Is it possible to go through menopause at age 26 if you only have one ovary?

Just because you have one ovary, does not mean the time period that your body deems necessary for carrying children shortens. Although rare, early menopause is possible and has many causes. Severe medications, and drugs used for cancer treatment such as chemotherapy have been known to be a factor in early menopause. Regardless of the cause, if you haven't had a period for more than three months your best bet is to check it out with your gyno.
