The woman (from the lat. Mulĭer, -ēris) [1] or female (lat. Femĭna) [2] is the human being of female sex. She has biological differences with the male, such as a narrower waist, wider hips and a wider pelvis, different distribution and amount of hair and adipose tissue. Her genitalia are different and her breasts, unlike the male, are developed. The woman also refers to cultural and social differences attributed to her by gender. International Women's Day is commemorated on March 8.


X chromosome and hormones

After fertilization during the first cellular stages, it is defined at the biological level if the future being will be male or female, resulting in this case that chromosome 23 is type XX, determining the future development of the infant and adult, generating ovaries and external sexual organs such as the vulva and internal like the vagiba. Later this will trigger a hormonal process secreting several hormones, some of which are responsible for the secondary sexual characteristics of the woman that will occur from adolescence. A large number and interaction of hormones are part of the biology of women, the main one being estrogen, which affects secondary sexual characteristics.

Female gender

The female reproductive system allows the woman to be fertilized by the male's sperm and thus the transmission of genetic information through the ovum. The primary sexual organs of women are internal as opposed to those of men which are external. [3]

Secondary Sex Characters

The woman's body is characterized by the presence of breasts with mammary glands, the purpose of which is to feed future children. The hip is different from the man, it is wider than in the male to allow the exit of a new human being at the end of the gestation or pregnancy. The following characteristics can be found in the female sex: [4] Developed breasts and larger nipples. On average, less growth in height than in men. Higher level of subcutaneous fat, especially in the face, buttocks and thighs. Wider hips. Development of body or androgenic hair to a lesser extent than men, mainly on the legs and armpits. Pubic hair grown in a triangular shape, in the genital area covering the vulva and the mons pubis. Voice higher than that of the male

Women's Health and Procreation

The right to health is considered a human right of women that implies comprehensive care in all aspects and, specifically in the particulars of women's health, reproductive rights, access to sexual education and free access to family planning when desired. One of the goals of women's health is to prevent maternal mortality. [5] [6]

Reproduction, reproductive effort and demographics

Women have carried out and carry out the effort of reproductive work that allows the survival of individuals and societies. [7] Throughout history and until recently, in order to guarantee social survival and in a context of extremely high mortality (both in crude mortality rate and in infant mortality), it has been necessary to maintain a very high birth rate (both in the crude birth rate and in the fertility rate) to guarantee a sufficient replacement of the populations. [8] The improvement in nutrition, the generalization of hygiene, sanitation and the diffusion of medicines have been decisive for the strong growth of the world population that has gone from almost 1 billion in 1800 to more than 6 billion in the year 2000 and 7000 million at the end of 2011.
