Neuroendocrine control of human reproduction in the male

The traditional difficulty in studying the neuroendocrine control of reproduction in the human male has been the inability to tease out the hypothalamic from the pituitary component of this neuroendocrine system. The use of multiple models, each with its own strength and weakness, represents an overlapping approach that has permitted further insights to be gained into the hypothalamic control of the neuroendocrine regulation of gonadotropin secretion in the human. Such an insight is an important prerequisite to the understanding of the pathophysiology of various disease states, the unraveling of a control of FSH secretion by GnRH vs other modulators, and the subsequent design of rational therapies for male reproductive disorders.
