Abstract

Male rats were ranked in dominance orders, were allowed to copulate to exhaustion and then were tested for sexual rearousal in five different treatment conditions. Novel females rearoused 60 per cent of the males to ejaculation. Five-minute encounters with dominant or subordinate males stimulated 33 per cent to ejaculation with a familiar female. Fifteen per cent ejaculated with the familiar female after a 5 min rest and 15 per cent after an encounter with an unknown male. The degree of rearousal was not related to fighting or to mounting during male-male encounters, nor did the dominant males show a higher degree of sexual potency.

    Additionally, laboratories use different criteria to determine when to end paced mating tests. Tests may end after a set period of time,23,24,27,30,31 after the receipt of a certain number of stimulations,23,24,27,30,31 or after the receipt of an ejaculation (ie, the entire test comprises a single ejaculatory series).32–34 The current study was designed to clarify the influence of procedural choices on the display of paced mating behavior and, consequently, the conclusions that can be drawn about the neurobiological mechanisms necessary for female sexual behavior.

  • Sexual selection in socially-structured, polyandrous populations: Some insights from the fowl

    2019, Advances in the Study of Behavior
    Citation Excerpt :

    Female sexual novelty. Male fowl display a typical coolidge response, i.e. a decline in a male's sexual interest in a female over successive mating with this female, replaced by a sudden renewal in sexual interest upon exposure to a sexually novel female (Brown, 1974). Importantly, this response is recapitulated in patterns of sperm allocation, as males preferentially invest sperm in matings with sexually novel females and reduce their investment with increasing sexual familiarity (i.e. over successive mating) with a female (Pizzari et al., 2003).

  • Hormones and the Coolidge effect

    2018, Molecular and Cellular Endocrinology
    Citation Excerpt :

    One consistent phenomenon, related to sexual behavior, is the resumption of mating induced by a novel sexual partner (Bermant et al., 1968; Dewsbury, 1981; Lucio et al., 2014). Although largely reported in males (Wilson et al., 1963; Bermant et al., 1968; Brown, 1974; Rodriguez-Manzo, 1999; Lucio et al., 2014, 2017), the study of the Coolidge effect in females is a relatively new area and a growing field of research (Lisk and Baron, 1982; Ventura-Aquino et al., 2016). The term Coolidge effect was coined by a research group, led by the behavioral endocrinologist Frank A. Beach, derived from an anecdotal event, which veracity has not been confirmed (Wilson et al., 1963; Ågmo, 2007).

    2016, Sexual Medicine Reviews
    Citation Excerpt :

    However, this may be due to the “Coolidge effect,” a rearousal phenomenon where the refractory period is reduced in the presence of a new sex partner.85–87 Evidence of the Coolidge effect is best documented in animal studies.87 Access to a new or novel sexual partners may promote sexual desire and motivation to orgasm, truncating the refractory period.
