What is the prevalence of Fragile X - associated primary ovarian insufficiency (FXPOI)?

FXPOI occurs in about 20-25% of adult female FMR1 premutation carriers. It has also been reported in teenagers who are carriers, though it is less common in that population. 

About 2% (1 in 50) of women with ovarian insufficiency are found to have an FMR1 premutation, as do about 7% (1 in 15) of those with a personal and family history of ovarian insufficiency.
