To elucidate further pituitary influence on testicular function, we studied the effect of PRL, GH, and LH alone or in various combinations on the maintenance of testicular LH receptor concentration and testosterone synthesis in response to LH (testicular responsiveness) in hypophysectomized adult rats.

Stimulating luteinizing hormone
Drug Testing and Analysis, 2011Low molecular weight luteinizing hormone (LMWLH) receptor agonists could be of interest as a potential doping substance for athletes. These orally active compounds induce the production of endogenous hormones such as testosterone in a similar way to LH.

THERE is a demand for an easy and accurate method of assaying the luteinizing fraction of gonadotrophic hormone. The present method depends upon the formation of corpora haemorrhagica in the ovaries of immature female mice after rendering their Graafian follicles mature.

Stereoisomers of luteinizing hormone-releasing hormone
Biochemical and Biophysical Research Communications, 1974Summary Six decapeptide analogs of the luteinizing hormone-releasing hormone (LH-RH) were prepared with the D-isomers of pyroglutamic acid, histidine, tryptophan, tyrosine, leucine, and arginine successively replacing the corresponding L-amino acids of the hormone. [D-pGlu 1 ]-LH-RH and [D-His 2 ]-LH-RH had appreciable LH-releasing activities, 8% and

A RADIOIMMUNOASSAY FOR AVIAN LUTEINIZING HORMONE
Journal of Endocrinology, 1972SUMMARY A radioimmunoassay for avian luteinizing hormone (LH) is described, using antisera raised against chicken pituitary gonadotrophins of varying degrees of purity, and purified chicken LH for radio-iodination. A postprecipitation double antibody method was developed with a sensitivity to 30–60 pg of purified chicken LH.

Radioimmunoassay of Luteinizing Hormone Releasing Hormone
Nature, 1973THE isolation and characterization of hypothalamic luteinizing hormone releasing hormone (LH–RH) and its subsequent synthesis have made possible the production of an antibody specific for this decapeptide.

LH is a member of the pituitary glycoprotein hormone (GPH) family and consists of a non-covalently linked GPH α-subunit and hormone-specific β-subunit. The GPH α- and LH β-subunits contain a cysteine-knot motif and several N-linked glycosylation sites, both of which are important for biological activity.

The concentrations of 17-oxosteroids in the spermatic venous blood of anaesthetized dogs were used as an index of LH release to assess the effects of arginine-vasotocin on the response of the canine pituitary gland to exogenous luteinizing hormone releasing hormone (LH-RH).

Luteinizing hormone and the aging brain
2021Fluctuations in luteinizing hormone (LH) release contribute to the development and maintenance of the reproductive system and become dysregulated during aging. Of note, increasing evidence supports extra-gonadal roles for LH within the CNS, particularly as it relates to cognition and plasticity in aging and age-related degenerative diseases such as ...
