  • Values represent mean (SEM). Mount - I, Frequency of mounts (defined as direct genital contact by the male onto flanks of the female without achieving penetration, often accompanied by female lordosis) without intromission; Mount + I, frequency mounts with intromission (defined as two or more distinct thrusts with penetration); Ejac., ejaculation frequency; 1st Mount, latency to first mount (with or without intromission); III, average inter-intromission interval; ID, average intromission duration; M/I, ratio of mounts to intromissions; Crossings, number of entries/exits into the male side; Male side, total time spent on male side; Return, average latency to return to the male side following intromission; CARR, carrageenan; ZYM, zymosan.
