What's the difference between intromission and intromittent?
Intromission
Definition:
(n.) The act of sending in or of putting in; insertion.
(n.) The act of letting go in; admission.
(n.) An intermeddling with the affairs of another, either on legal grounds or without authority.
Example Sentences:
(1) Local application of 8-OH-DPAT (0-5 micrograms) into the median raphe nucleus, facilitated male rat sexual behavior, as evidenced by a decrease in number of intromissions preceding ejaculation and in time to ejaculation.
(2) The hymen was not penetrated as a result of intromission and therefore the site of ejaculation would have been in the urogenital canal of the 4 primigravid elephants.
(3) On the other hand, the values of the instantaneous frequency, duration, and rhythmicity of the copulatory thrusting movements performed during mounts, intromissions or ejaculations did not differ significantly from the values obtained under saline treatment.
(4) No differences in anxiety were found between the group of animals without sexual activity and the group of animals tested after five intromissions of the first ejaculatory series.
(5) Preliminary investigations indicate that discrete electrolytic lesions to the lateral and posterior parvocellular hypothalamic paraventricular nucleus (PVN) abolished this ejaculation-associated increase in CSF OT, prolonged mount and intromission latencies and reduced the absolute postejaculatory interval (PEI).
(6) MP-AH lesions reduced or completely eliminated the display of manual contacts of the partner, mounts, intromissions and ejaculations without interfering with masturbation.
(7) When the III between short intromissions from a rested male was experimentally increased to 100 s by use of a halter and lead device, the duration of lordosis was significantly less than that displayed by females paired with control males (8-s III) and virtually the same as that displayed by females paired with males that produced only long intromissions.
(8) In normal mating, house mice vary dramatically in the number and duration of intromissions that precede ejaculation.
(9) Impairment of male sexual behavior was indicated by an increase in ejaculation latency, in the number of mounts and a decrease in the number of ejaculations up to 30 min after the first intromission.
(10) Surprisingly, intromissive performance was significantly better in intact breeding males than in castrates given even the highest dosage of TP.
(11) All currently available devices provide a penile shaft rigid enough for intromission, but because all devices occupy only the corpora cavernosa, the erect penis will not be as long or as great in circumference as the patient's physiologic erections once were.
(12) Only two mounts and no intromissions were observed in 6 rats during the test period.
(13) 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.
(14) One should keep in mind that the goal is to have a stallion behave in a disciplined manner, allowing for his expression of libido and effective mounting, intromission, and ejaculation.
(15) Pre- and postnatal nicotine treatment did not affect the overall sexual performance of the male rats, although the number of mounts and intromissions during a second series decreased.
(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.
Intromittent
Definition:
(a.) Throwing, or allowing to pass, into or within.
(a.) Used in copulation; -- said of the external reproductive organs of the males of many animals, and sometimes of those of the females.
Example Sentences:
(1) After PCPA treatment, however, the intromittive and ejaculatory capacity of all experienced animals improved significantly.
(2) A friend in the bird lab conducted a pioneering investigation into the sex lives of mallards (with their now famously cork-screwed penises), a chum in the insect lab down the corridor busied himself with the intromittent organ of the bed bug (think hyperdermic needle) and elsewhere another colleague had just discovered toxic proteins in Drosophila ejaculates that reduce the lifespan of females.
(3) Males implanted SC with Silastic capsules containing ATD displayed significantly less neck gripping, mounting and intromittive behavior than intact males which received empty capsules, although the ATD-induced reductions in behavior were not as large as those seen after castration.
(4) None of the experimental models revealed unequivocal support for detrimental effect of large numbers of intromittive copulations on 'central mechanisms' regulating heat duration.
(5) It rather seemed that frequent intromittive copulations and ejaculates affected the 'peripheral' genital tract (vulva, vagina, cervix) making further copulation of a highly aversive quality so that sexual encounters were avoided or prevented.
