Changes in male mating behavior included shortening of latency to intromission and increased intromissions.
Treatment of established breeder males with the LTX-diol drinking solution for 1-4 weeks had no significant effect on mounting, intromission, ejaculation, ejaculation latency, or grooming behavior (data not shown).
Paced mating test was terminated: (1) if the female returned to the stimulus male rat, following the 10th intromission; (2) if the female received no intromission within the first 15 min from the beginning of the test; (3) when the interval between two intromissions was longer than 30 min.
Similarly, males housed on ground corncob bedding also displayed substantial reductions (Figure 4B) in mounting behavior (> 98%), intromission (> 97%), ejaculation (> 98%), ejaculation latency (> 79%), and grooming frequency (~75%) when placed with breeder females, which could be linked to the hypothalamic-pituitary-testicular axis.
mount frequency (MF), the number of intromissions, i.
The orally administered extract had a dose dependent positive effect on mounting frequency, intromission frequency and ejaculation frequency and the most significant effects (p<0.
Using these measures, the following parameters were computed % mounted, % intromitted, % ejaculated, copulatory efficiency (number intromissions / number of mounts + number intromission) and inter copulatory interval.
2 of the SC (12), determining the legal channel for defence against the illegitimate interferences or intromissions that may affect these rights, as well as determining the injured party's rights in the event of these intromissions (including the right to compensation for the damages suffered, which must always be set in accordance with the provisions of this OL).
The fact that four of the second males' copulatory behavior was similar to the first males' (having two intromissions totaling > 30 min), suggests that copulatory plugs are not ubiquitous, or at least not completely effective.
Behaviorally, intromissions were distinguished from mounts without intromissions by the occurrence of deep thrust followed by rapid, springing dismount.
Mount frequency (MF) as the number of mounts preceding ejaculation and intromission frequency (IF) as the number of intromissions preceding ejaculation were also recorded.
