What happens in men's bodies as they age? Unlike most healthcare issues, in which men's issues dominate resource allocation and share of voice, this is an odd one. Men's ageing issues are relatively under-discussed compared to women's ageing issues.

In part this is due to the different nature of changes. The decline in testosterone, the prime mover of changes men experience as they age, is not at all cliff-like as corresponding changes during menopause are for women. However, the decline is real, and so are the experiences. More irritability, stress and anxiety. More sleep issues. Loss of physical strength. Decline in sexual function.

A proper sweep through all questions around male ageing. Play on.
