Ovarian function decline refers to the weakening of the ovaries’ ability to produce eggs, i.e., a decrease in the number and quality of eggs, which in turn leads to a decrease in fertility and lack of sex hormones, manifesting as sparse menstruation, reduced menstrual flow, or even amenorrhea, and reduced fertility. In order to delay the decline of ovarian function, you can eat more beans, wheat, black rice and other foods rich in phytoestrogens. It is recommended to eat more vegetables and fruits, which can be supplemented with vitamins, and to do proper sports. Chinese herbal medicine has its irreplaceable role in improving the decline of ovarian function.
