ABSTRACT

It had been established that the sexual structure of a person was determined by the type of hormonal production, what gave biological specificity of the estrogens to women and androgens to men, but recently this functional specificity has lost base due to the biological activity described in different tissues of men and women, today known as endocrine paradox. There are hormonal events that show the need of estrogens to correct development in men and androgens to women. In men the absence of effect of the estrogens produces deficient ossification of skeleton, persistence of the growth cartilage and osteoporosis in adult men. In women the production of androgens by suprarenal glandules is required to obtain the complete feminization. In women with chirurgic-induced menopause, the relation between androgens and the stimulation of sexual response has been established.
It has been described a hormone called kisspeptin, that it is attributed the potential to initiate the puberty because stimulates the hypothalamus; in absence of this hormone the women do not present their secondary sex characters, remaining immature sexually. The understanding of individuals needs of androgens and estrogens contribute to improve the control and care of the patient with hormonal deficiencies in any phase of the life.


Key words: endocrine paradox, androgens, estrogens, kisspeptin.
