Not Applicable

Completed

• Conditions: Neuroendocrine Reproductive Status

• Registration Number: NCT01058681
• Lead Sponsor: Centre Hospitalier Universitaire Vaudois

Brief Summary

This study will evaluate the potential effects of a changing metabolic environment on GnRH hypothalamic neurons, by performing studies of LH pulsatility (basal and during clamp studies) in different groups of male subjects fed isocaloric and hypercaloric diets. The participation of other gastro-intestinal tract hormones to these regulations will be systematically evaluated.
