Premature ovarian failure occurs when the ovaries stop releasing eggs before the age of 40. Menopause-like symptoms include irregular or no periods, infertility, hot flashes, and vaginal dryness. Causes of premature ovarian failure may be genetic, an autoimmune response, or a result of cancer radiation therapy. Treatment may include hormone therapy. It is difficult, but not impossible, to become pregnant with the condition.
