Men and women

Man is a male human being, while female is a female person.

Mainly, the man produces the hormone testosterone and the woman estrogens. For this reason, each one develops different characteristics.

The differences between men and women can be appreciated in physical, biological, psychological, social and cultural terms.

DefinitionMale persons.Female persons.
ChromosomesGenetically they possess the XY sex chromosome pair.They have the XX sex chromosomes.
FertilizationIn fertilization, they provide a sperm that can be X or Y, which determines the sex of the baby.They provide an egg with an X sex chromosome.
Functioning of hormones
  • Higher testosterone level, causing a more aggressive and dominant character.
  • Testosterone levels also speed up metabolism, facilitating weight loss.
  • Your level of prolactin production is lower.
  • Hormonal changes alter the menstrual cycle, causing fickle moods and the development of the maternal instinct.
  • This generally makes it difficult for them to lose weight.
  • They produce more prolactin, responsible for producing breast milk and tears.
Primary (reproductive) sexual charactersThe gonads, the genital tract and the external genitalia: the penis and the testes.The gonads, the genital tract and the external genitalia: the vulva.
Secondary sexual characters
  • Lower voice and greater visibility of the Adam’s apple.
  • Increased amount of facial and body hair.
  • Ability to develop more muscles and more strength.
  • More developed chest and shoulders.
  • They are generally heavier and taller.
  • The voice is higher.
  • They have less amount of facial and body hair.
  • Relatively lower muscle capacity.
  • Developed breasts.
  • They are generally smaller in weight and stature.
Neural connectionsThey have more neuronal connections in the brain, the brain being larger and with a greater amount of white matter.

There is a greater predominance of the left cerebral hemisphere.

They have more connections between the right and left hemispheres of the brain.

This is usually denser and has more gray matter.

The use of the left and right hemispheres is balanced.

Body temperatureBecause they have greater muscle mass, their temperature is more balanced throughout the body.They more effectively maintain core body temperature.
SensesThey have greater visual acuity, but paradoxically they have less color perception.They have greater hearing and olfactory acuity.

They distinguish more colors than men.

SterilizationTo permanently prevent childbearing, vasectomies are performed.Female sterilization is done with the ligation of the fallopian tubes.
Fun facts
  • They better focus on one activity at a time.
  • They focus more on achieving goals.
  • They traditionally prefer action.
  • They have a higher sex drive, because sexual intercourse is perceived as another physiological function.
  • Tendency to baldness due to increased production of androgens.
  • They have the ability to perform multiple activities simultaneously.
  • They are more willing to get socially involved.
  • Generally, they prefer to converse and communicate both their feelings and their opinions.
  • They need more affection and emotion in their sexual relationships.
  • Less tendency to baldness due to lower androgen production.

What are men?

Men are all those people of the male sex , also known as males.

Normally, the term is used to refer to the adult person, although it also refers to man when it is generalized to the entire human race.

Men have very different biological and physiological qualities from women. The production of testosterone causes a man to have more body and facial hair, a wider chest and shoulders, a larger Adam’s apple, as well as an ability to develop muscles more easily.

In addition, men are the ones who determine the sex of the baby through the sperm cell inserted into the female ovum.

The primary sexual organs in men are external, while in women they are located internally in their body.

The male predominance in society has led to machismo . There are many trades, professions or activities that had traditionally been considered typically masculine in areas such as religion, politics, science or some sports, but with the passage of time, women have conquered almost all spaces.

Other stereotypes have changed over time, however some paradigms remain in force, such as:

  • Men are more rational and women are more affective and emotional.
  • Physical aggressiveness in men and verbal aggressiveness in women.
  • High sense of competitiveness in men and low sense of competitiveness in women.

What are women?

Women are female persons . Typically, the term “women” is used to refer to adults.

Women, due to the production of estrogens , have a narrow waist, developed breasts, less body and facial hair, wide hips, a wider pelvis and generally a higher voice than men.

Women are mostly in charge of reproductive work , taking into account pregnancy, childbirth and lactation that allows the survival of the human species.

Natural or artificial contraceptive methods have allowed the woman or the couple to plan their offspring, notably reducing the number of children produced and allowing women to freely exercise their sexuality.

Women were traditionally seen as the weaker sex, a paradigm that has been overthrown in most countries of the world.

Women have gained ground in different areas of society. In 1979, the United Nations Assembly approved the elimination of all forms of discrimination against women, becoming a great achievement for the fight for women’s rights in society.

The feminist movement has waged a constant struggle for the recognition of equal opportunities and rights between women and men.

The International Women’s Day is celebrated on March 8.
