The man

 A man is a male human. The term man is usually reserved for an adult male, with the term boy being the usual term for a male child or adolescent. However, the term man is also sometimes used to identify a male human, regardless of age, as in phrases such as “men’s basketball”.

Like most other male mammals, a man’s genome typically inherits an X chromosome from his mother and a Y chromosome from his father. The male fetus produces larger amounts of androgens and smaller amounts of estrogensthan a female fetus.Until about the eighth week of gestation, males and females are identical, then a surge of testosterone causes male fetuses to develop male sex organs, so without this wave of testosterone a male’s sex organ will not develop and no one would ever grow into a male body.
As a man continues to grow testosterone increasingly plays a vital role in his physical development. The presence of testosterone along with gonadotropins released by the pituitary gland in a male teenager during puberty stimulates spermatogenesis along with the full sexual distinction of a human male from a human female. This plays a big role in making a male body physically different from a female body as masculine secondary sex characteristics like body hair, facial, deeper voice, broader shoulders and chest, greater muscle mass, larger brain mass and volume, larger hands and feet, larger skull and bone structure, greater height develops. Additionally, researchers theorize that testosterone affects the brain and makes it quite different from the female brain.

In schools, children often argue about who is smarter or better– boys or girls, this type of argument doesn’t stop at the playground Teachers, doctors, psychologists and others continue to research the similarities and differences between how men and women learn, communicate and behave. The reality is each sexes learn and communicate and do things differently and none is actually better than the other.

Most expressions of sexual dimorphism in humans are found in height, weight, and body structure, though there are always examples of cases where this does not occur because some do not follow the overall pattern. For instance, when it comes to heights men are more likely to be taller than women, however there are many people of both sexes who are in mid-height range for species.
The body of a man differs to a large extent from the body of a woman and goes beyond what we can see physically. At cellular levels the male and female body differs. The sex of an individual is generally determined at the time of fertilization by the genetic material carried in the sperm cell, within every cell in the body is DNA and typically a human’s DNA is contains 23 pairs of chromosomes, the twenty third chromosomal pairs determine whether a body is male or female. If a sperm cell carrying an X chromosome fertilizes the egg, the offspring will typically be female (XX); if a sperm cell carrying a Y chromosome fertilizes the egg, the offspring will typically be male (XY).
So male cells have one X chromosome inherited from the mother and one Y chromosomes inherited from his father while on the other hand a female body has two X chromosomes except in rare case anomalies and are referred to as intersex. Scientists are still discovering how the differences between the DNA of men and women affect their physiology.
The concept of fatherhood and family exists in human societies, so when it comes to reproduction the male sex organs consist of the penis, testicles, vas deferens, and the prostate gland. The male reproductive organ produces semen which carries sperm and thus genetic information that unites with an egg within a woman. The sperm enters the uterus of a woman and then moves on to the fallopian tubes and goes on to fertilize an egg which develops into a fetus or child. Although the male reproductive organ plays no role during the gestation but it’s still a vital part of reproduction
According to self-help books and some relationship counselors, men and women communicate so differently that they might as well be from different planets. According to them when it comes to communication men don’t like to talk about feelings, and they especially don’t like to give the kind of comfort women like to receive in a crisis. Rather than offering support for another person’s feelings, men are allegedly dismissive and prefer to gloss over problems.
Although on average men are bigger, and quite stronger than women but research shows that Male life expectancy is slightly lower than female life expectancy, although the difference has narrowed in recent years. This is due to the physiological differences between men and women. Men are more likely to take more risk especially when compared with women for example according to the World Health Organization (WHO) three times as many men die from car accidents, two times as many men die from drowning and the list goes on. The way men approach life is quite different, for instance in relationships, women tend to build strong support network that would be beneficial to them during crises, this ultimately helps them handle life better and could also help them live longer, typically on the other hand men do not do that.
Over the years in many cultures when a male or female displays characteristics that is not typical to their gender it might become a social problem for the individual, for instance when a male exhibits excessive feminine behavior it is considered a sign of homosexuality, and the same thing goes for a female who exhibits masculine behavior. Additionally, the corresponding social condemnation of excessive masculinity is usually expressed in terms such as ‘testosterone poisoning” or “machismo”
The roles of men have constantly changed a great deal throughout history, men are believed to have assumed a variety of social and cultural roles which are likely similar across many groups of humans. In the era where agriculture was the primary source of jobs, the emphasis on the physical ability of the male was paramount, activities such as hunting, building of shelters, defense of villages and towns. Likewise, the roles for working men basically involved moderate to hard manual labor. But times have changed due to economic changes most developed countries have seen a great shift in jobs, now jobs require less physical demand due to industrialization therefore leading to a drastic reduction in the percentage of people required to do hard labor among the work force. Furthermore, till date there are still some exclusive positions and roles in the society that are reserved for men only but in recent decades, men in some societies now compete with women for jobs that traditionally excluded women.
