Premature menopause was a term used to describe premature ovarian failure in the past. However, this term does not accurately describe what happens to women who experience POF. One of the big differences is that a woman who has experienced natural menopause, in most cases, will never have another period: while, a woman who experiences premature ovarian failure has a good chance of future periods even if they are irregular or abnormal in some way. Another important difference is the fact that a woman who experiences natural or surgical menopause has no chance of becoming pregnant, while women with premature ovarian failure still has a chance of conceiving.
