2016, Hormones and BehaviorCitation Excerpt :Our understanding of the molecular and neural pathways through which pup exposure comes to alter maternal behavior requires consideration of the pathways through which hormones influence maternal behavior. The pattern of pregnancy hormone stimulation that primes the rodent maternal brain begins at mating when cervical stimulation initiates a twice-daily pattern of prolactin release from the anterior pituitary (for approximately 9–10 days after mating) that functions to prevent degradation of the corpora lutea (Terkel and Sawyer, 1978). Consequently, there is a steady increase in progesterone (P) during the first part of pregnancy, which prepares the uterine endometrium for implantation and maintains a uterine environment that promotes growth of the embryo (Csapo and Resch, 1979a,b; Zakar and Hertelendy, 2007).
Orphanin FQ-ORL-1 Regulation of Reproduction and Reproductive Behavior in the Female
2015, Vitamins and HormonesCitation Excerpt :Her copulatory rate is lower than the rate the male would set if he were allowed to set the pace (Adler, 1969, 1978; Erskine, Kornberg, & Cherry, 1989; McClintock, 1984; Mendelson & Gorzalka, 1987; Pfaus, Smith, & Coopersmith, 1999; Yang & Clemens, 1997). This female-induced pacing of the copulatory rate increases sperm transport into the uterus and induces a neuroendocrine reflex that elicits a progestational state increasing the likelihood of pregnancy (Chester & Zucker, 1970; Erskine, 1987; Kornberg & Erskine, 1994; Matthews & Adler, 1977; McClintock, Toner, Adler, & Anisko, 1882; Terkel & Sawyer, 1978). Estradiol-only priming that induces maximal sexual receptivity produces very low levels of proceptivity, whereas maximal levels of proceptivity and receptivity are produced by estradiol and progesterone exposure as seen during the estrous cycle (Edwards & Pfeifle, 1983; Hardy & Debold, 1971; Hlinak & Madlafousek, 1981; Tennent, Smith, & Davidson, 1980; Whalen, 1974).
Clitoral anesthesia disrupts paced copulation in the female rat
2014, Physiology and BehaviorCitation Excerpt :In natural and laboratory environments female rats control the rate of copulatory stimulation they receive from males by means of approach and avoidance behaviors, collectively known as “pacing” [1–3]. Pacing behavior increases the likelihood that mating stimulation will initiate luteal function thus enhancing the probability of pregnancy when the female is paired with a fertile male or pseudopregnancy if the male in infertile [4–18]. The ability of females to pace or control the initiation and rate of sexual stimulation also leads to a positive reward state that induces both conditioned place and partner preferences [9–13].
