At what age do girls start ovulating? As we all know, women have follicles in their bodies after birth, but they don't start to develop and grow until the first menstruation. Let's take a look at how older girls start ovulation and related information.
At what age do girls begin to ovulate 1? Most girls have menarche in12-1April, but during this period, the menstrual cycle is irregular, and the menstrual flow will be less, sometimes only once every few months. But there is ovulation at menarche, so girls usually ovulate at this time.
But after all, it is still in the process of long body and initial development, so a mature egg will be mature after the age of fifteen or sixteen and when the menstrual cycle is relatively regular and stable.
If the menstrual flow of girls is unstable and irregular, and this phenomenon often occurs, they still need to go to the hospital for hormone endocrine examination. If there is any abnormality, she should be recuperated or treated as necessary.
Girls have menarche, so parents must pay more attention. After all, there are a lot of menstruation knowledge, and children who don't understand it often have fears and fears. It is necessary to explain to children that this is a unique physiological phenomenon of normal girls. And help children do menstrual health care to ensure good health.
Generally, girls will ovulate at the age of 1 1 to 16, and the specific ovulation time varies from person to person.
Under normal circumstances, women may have menarche around 1 1 ~ 16 years old, and ovulation has already begun at this time, because everyone's physical condition is different, and the intake of nutrients is different, and the ovulation time will be different. Ovulation is a hormone regulation of the receptor's endocrine, which occurs about 14 days before the next menstrual cramp. Eggs can be discharged by two ovaries in turn, or by one ovary, and can be combined with sperm to form an embryo after discharge.
However, if the patient has not menstruated since the age of 16, it may be that she has not ovulated, so we should pay attention to it and go to the hospital in time to rule out whether it is caused by polycystic ovary syndrome. Polycystic ovary syndrome (PCOS) is a common female endocrine disease, which is easy to lead to ovulation. It is necessary to take ethinylestradiol cyproterone tablets and other drugs under the guidance of a doctor.
It is suggested that girls should develop good work and rest habits, avoid staying up late for a long time, and don't have too much pressure.
Because of the influence of living habits, living areas and other factors, the age of each woman's first menstruation is different. Generally, the age of menarche is between 12 and 16. Ovulation will start as long as menstruation comes, and the ovulation period is generally around 14 days before the next menstruation.

But after all, it is still in the stage of body growth and initial development, so the mature eggs need to be after the age of fifteen or sixteen, and the eggs will be more mature when the menstrual cycle is relatively regular and stable.

At what age do girls start ovulating? 3. At what age do girls start to have normal follicles?
When girls enter puberty, the first menstruation is called menarche, at which time girls will have mature follicles, and the age is generally between 13- 15. Healthy girls can also have menarche in early11-1February, and menarche in late seventeen or eighteen years. Sooner or later, the age of menarche will be affected by physical and nutritional status, and those who are weak and malnourished can postpone menarche.
In fact, girls have a certain number of follicles in their ovaries from the moment they are born. The number of these follicles is certain, but before puberty, women's ovaries are undeveloped. After puberty, women's ovaries gradually develop into mature eggs, which are discharged from the ovaries, thus having fertility.
In fact, the follicles in girls' ovaries are also in the process of development before puberty. Follicles will grow up with the growth of the little girl, until the follicles in the ovary gradually grow up and mature, and one or more dominant eggs will mature and expel eggs every month.
The number of follicles in women is fixed. As time goes on, the number of follicles in the ovary will gradually decrease, thus gradually reducing the fertility of women. However, follicles will not be fully mature and excreted from the ovary, leaving some immature follicles after menopause.
When does the little girl have follicles?
The follicular phase is not equal to the ovulation phase. The follicular phase and ovulation phase are two completely different periods. The follicular phase refers to the period when an egg is first produced and matured, while the ovulation phase refers to the period when a female egg is excreted after it matures. Generally, the follicular phase lasts from the last menstrual stop to the ovulation day of the ovary, which takes about 10- 12 days.
During this period, the granulosa cells of the follicle produce estrogen between FSH and LH, which will make the endometrium grow very fast, the blood vessels proliferate, and the glands in the body become longer and wider, but this hormone will not produce too much.
In fact, the follicles in girls' ovaries are also in the process of development before puberty. Follicles will grow up with the growth of the little girl, until the follicles in the ovary gradually grow up and mature, and one or more dominant eggs will mature and expel eggs every month.
The number of follicles in women is fixed. As time goes on, the number of follicles in the ovary will gradually decrease, thus gradually reducing the fertility of women. However, the follicles are not fully mature and discharged from the ovary, and some immature follicles remain after menopause.
