  Causes and Risk Factors 
 A woman is born with a finite number 
                                              of eggs that are stored in the ovaries. 
                                              The hormones that regulate menstruation 
                                              and ovulation (estrogen and progesterone) 
                                              are also stored in the ovaries. 
                                              Menopause occurs when the ovaries 
                                              cease to produce an egg every month, 
                                              resulting in the permanent ending 
                                              of menstruation.
 Menopause 
                                                typically occurs after the age 
                                                of 40 years (typically in the 
                                                range of 40-55 years) and is considered 
                                                to be a normal part of aging. 
                                                However in some cases, premature 
                                                menopause occurs as a result of 
                                                surgery such as hysterectomy or 
                                                damage to the ovaries because 
                                                of chemotherapy. Menopause that 
                                                occurs before the age of 40 years 
                                                is called premature menopause.

                                                can affect the physical and emotional 
                                                health of women. It is believed 
                                                to cause bone disorders like osteoporosis 
                                                as well as breast cancer and certain
