The ovarian reserve refers to the capacity of your ovaries to produce healthy, viable eggs. The ovarian reserve and the quality of available eggs naturally begins to decrease after the age of 35 though eggs are still produced up until menopause.
Symptoms of an impending menopause include hot flashes, irregular periods, night sweats, irritability, difficulty concentrating or decreased sexual drive. Though a diminishing ovarian reserve is something that occurs naturally as women age, external factors like environmental toxins and lifestyle choices can also play a role.
