Yes, on average, boys are typically stronger than girls due to biological differences, primarily greater muscle mass and testosterone levels, with men generally exhibiting 10-30% more strength and power in athletic tasks, especially in the upper body, though training and individual variation exist. These differences become more pronounced after puberty, but girls can still be strong in their own ways, and individual strength varies.
Before, during, and after puberty, boys are stronger than girls on average. The sex difference in muscle strength increases markedly with male puberty, averaging ∼10% in 5–10‐year‐olds and then ∼40% in 14–17‐year‐olds.
Women athletes are known to be less strong and powerful than equally trained men [1], muscle strength of women indeed, is typically reported in the range of 40 to 75% of that of men [2]; women are also known to be less powerful than equally trained men.
A consistent result from this literature is that men are significantly stronger than women on all tests of muscle strength, but the difference is greater for tests of upper-body than lower-body muscle strength.
Men generally have more muscle mass than women due to higher levels of testosterone, which promotes muscle growth and development. Additionally, men typically have a greater proportion of fast-twitch muscle fibers, which are associated with strength and power.
In general, boys have a significant increase in bone and muscle growth and a simultaneous loss of fat in the limbs under the influence of testosterone. In agreement with the literature, we have found that male subjects are higher, heavier and less fat than female subjects.
In terms of absolute strength – that is, without regard for body size, weight or composition – the average man tends to be considerably stronger than the average woman. Specifically, the absolute total- body strength of women has been reported as being roughly 67% that of men.
Historically, power has been distributed unequally. Power and powerful positions have most often been associated with men as opposed to women. As gender equality increases, men still hold more power, including in politics and athletics.
Out of the 74 countries we examined, each one had women having a higher share of their skills being soft skills than men. This is a gap that has grown over the last eight years. Men hold higher shares in disruptive tech skills and other tech skills.
Gender differences in health have been reported in several domains. Since the 1970's, biomedical literature has shown that women suffer from higher morbidity than men due to acute and chronic physical and psychiatric diseases (8, 64–68).
Interesting to know, intelligence quotient (IQ) in male and female is almost same, and both can further improve their IQ [7]. In the hierarchy, male reach at top with their intelligence, hardwork, success and skills whereas females reach on top of the hierarchy through intelligence, skills, hard- work and beauty.
Men are generally physically stronger. Women generally more adaptive. We do not need to take away from one to make the other relevant.
Studies have shown that men tend to have larger eyes than women, with a larger corneal diameter and a wider angle between the eyes, known as the interpupillary distance. These differences may contribute to a slight advantage in peripheral vision and depth perception for men.
A newly published study by Brigham Young University researchers found that boys run faster than girls in the 1,600-meter race from ages 6 to 12, with an average performance differential of 7.7%, augmenting the body of evidence indicating that the innate male edge in athletics begins before puberty.
In humans, the natural sex ratio at birth is slightly biased towards the male sex. It is estimated to be about 1.05 worldwide or within a narrow range from 1.03 to 1.06 males per female at birth. The sex ratio for the entire world population including all ages is approximately 101 males to 100 females as of 2024.
The typical girl is slightly shorter than the typical boy at all ages until adolescence. She becomes taller shortly after age 11 because her adolescent spurt takes place two years earlier than the boy's.
It is now recognized that there are no significant sex differences in average IQ, though performance in certain cognitive tasks varies somewhat between sexes. While some test batteries show slightly greater intelligence in males, others show slightly greater intelligence in females.
"What we have found is that women, in many different tasks, process information about five times faster than men, and use much less of their brain to do identical cognitive performance."
This was evidenced both by their own reports of how much they worked and by their activity trackers. Women walked on average just over 12,000 steps per day, while men walked just over 9,000 steps. So men also worked hard, but less so than women.
Masculinity is conceptualized as dominant, virile, and powerful, and femininity as passive and submissive therefore the expectation is that the male will be the sexual seducer and the female will be seduced (Levine & Koenig, 1980).
At a psychological level we're also told that women are more interdependent as people whereas men are considered to be more independent. Both of these theories would lead us to believe that, generally speaking, women are more loyal than men.
Recent data from the Centers for Disease Control (CDC) suggests that the average weight of men in the US is 199.8 pounds. The average weight for women is 170.8 pounds.
Intensity & Expression: Yes, women tend to report greater emotional intensity—more frequent thoughts about their partner and slightly stronger romantic emotions (Bode et al., 2025). But this doesn't mean men love less. In fact, their love often takes on a quieter but equally powerful form.
