  • †F tests are from one-way, repeated measures ANOVAs comparing data from baseline, timed, and triggered tests; Hunyh-Feldt correction was applied where appropriate; n = 7 for each test.

  • * Tests lasted until an ejaculation was achieved or until 20 min had elapsed; the first 2.5 min was allowed for habituation during which no data were collected.

  • aDefined as (total investigation time/test duration) × 100.

  • bDefined as (investigation time while laser ON/laser ON duration) × 100.

  • cDefined as (investigation time while laser OFF/laser OFF duration) × 100.
