From the beginning of development in the ignorant teenage years, to the subsequent maturation, aging and loss of function of the ovaries!
Just a few dozen words, but the female friend's previous decades of years and ups and downs!

Yes, the ovaries function differently from other organs, and their role is not lifelong. Under normal circumstances, women in the 12-15 years of age, affected by the development of secondary sexual characteristics, the ovaries gradually have ovulation and endocrine functions, such as the first female menstrual period, in fact, is a major manifestation of the beginning of ovarian development.
After that, as women continue to age, the ovaries will gradually mature, forming a unique ovulation cycle and regularity.
However, ovarian function only lasts until the age of 45-55 in women, and once the follicles in the ovaries are exhausted, or if the follicles can no longer respond to gonadotropins, they can no longer release eggs and produce hormones.
The endometrium does not perceive hormonal changes, naturally can not carry out metabolism, when the ovarian function is completely reduced, menstruation will stop.
The process from the beginning of the decline of gonadal function to the complete loss is actually what is clinically called the perimenopause period, which is commonly known as menopause. Women in our country are affected by genes, physique and environment, and most of them have menopause before the age of 50.
Many people mistakenly believe that menopause has a very large impact on women, accelerating aging, making the skin condition worse and worse, affecting personality, and so on.
But in fact, everyone has reversed one thing, menopause is not to accelerate aging, it is actually one of the symptoms of aging, it is precisely because of the decline of ovarian function, which caused the emergence of menopause. Even if there is no menopause at this age, wrinkles, gray hair, in fact, it has already quietly found you!
Moreover, even if the ovaries lose function, the adrenal glands will in fact produce the right amount of estrogen, which will not affect women's health. Scientifically, menopause simply means that women lose their reproductive function. If menopause is forcibly intervened, or if you are over 60 years old and have not had menopause, this will not have any health benefits!
So the question is, after the late passage, will it have an impact on the body?
We must clearly understand that the laws of nature are irresistible to us, and no matter which woman, she will experience puberty and menopause. If a woman is over 60 years old, or even over 65 years old and still has no menopause, this is often a manifestation of abnormal ovarian function, which is likely to be ovarian granulocytoma and follicular membrane cell tumor in the body;
In addition, even if there is no tumor, women beyond the normal age and have not been menopausal, which means that there is still ovulation and hormone secretion in the body, which will cause stimulation to multiple organs such as the ovaries, endometrium, and breast, which may increase the chance of organ cancer. In particular, the ovaries are repeatedly ovulated, damaged and repaired, and may become cancerous in the future!
In the same way, if the age of menopause in women is too early, it may also be a signal of the arrival of diseases, such as women with polycystic ovary syndrome, premature ovarian failure, etc., which will cause the problem of premature menopause.
In a word, things and things in the world have their own laws, and human beings are also adhering to the laws formulated by nature to evolve, reproduce, and continue endlessly.
As a woman, entering adolescence is the age of menarche, and when it comes to menopause, you have to say goodbye to menstruation, which is a natural law, and learning to accept it calmly is the most important.
