The ovaries themselves can basically be considered to have no fertility function at the age of 48. But there are many ways to do this now. For example, the so-called ovarian maintenance. So far there is no method to say so. It may still be a lifestyle attitude. If you eat irregularly and take some supplements, you can still keep your body in relatively good condition. There is no rejuvenation technique, but still do what you need to do when you need to do it.
