“…This conclusion is in complete agreement and further strengthened by the findings of Imamichi (1964), Astrada, et al (1969), and Aron et al (1969), all of whom worked with adult rats. In addition, Greenwald (1970) has found that FSH by itseif will induce ovulation in phenobarbitone-blocked hamsters.…”

SynopsisAdult proestrus rats were prevented from ovulating by injection of chlorpromazine (CPZ) between 11: 30 AM and 11: 45 AM. At 3: 00 PM on the same day CPZ-blocked females were injected intravenously with follicle stimulating hormone (NIHFSH-S5) and/or luteinizing hormone (NIHLH-B6). Data from these studies demonstrate a synergistic action between FSH and LH resulting in ovulation. Evidence for synergism was based on the observation that the incidence of ovulation produced by various combinations of the gonadotropins was in general greater than when either one was administered alone.

“…Although this is a well-known phenomenon in the rabbit and cat, it does occur in the spontaneously ovulating rat as well. In the intact female, mating facilitates LH release (Moss et al, 1977) and if spontaneous ovulation is blocked or if sexual receptivity is induced before the time of the normal ovulatory surge of gonadotropin, copulation can induce ovulation in this species (Aron et al, 1966;Everett, 1967;Zarrow and Clark, 1968). The data shown in Fig.…”

Mating has been shown to have effects on ovulation in a number of species which ovulate spontaneously, such as rats (Aron, Asch & Asch, 1961; Aron, Asch & Ross, 1966; Zarrow & Clark, 1968) and sheep (Parsons, Hunter & Rayner, 1967; Van der Westhuysen, Van Niekerk & Hunter, 1970). In the sow, the results obtained by Pitkjanen (1955) and Lebedev (1957) Fifty-nine Large White gilts were mated at the time of the second oestrus following withdrawal of methallibure (I.C.I.), which had been given for 21 days (100 mg/day in the feed) in order to control ovulation and to facilitate detection of the time of ovulation. The gilts were mated at the first sign of oestrus, and again 6 hr later, by boars of known fertility. They were then randomly assigned to one of four experimental groups in which coelioscopy took place 30, 35, 40 and 45 hr, respectively, after the onset of oestrus.The time ofovulation in this group (A) was compared with that in a group of thirty-seven unmated gilts (B) given a single injection of pmsg 24 hr after the last treatment with methallibure, and in a second control group (C) of seventy-four unmated gilts on their second oestrus following withdrawal of methallibure.
