The release of sex hormones affect sexual development and fertility
The main female sex hormones is estrogen and progesterone is produced mainly in the ovaries in the reproductive period. Women in all stages of life, function and production of sex hormones is also varied.
Although the childhood of new active hormones at puberty, actually affects the body's hormones have since in the womb. If we look at, often newborn babies (male or female) have breasts that look great, sometimes followed by the release of a little milk.
This happens because the flow of the hormone estrogen from the mother to the fetus during pregnancy. However, this condition is only temporary and disappear within a few weeks. Although in some infants of women, breast enlargement may still be living up to children aged 2 years to finally completely disappeared.
Puberty. At this age the release of sex hormones will affect sexual development, sexual characteristics, and fertility. Important milestone of puberty in girls is breast budding growth, the emergence of hair in the pubic and armpit, and menstruation. Pubertal process takes approximately 4 years.
During puberty, a girl from the pituitary gland increases the secretion of two key hormones, namely folicle stimulating hormone (FSH) and luteinizing hormone (LH). Both types of hormones are essential for the release of eggs and menstruation.
Adulthood. In addition to helping to control ovulation, fertilization, and pregnancy, estrogen maintains bone strength and helps regulate cholesterol. Progesterone works with estrogen to prepare the body of a woman facing conception, pregnancy, and helps regulate the menstrual cycle.
This hormone also plays an important role in the growth and regulate body fat distribution in women so that more fat deposits in the thighs, buttocks, and hips. In the meantime, testosterone helps build muscle and bone.
Pregnancy. If the egg can be fertilized and pregnancy, hormones change dramatically in the body of a woman. Usually decreased levels of estrogen and progesterone that are common at the end of the menstrual cycle does not occur. Instead, a new hormone, human chorionic gonadotrohin (HCG), produced for the development of the placenta, stimulate the ovaries produce more estrogen and progesterone are necessary during pregnancy.
After birth. After birth, levels of estrogen, progesterone and other hormones plummeted, causing physical changes. Uterus will return to its original size before pregnancy, pelvic floor muscles increases, and the volume of blood circulation back to normal. This dramatic hormonal changes often lead to postpartum depression.
Menopause. Other significant hormonal changes that occur when women enter menopause. In the 3-5 years before the end of the menstrual cycle, normal ovarian function begins to decline. This makes the menstrual cycle shorter or longer. Sometimes the ovaries produce less estrogen so it does not thicken the uterine lining does not occur until the end of menstruation.
Overall survival in women, estrogen helps protect the heart and bones, as well as keeping the breast, uterus, and vagina in a healthy condition. That is why, the decline in estrogen levels during and after menopause can affect health, but also trigger the uncomfortable symptoms.
Loss of estrogen causes a large number of women at higher risk of heart disease and osteoporosis. Another problem is the vagina to become dry and uncomfortable during intercourse.
