When we are a fetus, at 16-20 weeks in our mother’s womb, we have 6-7 million germ cells in our ovaries bilaterally; at birth there are about 2 million left, and by puberty there are only about 300,000 left. However, only 400-500 follicles develop and ovulate during a woman’s lifetime, accounting for only 0.1% of the total. With the development of social civilization, changes in living environment and lifestyle, and increased mental stress, more and more women are experiencing early menopause and even premature ovarian failure. Premature ovarian failure refers to the failure of ovarian function before the age of 40. When they finally stop their career struggle and want to become a mother, their chances and hopes become slim and to have a healthy and lovely baby so unattainable. The literature reports that women over 35 years of age have a much lower natural pregnancy rate, mainly due to their low ovarian function, irregular ovulation and a significant decrease in egg quality. Because the probability of chromosomal abnormalities in eggs increases with age, older women are not only less likely to become pregnant, but are also more likely to have embryonic abnormalities in the fetus after pregnancy. With such an important function of the ovaries, how can we protect women’s ovarian function? First of all, you should change your lifestyle habits. Good sleep and rest are very important. If a woman stays up late for a long time, her endocrine secretion will be disturbed, manifested by menstrual disorders, spots or acne on her face, mood swings, etc. The ovaries are supposed to be a gland that secretes hormones, and with endocrine disorders, the ovaries can also experience disruptions in secretion. Likewise, a healthy diet and a happy mood will help balance and regulate the hormones in a woman’s body, allowing the ovaries to play their role fully and normally. Excessive stress can also affect the neuroendocrine system, causing menstrual disorders that make it difficult to get pregnant, and also cause premature ovarian decline. Second, certain medications can affect ovarian function. Such as emergency contraceptives or irregular use of short-acting oral contraceptives. Emergency contraceptives are anti-progestational or strong progestational agents, which can disrupt the normal endocrine function of the ovaries if used repeatedly; short-acting oral contraceptives can lead to the same result if taken randomly without medical advice. There are also drugs used to treat breast cancer that have an effect on ovarian function. Again, avoid ovarian surgery. Ovarian surgery such as ovarian perforation, ovarian chocolate cyst removal, ovarian teratoma removal, etc. not only removes some ovarian tissue, but also affects the blood supply to the ovaries. Therefore, for women with fertility requirements, do not rush to undergo ovarian surgery as a last resort. Finally, it is important to have children at an appropriate age and avoid having children at an advanced age. On the one hand, having a baby when a woman’s ovaries are functioning optimally is good for both mother and baby. The mother’s body is in the best condition, the eggs are of the best quality, and the baby can be physically and mentally sound. On the other hand, it is a reflection and preservation of the value of the reproductive function of a woman’s ovaries, and the offspring receive healthy genes. When a woman carries her baby for ten months, she has ten fewer periods and ten fewer eggs, and her menopause is delayed backwards. It is important to protect ovarian function before it is too late. Don’t wait until you are older and your ovarian function is already low before you regret it. As long as you have healthy ovaries, you will be naturally feminine and will no longer need all kinds of cosmetics to look beautiful. Assisted reproductive technology (ART) plays an irreplaceable role in the treatment of infertility for women of advanced age with fertility needs, and has made millions of families successful and happy. Especially for women of advanced age with fertility requirements, ART is an irreplaceable role.
