Luteinizing Hormone Estimation
Endocrine Research, 2004Luteinizing hormone (LH) is an important hormone of the reproductive system, which has found application in diagnosis and therapeutic medicine. It plays a vital role in the development and functioning of the reproductive system. Determination of LH concentration is important for detection of dysfunction of the pituitary-ovarian axis, diagnosis of ...

STEROID PRIMING OF THE LUTEINIZING HORMONE RESPONSE TO LUTEINIZING HORMONE RELEASING HORMONE
Journal of Endocrinology, 1978Perifusion experiments were performed to study the stimulatory effects of luteinizing hormone releasing hormone (LH-RH) on the release of LH from anterior pituitary tissue. Exposure of pituitary tissue from normal male rats to LH-RH (5 ng/ml for 5 min) induced a small release of LH; in tissue from ovariectomized rats receiving no pretreatment, the ...

Two varients of LH-RH, less than Glu-D-Phe-Trp-D-Ala-Leu-Arg-Pro-Gly-NH2 (I) and less than Glu-D-Phe-Trp-Ser-Tyr-D-Ala-Leu-Arg-Pro-NHCH2CH3 (II), have been synthesized by solid-phase methods. Both peptides strongly inhibit the LH-RH induced secretion of LH in an in vitro assay; however, only I proved effective in preventing ovulation in the 4-day ...

The secretion of luteinizing hormone-releasing hormone (LHRH) and its temporal association with pulses of luteinizing hormone (LH) was examined in ovariectomized prepuberal gilts. Push-pull cannulae (PPC) were implanted within the anterior pituitary gland and LHRH was quantified from 10 min (200 microliters) perfusate samples.

Endocrinology, 1978
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.

THE LUTEINIZING HORMONE RECEPTOR
Annual Review of Physiology, 1995▪ Abstract The luteinizing hormone receptor (LHR) is a member of the subfamily of glycoprotein hormone receptors within the superfamily of G protein–coupled receptor (GPCR)/seven-transmembrane domain receptors. Over the past eight years, major advances have been made in determining the structure and function of the LHR and its gene.
