Pregnancy and reproductive function in a patient with non-mosaic Turner syndrome.

: A patient with non-mosaic Turner syndrome and normal fertility had four documented pregnancies, two of which were carried to term. Although her fertility history can be considered normal, she did not have spontaneous sexual maturation or menarche, and bilateral streak gonads were identified on laparotomy for tubal ligation. A review of the literature on non-mosaic Turner syndrome and reproductive function indicates that there are several theories to account for the extreme variety of ovarian function in such patients, but not enough data are yet available to form a conclusion.
