For most women, natural menopause occurs between the ages of 45 and 55, with the average age of onset being 51.4 years of age. In rare instances, menopause can occur as early as the 30's or as late as the 60's. Perimenopause and some symptoms associated with it normally start in the age of 40's and early 50's, although it's very possible to experience perimenopause in your early 30's. Pre menopause age or premenopause age - most women begin to experience some type of gradual slowdown of their reproductive cycle resulting in premenopause symptoms and health issues somewhere between their early 30's to their 40's.
