Childhood
Although we step in the hormones of puberty thinks rather, they influence our body also during the early childhood. Newborn children (boy like girl) have possibly increased breasts easily, sometimes a little milk production accompanied, by the female hormone estrogen in the body of the mother, by the placenta during the gestation and stimulatingly in the breast of the baby. This mostly disappears after a few weeks, but in mild baby girl breast enlargement is able again sometime during the first two years, this time because of the child even hormones influence mammary tissue. This mammary enlargement can dwindle wax and repeats about months or even years, before they, finally, disappear during the childhood.
Female sexual hormones
The most important hormones in the ovaries are female sex hormones produced like (sexual hormones) and both most important ones are known estrogen and luteal hormone. The ovaries then produce some of the male hormone testosterone. During the puberty, estrogen stimulates mammary development and causes of the vagina, womb (uterus) and Fallopian tubes (carry, that eggs in the womb) to mature. It also plays a role in the growth push and changes the distribution of fat in the body of a girl, is typically deposited to originating ones in more around the hips, breech and femur. Testosterone helps, muscle growth and promote osseous growth.
From the puberty, LH, FSH, estrogen and luteal hormones play a deterministic role mining with the regulation of a Mrs. menstrual cycle, the results in her time. Every single hormone follows own pattern, rising and falling at different points of the cycle, but together they produce a predictable chain of events. An egg (from several hundred thousands in every ovary) becomes ‘too ripe’ (old people) and is released from the ovary, his trip around the Fallopian tube and begin by in the womb. If the egg is not fertilized, the estrogen and luteal hormone of the ovaries start to fall. Without support of the effect of these hormones, is the lining of the womb, which fully from blood, scales, in a stage.
After the child birth
After the child birth then, what? Estrogen, luteal hormone and other hormones drastically fall, what to a row of physical changes. The womb shrinks again on his non-charged size, pelvic muscle tone improves ground and the volume of the circulating blood by the body again normally. The dramatic changes in the hormone could therefore play a role reflector with the genesis of postnatal depressions, although no real differences were found in the hormonal changes of the women, not, and not to get postnatal depression. It can be that some women are affected from these hormonal variations lighter than others.
By the way hormonal variations, even if they object of examinations for many years we do not know yet Whether they have responsibly for the wide spectrum of physical and psychic symptoms the we are today the premenstrual syndrome or PMS. Nobody doubts that many women sensitive breasts, bloating, irritability, bad mood and other symptoms experience in the guidance up to a period, but Whether this by hormone variations, changes in the brain chemicals, social and emotional problems or a combination of everybody three is a question of the debate.
Puberty
In the puberty hormones will begin for big, lasting changes in a body of the girl make. Their breasts become bigger and take the figure of an adult female breast. They develop shoulder hairs and pubic hairs and will agree perceptibly greater than to push important growth appears. Finally, her stage begins, as a rule as a push growth starts to slow down. From beginning till the end, the process of the puberty at least four years, her last as a rule not unexpectedly, that some girls difficulties of the adaptation to changing body, sexuality to threshold countries, the beginning of the fertility and a certain emotional turbulence , as they fit of the childhood up to youth the old person.
All machines which will run through puberty with the child for the birth available, but for many years the body holds them switched off Sometime, the mechanism which prevents that winds of the puberty were kept in check down, and hormones, before it begin with, her influence on the body exert. A part of the brain, the hypothalamus begins hormone pulse, all of 90 minutes or so publish. This stimulates the pituitary gland gland (also in the brain) onto luteinizing hormone (LH) and follicle-stimulatory hormone produce (FSH) to produce the cause again a girl other hormones the ovaries.
Gestation
If the egg is released from the ovary and fertilized a gestation results of a woman hormones change drastically. The usual decline the luteal hormone estrogen and at the end of the cycle does not appear, seen so that no time is. A new hormone hCG (human chorionic gonadotropin) which produces from developing placenta moves the ovaries on the higher levels and the luteal hormone estrogen which are necessary, around a gestation are to be received to produce. Most of the gestation test sets are conceived so as HCG in the urine of a woman recognize, and many can therefore fetch in tiny amounts Thus only one day or after the first non-appearance of the monthly period.
With the fourth month of the gestation the placenta from the ovaries takes about as the main producer of estrogen and luteal hormone. These hormones cause the womb lining of the to thicken, raise the volume of the circulating blood (in particular the care of the womb and breasts), and relax the muscles of the womb enough to make room for the adolescent baby. In the time of the delivery, other hormones come into play which contribute to it to promote the womb contract during and after the work, as well as the production and emission of mother’s milk.
