Modulation of Pituitary Gonadotropin Response to Gonadotropin-Releasing Hormone by Estradiol
The Journal of Clinical Endocrinology & Metabolism, 1974ABSTRACT This study was designed to investigate the possibility that estradiol-17β plays a role in the initiation of the surge of gonadotropins at midcycle by increasing pituitary responsiveness to hypothalamic gonadotropin-releasing hormone (GnRH). The effect of estradiol-17β on pituitary response to 50 μ GnRH was studied in 15 women on day 2 of the ...

The incorporation of labeled amino acids and glucosamine into LH and FSH by cultured rat anterior pituitary cells and anterior pituitary homogenates is reported. There was a significant augmentation in this incorporation by cells after 6 days of culture in the presence of GnRH.

Gonadotropin-releasing hormone (GnRH) agonists are widely used in hormone therapy for prostate cancer. We report a patient with pituitary apoplexy following this therapy as a rare complication and review the related literature. A 62-year-old man presented with elevated prostate specific antigen.

The Preparation and Properties of Equine Pituitary Gonadotropin
Journal of the American Pharmaceutical Association (Scientific ed.), 1950A method is described for the alkaline extraction of equine pituitary glands which produced gonadotropic hormone, containing only traces of foreign protein but which was contaminated with posterior pituitary extract. Equine pituitary gonadotropin was found to possess a lower potency than that of serum gonadotropin.

Familial Monotropic Pituitary Gonadotropin Insufficiency
The Journal of Clinical Endocrinology & Metabolism, 1968Abstract Three siblings, 2 females and 1 male, had eunuchoidism with selective insufficiency of pituitary gonadotropin. A fourth sibling, a male, probably was affected, but death precluded definitive study. A maternal half sister was normal. There were no distinctive somatic features except absence of secondary sex characteristics and relatively long ...

Pituitary Gonadotropins and Multiple Births in Nigeria
Acta geneticae medicae et gemellologiae, 1972Radioimmunoassay of FSH and LH serum levels has been carried out on 15 Nigerian women, 6 of them mothers of singletons and 9 mothers of twins (2 of two sets). Higher FSH levels have been found in mothers of twins, which supports the view that a higher production of pituitary gonadotropins, resulting in a higher incidence of multiple ovulation, may be ...

Comparative biochemistry of pituitary gonadotropins
General and Comparative Endocrinology, 1969Abstract Except for some limited reports by Fontaine and Gerard and by Clemens et al. on the partial purification of gonadotropic or gonadal hydration factors present in the pituitary of the carp Cyprinus carpio , almost all experiments designed to purify and characterize pituitary gonadotropins have been carried out utilizing pituitaries from ...

Gonadotropin secreting pituitary microadenoma.
Le Journal medical libanais. The Lebanese medical journal, 1993FSH and LH secreting pituitary adenomas may not be as rare as has been previously thought. Women in their reproductive years with a normal estrogenic state and hypergonadotropic amenorrhea should be suspected to harbor a pituitary microadenoma secreting gonadotropins. A computerized tomogram of the pituitary confirms the diagnosis.
