Progesterone is able to bring about an LH and FSH surge in the estrogen-primed
ovariectomized rat while dexamethasone brings about selective FSH release. The purpose …

In a previous study we demonstrated that in the ovariectomized estrogen-primed immature
rat, progesterone induced a gonadotropin surge while the gonadotropin mRNA subunit …

In order to investigate the mechanism underlying ovarian steroid action on gene expression
of hypothalamic luteinizing hormone releasing hormone (LHRH), changes in LHRH mRNA …

We have recently demonstrated that the rat ovary expresses LHβ, FSHβ, and the common
alpha subunit mRNA. In the present report, we studied the regulation of LHβ and of …

Rat ovaries stimulated with human follicle-stimulating hormone (hFSH) overexpress a factor
that attenuates the LH surge in the rat: the putative gonadotropin surge-attenuating factor …

The rostro-caudal distribution of luteinizing hormone-releasing hormone (LHRH) in the
hypothalamus of neonatally estrogenized (10 μg EB for 1–5 days), sterile female rats was …

During the infantile period of the female rat (8–21 postnatal days [PND] of age), there is a
dramatic increase in plasma FSH, which is thought to be important in initiating ovarian …

FSH-beta mRNA is dramatically regulated in the infantile female rat anterior pituitary.
Elevated plasma levels of FSH correspond with increased FSH-beta mRNA levels which …

Pro-oestrous-type LH surges were induced by treating ovariectomized rats (day 0) with
either oestradiol benzoate (OeB, 40 μg/rat) or oestrogen (10 μg/rat followed by progesterone …

Hyperstimulation of ovarian function with human FSH (hFSH) attenuates the preovulatory
surge of LH. These experiments aimed at investigating the mechanism of ovarian-mediated …
