The effects of decreasing the frequency of pulsatile gonadotropin-releasing hormone
(GnRH) stimulation on pituitary responsiveness were studied in (a) men with isolated GnRH …

The effects of increasing the frequency of pulsatile GnRH administration on LH and FSH
responsiveness were studied in five GnRH-deficient men who had achieved normal sex …

The pattern of the gonadotropin-releasing hormone (GnRH) stimulus is critically important in
the regulation of pituitary gonadotropin secretion and continuous infusions down-regulate …

In adult ovariectomized rhesus monkeys bearing hypothalamic lesions which reduced
circulating LH and FSH to undetectable levels, sustained elevated gonadotropin …

Regulation of LH release by GnRH was studied in superfused anterior pituitary cells from 30-
day-old female rats or hamsters. Dispersed cells were cultured 4-6 days on Cytodex beads …

The feedback effects of testosterone (T) and estradiol (E2) on FSH and LH secretion were
compared in dispersed pituitary cells from adult male rats perifused with pulses of GnRH …

Gonadotropin-releasing hormone (GnRH) releases both follicle-stimulating hormone (FSH)
and luteinizing hormone (LH) from the anterior pituitary, but not always at the same time …

Previous reports have demonstrated that long-term continuous administration of
gonadotropin-releasing hormone (GnRH) to pituitary cells results in a decreased level of …

Gonadotropin-releasing hormone (GnRH) induces both synthesis and release of pituitary
gonadotropins, but rapid or slow frequencies of stimulation result in reduced LH and FSH …

Patients who have severe hypogonadotropic hypogonadism caused by presumed
hypothalamic disease often have a subnormal LH response to a bolus dose of …
