What is the reproductive status of the patient?
Reproductive age and Early menopausal
Notes:
Patients are classified as reproductive age female or postmenopausal. If the menopausal status is unknown, some authors suggest 50 years of age can be used as an arbitrary designation for the age of menopause. A patient up to 50 years of age is considered as reproductive age. A patient >=50 years of age is considered postmenopausal. Physiologically, the postmenopausal period can be divided into two stages: Early postmenopause (within 5 years of the final menstrual period or ages 50-55 if menopausal status unknown) and Late postmenopause (>5 years from the final menstrual period or age >55 years if menopausal status unknown).
