(16) The probability of autogrooming was higher, and the duration longer, after mounts that ended mount bouts and after intromissions, than after mounts that were incorporated within a mount bout.
(17) Prior to any drug treatment, middle-aged males (13 months of age) exhibited prolonged latencies to ejaculation and intervals between intromissions when compared to young male rats (3 months of age).
(18) In males with intact noradrenaline, 5-MeODMT facilitated sexual behavior by reducing the number of intromissions required for ejaculation; inhibitory actions were also noted, since 5-MeODMT prolonged intromission and ejaculation latencies.
(19) Sexual activity of each mouse (number of ejaculations and intromissions) was estimated under competitive conditions between the ages of 120 and 150 days in eleven repetitions.
(20) Numbers of mounts, intromissions, ejaculations, postejaculatory songs, and the intromission and ejaculatory patterns were like those of control rats, although the decorticate rats had fewer mount bouts and showed abnormalities in the execution of movements.
Intromit
Definition:
(v. t.) To send in or put in; to insert or introduce.
(v. t.) To allow to pass in; to admit.
(v. i.) To intermeddle with the effects or goods of another.
Example Sentences:
(1) Clonidine-evoked dose-dependent decrements in the number of males mounting, intromitting and ejaculating, with administration into the medial preoptic area more effective than into the 3rd ventricle.
(2) In contrast, among the castrates with testosterone clamped at low but stable levels, the proportion of males that mounted, intromitted, or ejaculated was not affected by photoperiod.
(3) The lowest dose of apomorphine (0.2 microgram) infused into the ventricle reduced the number of ejaculations, slowed the rate of intromitting and decreased the percentage of mounts on which the male gained vaginal intromission.
(4) In tests with stimulus females, significantly fewer E-treated castrates displayed, neck-gripped, and intromitted than did intact males.
(5) Instead, estradiol treatment tended to interfere with the capacity to intromit.
(6) The highest dose selectively abolished mounting, intromitting and ejaculating in sexually experienced male rats paired with an oestrous female.
(7) A significantly higher proportion of males receiving 21 or 24 hr of daily T exposure mounted, intromitted and ejaculated compared to groups with daily T exposures of 18 hr or less.
(8) The facilitation and inhibition of infanticide as a function of time after mating is mediated by the act of ejaculating rather than by mounting and intromitting during mating or by cohabiting with a female either before or after mating.
(9) However, intromission latencies increased and 7 out of 10 males failed to intromit during some post-lidocaine tests.
(10) Four of the five individuals in the group given R1881 showed occasional mounts with thrusts, three showed sporadic erections and one sheep intromitted in the final test.
(11) In Experiment 3 scopolamine, injected alone into the preoptic area, again decreased the percentages of animals mounting, intromitting, and ejaculating.
(12) Allowing the male to mount (but not intromit) a female whose vagina had been taped partially counteracted the behavioural effect of beta-endorphin.
(13) However, the female mating pattern was significantly altered in that although females in both lesion groups initially allowed a stud male to mount, they usually did not allow the male to intromit.
(14) Prolactin-injected animals had significantly reduced intromission rates (P less than 0.01) and significantly increased latencies to mount (P less than 0.05) and to intromit (P less than 0.01) when compared to vehicle-injected controls.
(15) Thus, one-half of the treated rats failed to intromit and ejaculate, and those displaying the behaviors exhibited elongated intercopulatory and postejaculatory intervals.
(16) Most rats treated with higher doses of NPY (0.02, 0.12, or 0.47 nM) mounted and intromitted only a few times before the cessation of sexual activity, and elongated latencies to the initial mount and intromission were observed.
(17) Prenatal nicotine decreases male sexual behavior as measured by the number of males that mounted, intromitted or ejaculated.
(18) In the first mating test, SOC-X rats mounted and intromitted more than ISO-X, but not SOC-S, rats.
(19) From these results, it was concluded that methamphetamine inhibits the intromitting and ejaculating behavior in male rats.
(20) Although males mounted these females, they usually failed to copulate, possibly because the females did not perform certain postural adjustments which assist males to intromit.
