Diminishing ovarian reserve is another cause of infertility among women. Ovarian reserve refers to the capacity of a woman’s ovaries to produce healthy and viable eggs. Although eggs are still produced until menopause, the ovarian reserve and the quality of available eggs naturally begins to decrease after the age of 35.

Symptoms of an impending menopause include hot flashes, irregular periods, night sweats, irritability, and difficulty concentrating or decreased sexual drive. Though a diminishing ovarian reserve is something that occurs naturally as women age, external factors such as environmental toxins and lifestyle choices can also play a role in impacting the ovarian reserve in women.
