The pressure of social competition and the increasing cost of living make women give birth later and later, and age is one of the important factors affecting fertility. Older women face many problems in fertility, such as declining ovarian function, lower egg quality, poor intrauterine environment, pelvic inflammatory disease, or other physical diseases, etc., resulting in a much lower natural conception rate than younger women. How can older women maintain the quality of their eggs when preparing for pregnancy? First, you should change your lifestyle habits. It is important to have a good sleep and a regular routine. The ovaries are part of the endocrine system, and they can also become dysfunctional, affecting the maturation of eggs and ovulation, which can manifest as menstrual disorders, spots or acne on the face, mood swings, etc. Secondly, a healthy diet and a happy mood, a reasonable diet will help balance and regulate the hormones in a woman’s body, allowing the ovaries to fully play their role normally. The reason is that the precursor of estrogen is cholesterol, and a long-term vegetarian diet will cause insufficient secretion of estrogen and lead to the decline of ovarian function. Excessive stress can affect the neuroendocrine system and cause menstrual disorders and infertility. In addition, certain medications can affect ovarian function. For example, emergency contraceptive pills or irregular use of oral contraceptive pills. Emergency contraceptives are anti-progestational or strong progestational agents that can disrupt the normal endocrine function of the ovaries if used repeatedly; oral contraceptives can lead to the same result if taken without medical advice. There are also drugs used to treat breast cancer that have an effect on ovarian function. There is also the avoidance of ovarian surgery. Ovarian surgeries such as ovarian perforation, ovarian chocolate cyst debulking, ovarian teratoma removal, etc. not only remove some ovarian tissue but also affect the blood supply to the ovaries. Therefore, for women with fertility requirements, ovarian surgery is not recommended as a last resort.
