Older men’s sexual priorities extend well beyond erectile function

A web-based survey of 6,000 Japanese men aged 50 or older found that sexual arousal was the function they most wanted to preserve, while erection became more highly valued as erectile function worsened. Erection showed the earliest age-related decline pattern, whereas ejaculation was the function most often reported as lost in older age.

Cortisol may distort the body signals that guide risky choices in men

In a randomized study of 109 young adults, researchers measured cortisol responses, skin conductance signals, and risk-taking during the Iowa Gambling Task after an acute psychosocial stressor. Cortisol reactivity altered how anticipatory bodily signals related to risky choices in men, although the stress condition did not increase overall risk-taking.
