All women are born with a certain number of eggs and therefore it is not possible to increase the ovarian reserve. However, it is possible to maintain the highest possible ovarian reserve for longer by maintaining a healthy lifestyle (maintaining a healthy weight, avoiding smoking, limiting alcohol consumption and exercising regularly) and taking certain supplements such as folic acid and antioxidants such as vitamin E and selenium. In addition, with the right fertility treatment, a woman's ovarian response can be improved to obtain a greater number of mature eggs in a single menstrual cycle.
