Hypothalamic integrity increasingly is being recognized as a marker of healthy longevity in rodent models. Insight into hypothalamic function in humans with exceptional longevity can be gained via investigation of the hypothalamic–pituitary-testicular (HPT) axis in men with exceptional longevity. This study aimed to characterize the HPT axis function, defined by levels of testosterone (T) and luteinizing hormone (LH), in 84 Ashkenazi Jewish men aged 90–106 years. We found that 94% of men exhibited preserved hypothalamic–pituitary function, as evidenced by either normal testosterone and LH levels (25%) or an appropriate rise in LH in response to aging-related primary testicular dysfunction (69%), a hormone pattern mirroring female menopause. Total T level was not associated with metabolic parameters or survival. These results demonstrate a high prevalence of testicular dysfunction with preserved hypothalamic–pituitary function in men with exceptional longevity. Thus, the role of hypothalamic integrity and HPT axis in healthy aging warrants further investigation.
