Universal correlates of beauty
Strong correlations between attractiveness and particular physical properties have been found across cultures. Despite significant variation, there nonetheless exists a tremendous degree of agreement among cultures as to what is perceived as attractive when it is associated with human health. Healthier looking skin is universally associated with attractiveness. Infants, who presumably have not yet been affected by culture, tend to prefer the same faces considered attractive by adults.[4] These findings are used to imply that a large part of attractiveness is determined by inborn human nature - not nurture.
Determinants of male physical attractiveness
Physique
Preference can also emerge for muscularity, though research performed at McLean Hospital has shown that Western men have a tendency to overestimate the amount of muscle considered ideal by women by as much as thirty pounds, whereas Asian men collectively do not exhibit such a misconception.[6]
A normal level of the hormone testosterone is a possible indicator of good sexual health. In the absence of normal testosterone levels, a man may exhibit physical symptoms of less muscle development and physical height reduction.
For heterosexual females, homosexual males and bisexuals of both genders across the world, the one near-universal sexually attractive feature of a man is a v-shaped torso: a relatively narrow waist offset with broad shoulders. While some cultures prefer their males huskier and others leaner, the rule of a v-shaped torso generally holds true.[7]
