I am 32 years old and i have not had a period in a year or more my doctor said i had dysplasia on my cervix could this be why don't have a cycle?

Maybe but not likely: If a person had severe dysplasia that was causing a blockage in the cervix to prevent the release of menstrual blood that might prevent a cycle but would be very rare. Most of the time absence of menses is a hormone imbalance. In general these are two separate problems.

No: Dysplasia is not a cause of lack of periods. You may wish to visit this site for info: http://www.nichd.nih.gov/health/topics/menstruation/conditioninfo/Pages/causes.aspx
