values are presented as means ± S.E.M. (n = 5, except where indicated). The mount latency, intromission latency, ejaculation latency, and postejaculatory interval are derived from the first copulatory bout with each female.
