Chapter 4: Neuroendocrinology of Sexual Behavior in the Male. In the last chapter, we looked at the role of primarily estrogen and progesterone in stimulating proceptive and receptive aspects of female sex behavior. In our consideration of male sex behavior, we will consider how the primary androgen, testosterone, is secreted by the testes.

Sexual behavior in males and females has three components: attraction, motivation and performance. In most species, either the male or the female has evolved elaborate displays to attract the opposite sex. Without motivation, the desire to seek out sex is low.

The copulatory act itself is the process of DNA exchange. All of these aspects of. Sexual behaviour encompasses a variety of sensory stimuli that makes sex rewarding in both humans and rats alike.

Stress was attained by immobilization inside plastic tubes for 6 h a day during the light period, starting at a.m., for 15 days (early pubertal animals used for analysis of sexual behavior) or for 60 days (sexually mature rats used in fertility experiments) (see Ref.

9, for the phases of male rat sexual development). Sexual behaviour in the male rat Sexual behaviour in male rats consists of three behaviours: Mount: the animal assumes the copulatory position on top of the female and grasps her flanks, but does not not insert his penis into the female's vagina; Intromission: the male mounts the female and briefly ( milliseconds) inserts his penis.

The peak rate was characteristically distinctive for abortive mounts, intromissions, and ejaculations, as was the temporal pattern.

Author(s): Barfield, RJ; Geyer, LA | Abstract: During the refractory period that follows ejaculation, the male rat regularly emits kilohertz vocalizations. These cease after about three-fourths of the total period has elapsed, and this corresponds to an "absolute refractory period" during which the male cannot spontaneously initiate copulation.

Similar kilohertz vocalizations occur in Cited by: Early reports examining male sexual behavior note that the number of intromissions per ejaculation for outbred male rats would be closer to our bLR males than bHR males (Erskine, ), indicating that it is the bHR group demonstrating perturbed intromission timing.

bHR males exhibit more intromissions at a faster rate than by: Male rat sexual behavior has been intensively studied over the past years, but few studies have examined how sexual behavior changes over the course of several days of interactions. o Sexual receptivity, often corresponding with ovulation in female mammals, is necessary for _____ copulation o In the brain of the male rat, the region especially important for.
