This study was conducted to test the hypothesis that the rate (dose/time) at which oestradiol-17 beta (oestradiol) is presented to the hypothalamo-pituitary axis influences secretion of LH, FSH and prolactin. A computer-controlled infusion system was used to produce linearly increasing serum concentrations of oestradiol in ovariectomized ewes over a period of 60 h. Serum samples were collected from ewes every 2 h from 8 h before to 92 h after start of infusion, and assayed for oestradiol, LH… Expand
Oestradiol and the surge release of gonadotrophins in the ewe
Abstract This experiment was designed to study the effects of different doses and different patterns of change in circulating concentrations of oestradiol on the genesis of the surge release ofExpand
Effect of intracerebroventricular infusion of genistein on prolactin and LH secretion in ovariectomized ewes during short days
TLDR
It is demonstrated that genistein may affect the hypothalamo-pituitary neuroendocrine axes activity in long-term OVX ewes, under the conditions of short days. Expand
Melatonin Modulation of the Daily Prolactin Secretion in Intact and Ovariectomized Ewes
TLDR
It is suggested that melatonin may affect the daily secretion of prolactin in ewes during the breeding season, and that the variable response of Prolactin to the melatonin signal in intact and ovariectomized ewers relates to the interaction between both ovarian steroids – estradiol and progesterone – and the prolactIn-releasing factor. Expand
Luteinizing hormone and growth hormone secretion in ewes infused intracerebroventricularly with neuropeptide Y.
TLDR
NPY exerts a persistent inhibitory effect on secretion of LH, and may stimulate the secretion of GH during the initiation and cessation of infusion of NPY, which support a role for NPY in mediating the effects of undernutrition on both LH and GH, and also provides evidence for potential mechanisms by which leptin, acting throughNPY, may stimulateThe secretion ofGH.

Oestrogen-like effect of genistein on follicle - stimulating hormone release in ovariectomized ewes *
TLDR
The presented results demonstrated that genistein could affect the FSH release in the OVX ewes, and the number of immunoreactive FSH cells in the adenohypophysis and IR material stored in these cells increased ingenistein-infused animals. Expand
Lack of effects of indomethacin on estradiol feedback control of luteinizing hormone in ovariectomized ewes.
We tested the hypothesis that indomethacin, a potent inhibitor of prostaglandin synthesis, would modify estradiol's effects on tonic and surge concentrations of LH in chronically ovariectomized ewesExpand
Effect of 17beta-estradiol on the preovulatory surge of LH in the bovine female.
TLDR
Increased levels of E(2) greater than luteal phase concentrations are needed to initiate preovulatory surges of LH, and it appears that concentrations of E (2) need to reach a certain level but do not need to decrease after this initial rise to stimulate a surge release of LH. Expand
Plasma prolactin changes in anoestrous ewes after infusion of genistein into the third ventricle
Genistein, one of isoflavones, is structurally similar to mammalian endogenous oestrogens, which inhibit activity of tyrosine kinase, DNA topoisomerases, and possess antioxidant activity andExpand
Roles of the dominant follicle and the pattern of oestradiol in induction of preovulatory surges of LH and FSH in prepubertal heifers by pulsatile low doses of LH.
TLDR
Prepubertal crossbred beef heifers were injected with 50 micrograms bovine LH every 2 h for 48 h and unilateral removal of either the ovary bearing the largest follicle or the opposite ovary was performed to assess concentrations of gonadotrophins and oestradiol. Expand
Pineal and Melatonin
The aim of this study was to investigate whether melatonin might modulate the daily prolactin secretion in the ewe during a period of ovarian activity and, if so, whether this modulatory action ofExpand

Role of estradiol in inducing an ovulatory-like surge of luteinizing hormone in sheep.
Two experiments were performed to examine the effect of estradiol on secretion of luteinizing hormone (LH) and on the number of receptors for gonadotropin-releasing hormone (GnRH) after downExpand
Luteinizing hormone, follicle stimulating hormone and prolactin secretion in ewes and wethers after zeranol or estradiol injection.
TLDR
Comparisons in the effects of zeranol and estradiol on anterior pituitary hormone secretion within groups of animals of the same sex or reproductive state indicate differences in secretion and plasma concentrations are maintained and expressed even when animals are challenged with structurally different compounds of varying estrogenic potencies. Expand
Ewe luteal function influenced by pulsatile administration of synthetic LHRH/FSHRH.
TLDR
It is suggested that pulsatile administration of synthetic LHRH is able to elevate serum LH levels to an extent sufficient to counteract both natural luteolysis and premature luteal regression induced by E2 treatment. Expand
Long-term negative feedback effects of oestrogen and progesterone on the pituitary gland of the long-term ovariectomized ewe.
TLDR
Plasma concentrations of FSH were reduced by approximately 50% by the oestradiol treatments with no additional effects of progesterone and there was no effect of steroidal treatment on pituitary content of LH or pituitsary levels of GnRH receptors. Expand
Effects of continuous infusions of 4-hydroxyoestradiol and oestradiol on plasma LH-levels in the ovariectomized ewe.
TLDR
4-OHE2 had to be infused at 4-5 times higher rates than E2 to obtain comparable plasma concentrations of either oestrogen and under this condition the effects of E2 were similar indicating that 4- OHE2 has the same potency as E2 at central target sites. Expand
Direct effects of estradiol-17 beta on the number of gonadotropin-releasing hormone receptors in the ovine pituitary.
TLDR
The results suggest that although GnRH is necessary for secretion of gonadotropin-releasing hormone, E2 alone can directly increase the number of GnRH receptors in the pituitary. Expand
Roles of pattern of secretion of luteinizing hormone and the ovary in attainment of puberty in ewes lambs
TLDR
How patterns of luteinizing hormone (LH) change as lambs approach first estrus, whether mimicry of these changes by exogenous LH will initiate events of the pubertal process and aspects of possible roles of the ovary and estradiol in the initiation of an ovulatory surge of LH in prepubertal lambs are examined. Expand
Effects of dopamine and serotonin on concentrations of luteinizing hormone and estradiol-17 beta in plasma of cycling ewes.
TLDR
Neither DA nor 5-HT influenced the decrease in plasma concentrations of progesterone following PGF2 alpha, nor did they influence the onset of the preovulatory surge of LH, and magnitude and duration of the surge were not altered by infusion of either DA or 5- HT. Expand
Preovulatory gonadotropin surge system of prepubertal female sheep is exquisitely sensitive to the stimulatory feedback action of estradiol.
TLDR
The similarity of the dose-response curve for estradiol-induced LH release in the lamb to that which was reported for the mature female indicates that the lamb is equally sensitive toEstradiol stimulatory feedback action long before the age of first ovulation. Expand
GnRH-receptor interaction. VI. Effect of progesterone and estradiol on hypophyseal receptors for GnRH, and serum and hypophyseal concentrations of gonadotropins in ovariectomized ewes.
TLDR
Data indicate that estradiol can increase the number of receptors for GnRH, while the quantity of LH and FSH released into the circulation or contained in the pituitary decreases, suggesting an influence at higher neural centers. Expand
