Facial features

Studies have shown that ovulating heterosexual women and gay men prefer faces with masculine traits associated with increased testosterone, such as heavy brows, wide jaws, and broad cheekbones. Women who are in the late luteal or early follicular phases of the menstrual cycle (or those taking hormonal contraception) do not prefer masculine male faces.[7][8][9] These are suggested to be a reliable indication of good health, or, alternatively, that dominant- and masculine-looking males are more likely to achieve high status.[10] However, the correlation between attractive facial features and health has been questioned.[11] Also, females tend to prefer different facial traits in short-term and long-term partners, and sociocultural factors, such as self-perceived attractiveness, status in a relationship and degree of gender-conformity, have been reported to play a role in female preferences for male faces.[12]
[edit] Symmetry

Symmetrical faces and bodies may be signs of good inheritance to women of child-bearing age seeking to create healthy offspring. Some studies suggested that women at peak fertility were more likely to fantasize about men with greater symmetry.[13] Studies suggest women are more attracted to men with symmetrical features, and noticed correlations between symmetry and other variables typically associated with masculinity, such as greater height, broader shoulders, and smaller hip-to-waist ratios.[14] Facial and body symmetry may indicate good health, which is a desirable feature.[14] The symmetrical nature of a male partner may be a variable influencing whether a woman, during sexual intercourse, is able to achieve an orgasm; one study suggested that orgasmic frequency increases from 30% to 75% when their male partners were described as more symmetrical.[15]
[edit] V-shaped torso and muscularity

The mesomorphic physique of a slim waist, broad shoulders and muscular chest are often found to be attractive.[16] A 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. Consistently, men with a waist-to-shoulder ratio of 0.75 or lower are viewed as considerably more attractive than men with more even waists and shoulders.[17] A degree of hirsuteness and a waist-to-shoulder ratio of 0.6 is often preferred, when combined with a mesomorphic physique.[18]

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 have reduced height and muscularity.
