Dose-Response relationship of luteinizing hormone to luteinizing hormone—releasing hormone in man [PDF]

Journal of Clinical Investigation, 1971
In previous clinical studies with highly purified porcine luteinizing hormone-releasing hormone (LH-RH), administration of the somewhat arbitrarily chosen doses of 700-1500 mug resulted in increased serum levels of luteinizing hormone (LH) and follicle-stimulating hormone (FSH).

Transcriptional Profiling of Luteinizing Hormone Receptor-Deficient Mice Before and after Testosterone Treatment Provides Insight into the Hormonal Control of Postnatal Testicular Development and Leydig Cell Differentiation [PDF]

, 2010
Luteinizing hormone (LH) is a key regulator of male fertility through its effects on testosterone secretion by Leydig cells. Transcriptional control of this is, however, currently poorly understood.
