Abstract : Neuroendocrine studies of sleep and dreaming in normal young adult men were performed. The patterns of release of the two gonadotropins, luteinizing hormone and follicle stimulating hormone, and prolactin, were studied in reference to the secretion of testosterone from the testis. It was found that the secretion of luteinizing hormone and testosterone were not closely related throughout the night. Testosterone levels increased during the sleep period, whereas luteinizing hormone on the average did not increase during the night. It did appear, however, that the initial rise in testosterone was triggered by a secretory episode of luteinizing hormone, but then testosterone continued to rise independently of further secretion of luteinizing hormone. Follicle stimulating hormone and prolactin, the other two anterior pituitary hormones studied bore no clear relationship to either luteinizing hormone or testosterone. These studies are part of a continuing program of research into biochemical and psychoendocrine correlates of stress, sleep and dreaming, and other central nervous system states in specialized populations as well as in normal subjects.
