DEHP exposure of 5 and 50 [micro]g/kg/d also increased the latency to the first intromission, whereas the mating duration and parameters of sexual performance (frequency of mounts with intromissions and thrusts, intromission ratio, genital grooming) remained unchanged.
5 [+ or -] 2 ([dagger]) nM = Number of Mounts Until the First Ejaculation; nI = Number of Intromissions Until the First Ejaculation; PEI = Post Ejaculatory Interval; NM+NI+NE = Sum of the Total Number of Mount, Intromission and Ejaculation in 40 min; SAI = Sexual Activity Index; CE=Copulatory Efficiency.
The sexual behavior of the male rats was studied as explained elsewhere, (26) the copulatory behavior of the male rat was characterized by a series of mounts with or without vaginal intromission from the rear of the female approximately once in every 30 to 120 sec, that eventually culminates in ejaculation.
Mounting behavior: Mount frequency (MF) was determined by counting the number of pre-ejaculatory mounts with and without intromission in given period of observation.
In contrast, to that numbers of intromissions were decreased.
The right to one's own image is protected against illegal intromissions.
As this occurs, the male's penis becomes erect and he attempts intromission.
This shift is pointed out by a deictic dissonance, without any intromission by the narrator.
Mount, intromission and ejaculation latencies and post-ejaculatory interval were recorded.
Nil responses (data not shown) were observed for the number of attempted mounts, intromission latency, ejaculation latency, intromission frequency, ejaculation frequency, postejaculatory interval, number of thrusts per intromission, and grooming frequency, as previously described (Mani et al.
Only occurred after copulation ended; male left without attempting further intromissions.
Changes in male mating behavior included shortening of latency to intromission and increased intromissions.
