Behavior during the Coolidge effect experiment

Measure of sexual behavior	Female 1	Female 2
Mount latency	31.2 ± 10.3 sec	54.4 ± 30.3 sec
Intromission latency	31.2 ± 10.3 sec	156.4 ± 75.6 sec
Ejaculation latency	534.4 ± 111.4 sec	512.0 ± 195.9 sec, (n = 2)
Postejaculatory interval	414.8 ± 51.8 sec	850.0 ± 53.0 sec, (n = 2)
Number of mounts (1st hr)	16.0 ± 2.1	11.4 ± 4.5
Number of intromissions (1st hr)	37.0 ± 3.3	11.2 ± 4.5^*
Number of ejaculations (1st hr)	4.2 ± 0.5	0.6 ± 0.4^1-160
Interaction with female 1:
Number of ejaculations (total)	7.8 ± 0.5 (range, 6–11)
Time to sexual satiety	144.0 ± 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.
