IT when they see studies analyzing that the attractiveness of good-looking men can be explained through evolutionary biology, where traits like facial symmetry, strong jawlines, and broad shoulders signal genetic health, high testosterone levels, and physical fitness, all of which are desirable for reproductive success. Symmetrical faces indicate developmental stability and genetic fitness, while masculine features such as pronounced brow ridges and jawlines suggest dominance and fertility, qualities linked to successful mate selection. A high shoulder-to-hip ratio (SHR) signals strength, stamina, and the ability to protect and provide, enhancing a male’s appeal as a potential mate. Grip strength, a proxy for overall muscle strength, further reinforces health and vitality, key markers of good genes. Additionally, sexual experience correlates with social status and sexual competence, further enhancing attractiveness due to mate value and the ability to attract mates. These traits collectively align with the good genes hypothesis, where individuals with these features are preferred for their ability to ensure healthy offspring, making them more attractive from an evolutionary standpoint
One of the many studies I am referring to:

The study you provided explores the relationship between men's facial attractiveness and various indicators of individual fitness, including body morphology (specifically shoulder-to-hip ratio or SHR), grip strength, sexual behavior, and the number of sexual partners. Below is a more specific breakdown of the research with additional detail about the various aspects mentioned.
Abstract
The study investigates whether certain physical cues in men's faces correlate with other measures of individual fitness. These measures include their
shoulder-to-hip ratio (SHR), which indicates a person's body shape,
grip strength, and
sexual behavior (specifically sexual history). The
facial photographs of male college students were rated for
attractiveness by female college students. A
significant relationship was found between the ratings of facial attractiveness and various physical characteristics. Notably, males with attractive faces tended to have more
masculine body types, indicated by
wedge-shaped, masculine SHR. They also scored higher on grip strength and had a greater number of sexual partners, supporting the idea that facial features can provide clues to a man's
overall fitness and hormonal status.
Introduction
This section connects the evolution of primates to human perceptions of faces, highlighting how
visual cues, especially faces, play a critical role in mate selection. Primates developed a reliance on their
sense of vision, and humans have evolved specialized mechanisms for
facial recognition. Studies show that we tend to find faces with
bilateral symmetrymore attractive, which is considered a sign of
genetic fitness, health, and fertility. This preference for symmetrical faces may be evolutionary, as such faces correlate with
better health, longevity, and a
higher probability of successful reproduction.
Further research has shown that men with more symmetrical faces also tend to have
better overall health (e.g., higher sperm motility and count), and
females tend to rate
masculine features (like broad shoulders and narrow hips, which are indicated by
SHR) as more attractive. Such body configurations are linked with higher levels of
testosterone, a key driver of
masculine traits.
Results
The study revealed several
strong correlations between facial attractiveness and physical fitness markers:
- Body Morphology (SHR):
- Males with high shoulder-to-hip ratios (SHRs)—characterized by broad shoulders and narrow hips, a common indicator of masculine body type—were rated as more attractive by females. Attractivenesscorrelated significantly with higher SHR (r = .512, p <.01).
- SHR was also positively correlated with grip strength (r = .381, p <.02), suggesting that a more masculine body shape is linked to higher physical strength.
- Grip Strength:
- Grip strength was used as an objective measure of physical fitness, as it is associated with overall healthand vitality. Males with stronger grip strength were rated as more attractive by the females (r = .323, p <.05).
- Moreover, higher grip strength correlated with more sexual partners (r = .317, p <.05), suggesting that men who are physically stronger are likely to have more sexual experience.
- Sexual Behavior:
- The number of sexual partners also correlated positively with facial attractiveness (r = .360, p <.03). Men who had more sexual partners were considered more attractive by the female raters.
- A regression analysis showed that facial attractiveness could predict around 26% of the variance in shoulder-to-hip ratio (SHR) and 10% of the variance in grip strength, reinforcing the connection between physical appearance and indicators of fitness.
Discussion
- The study's findings strongly suggest that female facial ratings of male attractiveness reflect significant aspects of masculinity, such as body morphology, strength, and sexual behavior. This highlights the notion that facial features are not only important for interpersonal attraction, but also serve as a signal of underlying fitness.
- The study found that facial attractiveness accounted for a substantial proportion of the variance in body configuration (SHR) and grip strength, suggesting that the face serves as a reliable indicator of genetic qualityand fitness.
- The findings are consistent with the hypothesis that facial features are reliable indicators of health and sexual vitality, which may have been selected for in evolutionary history to increase reproductive success.
