Overview
Causes
The cause of POF is usually idiopathic. Some cases of POF are attributed to autoimmune disorders, others to genetic disorders such as Turner syndrome and Fragile X syndrome. In many cases, the cause cannot be determined. Chemotherapy and radiation treatments for cancer can sometimes cause ovarian failure. In natural menopause, the ovaries usually continue to produce low levels of hormones, but in chemotherapy or radiation-induced POF, the ovaries will often cease all functioning and hormone levels will be similar to those of a woman whose ovaries have been removed. Women who have had their tubes tied, or who have had hysterectomies, tend to go through menopause several years earlier than average, likely due to decreased blood flow to the ovaries.
In many cases, the cause of premature ovarian failure is not clear. Some studies demonstrate that the following factors may be involved in the cause of this disorder.
- Chromosomal defects: Studies demonstrate that certain genetic disorders may be associated with premature ovarian failure, such as Turner's syndrome and fragile X syndrome.
- Toxins: Toxins, such as chemotherapy, radiation therapy, cigarette smoke, chemicals, pesticides and viruses may damage the genetic material in cells and hasten ovarian failure.
- Autoimmune diseases: Autoimmune diseases may cause follicle dysfunction, which may produce antibodies against her own ovarian tissue and harm the egg-containing follicles, then result in premature ovarian failure.
- Age: The risk of ovarian failure rises as you age.
- Genentic factors: Having a family history of premature ovarian failure increases your risk of developing this disorder.
