Most-that is up to 99%(11)-of all embryos or fetuses with Turner's syndrome are spontaneously miscarried during the first and second Tiffany Notes of pregnancy. Although monosomy X is not associated with older mothers, the use of prenatal karyotype analysis (by means of chorionic villi sampling or amniocentesis) has led to the identification of an increasing number of Tiffany Necklaces syndrome pregnancies.

In addition, regular ultrasound examinations have aided the detection of nuchal cystic hygroma and non-immune hydrops Tiffany Money Clips pregnancy, which are typical but not pathognomonic of Turner's syndrome. If the degree of nuchal translucency exceeds Tiffany Keys normal range in fetuses, the risk of aneuploidy is higher. Coarctation of the aorta, renal anomalies, and growth retardation are further ultrasound findings typical for Turner's syndrome.

In addition, several markers in maternal serum are associated with aneuploid pregnancies, including Turner's syndrome, and Tiffany Key Rings increased concentrations of alpha fetoprotein, human chorionic gonadotropin, unconjugated oestriol, and inhibin A.12 The positive or negative predictive value of biochemical markers and sonography, however, is not Tiffany Sets high. The correlation between prenatal karyotyping for elucidation of data on the Turner's syndrome phenotype and its severity is rather weak. This is particularly true in cases with mosaicism.
