Official title
The Effect of Mixed Exercise and Metabolic Stress Upon Pituitary Secretion in Relationship to Age in Healthy Men: a Pilot Study
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Aging in men reduces the amount of luteinizing hormone (LH) and testosterone (Te) secreted in each burst. Stress-associated mechanisms introduced by acute illness and chronic disease decrease LH and Te secretion further. A major unresolved issue is whether the aging process heightens the negative effects of a stressor (whether physical or metabolic) upon LH and Te secretion. This study will assess LH and Te secretion in response to a physical stressor (maximal exercise) and a common metabolic stressor (hyperglycemia) as a function of age in healthy men ages 18-80 yr.
