THE estrogen It is a female hormone, produced from adolescence onwards, when the first secondary sexual signs begin to appear in a woman's body. This hormone acts on female anatomy, cells and behavior and its production is continuous until menopause.
The maturing ovarian follicle is responsible for the production of estrogen, which is released in the first phase of the menstrual cycle. The hormone is responsible for, among other things, female skin texture, bone development and the balance between blood fats (cholesterol and HDL).
Estrogen in pregnant women
In pregnant women, the amount of estrogen increases considerably to stimulate the growth of the uterine myometrium, making it suitable for childbirth. At mammary glands also tend to grow. The hormone is also able to cause relaxation in the pelvic ligaments, pubic symphysis, pelvic bones – seeking to more comfortably accommodate the expanding uterus – and stimulates the production of progesterone.
More clearly, estrogen causes cells in many parts of the body to proliferate, which makes it possible, for example, for the smooth muscle of the uterus to increase to the point of tripling in size. In addition, it enlarges the vagina, promotes the development of the labia and allows the pubis to be covered with hair. The hormone is also responsible for the enlargement of the hips, breast development and the accumulation of adipose tissue in certain regions such as thighs and hips, characterizing the female body.
The lack of estrogen can lead to a decrease in the brightness of the skin and redistribution of body fat to different parts, characteristics of men, such as the belly. In addition, a low concentration of the hormone can promote vaginal dryness - affecting sexual intercourse - and heart attacks or cardiovascular diseases characteristic of men, due to the lack of balance between blood fats, cholesterol and HDL.
Depression and irritability are also caused mainly by the lack of estrogen in the body. Bone decalcification problems can also have their origin in the lack of the hormone, since it is responsible for fixing calcium in the bones.
For being responsible for the feminine bodily aspects, research shows that women with a higher concentration of estrogen tend to be more beautiful.
