Why Do Men Exist? Discover The Reason

Why do men exist? The answer to this question has puzzled scientists for years.

From a purely biological standpoint, it seems kind of perplexing. After all, males’ only contribution to reproduction is their sperm.

So, why does sexual reproduction need two sexes? Let’s explore some possible theories.

The existence of men has long been a puzzle for scientists due to the inefficient and costly method of sexual reproduction. However, one possible explanation for the existence of men is their role in evolution as contributors to reproduction.

In many species, sperm is the only contribution that males make to reproduction. Despite its inefficiencies and costs, sexual reproduction has evolved to rely on a partner regardless of the sex.

According to British scientists, males are required for the process of sexual selection, which helps species to ward off harmful mutations and maintain genetic diversity.

Therefore, the existence of the male sex can be attributed to the crucial role they play in reproduction and the need for genetic diversity to survive and evolve.

Biological Reasons

The existence of men has always puzzled biologists and scientists due to the inefficiency of sexual reproduction. This is because in most species, males only contribute sperm to reproduction, and this process is both costly and inefficient.

However, recent studies have shown that males play an important role in “sexual selection,” which helps species improve their genetic fitness and ward off disease and disorders.

Cultural and Social Reasons

Men exist not just for biological and evolutionary reasons, but also because of cultural and social factors. While women were primarily responsible for child-rearing and household tasks in ancient times, men were hunters and providers.

As societies evolved, this trend continued, with men often being seen as stronger, more aggressive, and better equipped to handle physically demanding work. This led to men taking on roles such as soldiers, farmers, and builders.

In many cultures, men have also been the primary decision-makers and leaders, with women having fewer rights and opportunities. This has contributed to the perpetuation of patriarchal systems, where men hold more power and influence in society.

However, there has been progress towards gender equality in recent years, with women breaking down barriers and taking on roles traditionally reserved for men. As societal views continue to evolve, it is important to value individuals for their skills, abilities, and character, rather than solely based on their gender.

Behavioral and Psychological Reasons

The existence of men has puzzled scientists for a long time due to the inefficiency and costliness of sexual reproduction. However, one explanation is the process of sexual selection, which requires the presence of males to help species ward off extinction.

From a purely biological perspective, the existence of the male sex may seem confusing, but it serves a vital role in promoting genetic diversity in the population.

Gender is produced and reproduced through everyday social practices and is not a set of characteristics or traits. Men and women differ in various fields, such as mental health, cognitive abilities, personality, emotion, sexuality, and tendency towards aggression.

Understanding the differences between men and women can be attributed to evolutionary psychology, which is the most widely accepted theory.

Evolutionary psychologists argue that gender differences are a result of different evolutionary pressures on men and women. For instance, men are more inclined towards aggression because it helped them to defend their territory and protect their women and offspring from other threats.

Women, on the other hand, are more nurturing and empathetic because it helped them to form social bonds with other women in their community.

Despite behavioral and psychological differences, men play a crucial role in promoting genetic diversity in the population, which is essential for the survival of species.

Health and Well-being Reasons

Men exist not only for reproductive purposes but also for their unique health and well-being needs. Physical activity is essential in maintaining good health, that’s why men’s existence is critical to performing a variety of physical activities such as lifting heavy equipment, running long distances, and exercising for long periods.

Moreover, men’s health is different from women. Different factors contribute to men’s health, such as mental health challenges, addiction, problem gambling, workplace challenges, relationship conflict, racism, and discrimination.

Men tend to suffer more than women from cancer and heart disease, which are key factors in mortality. That’s why their existence is essential in keeping the balance of health and well-being in society.


Men exist as an important contributor to sexual selection, which helps the species to adapt over time. From an evolutionary and biological perspective, the existence of men provides a way for reproduction, but beyond that, gender identity and relations are shaped by cultural practices.

While psychological gender differences between men and women exist, one’s sex or gender has little to no bearing on personality, cognition, and leadership. Men’s health concerns are also important, as they often suffer from specific diseases like heart disease, while women have higher rates of chronic illnesses like depression and anxiety.

Frequently Asked Questions

Why do we have males?

Biologists have long puzzled about why males exist since in many species, sperm is their only contribution to reproduction.

Do we need males to reproduce?

No, we don't need males or their sperm to reproduce. Virgin birth or parthenogenesis happens in numerous plant and animal species.

When were males created?

The first sex-determining genes appeared in mammals about 180 million years ago, and the Y chromosome, which distinguishes males from females at the genetic level, appeared at that same time.

What percentage of men procreate?

According to the U. S. Census Bureau, about 61.6% of men age 15 and over are fathers, and of those, 72.2 million men have a biological child. More than one in four men have a biological child under the age of 18.
