Signs & Symptoms
Common symptoms of FXPOI (ovarian insufficiency) include absent or irregular cycles, “sub-fertility” or infertility, hot flashes, and premature ovarian failure (POF), which is the complete cessation of menstrual periods before the age of 40. In the wider range of FXPOI symptoms, premature ovarian failure is at the more severe end of the spectrum.
FMR1 premutation carriers can have normal ovarian function, but can still go through early menopause, which is menopause occurring between 40 and 45 years of age (menopause normally occurs between 45 and 55 years old).
Even though women with FXPOI may develop symptoms similar to those of menopause, such as hot flashes and vaginal dryness, FXPOI differs from menopause in some important ways:
|Women with FXPOI
|Women who have completed menopause
|Can still get pregnant in some cases because their ovaries may occasionally function to release viable eggs.
|Cannot get pregnant because their ovaries no longer release eggs.
|Can experience a return of menstrual periods.
|Cannot have menstrual periods again.
How do you know if you have FXPOI? By definition, all women who have FXPOI have an FMR1 premutation. If you are experiencing FXPOI symptoms and haven’t been tested you should arrange with your physician to have FMR1 genetic testing.
The American Society for Reproductive Medicine and American College of Obstetrics and Gynecology recommend that all women with ovarian insufficiency or elevated FSH (a hormone that reflects ovarian function) levels have FMR1 testing. Any physician or genetic counselor can order testing for Fragile X.
If you can’t find a genetic counselor in your area call us at (800) 688-8765 or visit the National Society of Genetic Counselors.
If you have already been tested and are a confirmed FMR1 premutation carrier, you should alert your physician to the risk of FXPOI in carriers (some physicians might not be aware of this condition).
All female FMR1 carriers should keep a log of their menstrual cycles and note any unusual patterns, missed cycles, abnormally long cycles (more than 35 days), or short cycles (less than 21 days). Also note any other physical changes such as hot flashes, insomnia, vaginal dryness and/or decreased libido, increased anxiety, etc.
If you are concerned that you might have FXPOI, talk to your physician about having your FSH, a hormone that reflects ovarian function, measured. FSH levels increase as you approach menopause or if your ovaries are not functioning properly for your age.
Treatment & Intervention
Many women who are FMR1 premutation carriers can get pregnant. However, all carriers are at risk to have children with FXS so should meet with a genetic counselor to discuss reproductive issues.
Some carriers are initially identified because they have fertility problems and are considering fertility treatment.
If you conceive naturally, you have the option of prenatal testing through amniocentesis or chorionic villus sampling (CVS) to evaluate the genetic status of your pregnancy.
If you do not have normal fertility, you can discuss various assisted reproductive options with your reproductive endocrinologist, including IVF with your own eggs, IVF with eggs donated by a non-carrier, attempting to get pregnant naturally, or adoption.
