Normally, menopause begins around the age of 50. Premature ovarian failure can cause the ovaries to stop functioning normally before 40. This condition occurs when the ovaries stop releasing eggs regularly or fail to produce normal amounts of estrogen.
A variety of factors can cause early menopause, but the cause is usually not discovered. Often, there is a family history of the condition. About 10-20% of women experiencing this condition will find it in their family history. Certain medical conditions, such as thyroid disease or surgical removal of the ovaries, can also cause early menopause. Radiation or chemotherapy can also cause this condition.
