The purpose of our study was to assess the influence of intra-uterine insemination (IUI) on the results of maternal serum Down syndrome screening. 43 women with IUI pregnancies and 4507 healthy women who conceived were studied. Ovulation in IUI pregnancies was induced by clomiphene and/or human meno

β¦ Synopsis
To assess the influence of in vitro fertilization (IVF) on maternal serum human chorionic gonadotrophin (hCG) and alpha-fetoprotein (AFP), the maternal serum hCG and AFP values were studied in 67 IVF pregnancies and compared with the results of a control group of 4732 spontaneously conceiving patients. Maternal serum hCG was significantly higher and AFP significantly lower in the IVF group, Possible explanations and implications for prenatal diagnosis in IVF pregnancies are discussed.

A nested case-control study using stored serum samples collected as part of a prospective study of the outcome of pregnancy was performed to investigate concentrations of (dimeric) inhibin-A in maternal serum between 15 and 22 weeks of pregnancy in 200 twin pregnancies and 600 singleton control preg
Case-control studies in the Caucasian population showed that maternal serum inhibin-A is elevated in Down syndrome pregnancies and may be a useful second-trimester marker in addition to human chorionic gonadotrophin (hCG) and alpha-fetoprotein (AFP). Data in the Asian population are lacking. We meas
Protein S100 is a low molecular weight (10-12 kD) calcium-binding protein the beta subunit of which is coded for at the 22.2-22.3 region of the long arm of chromosome 21. This region has also been shown to be responsible for the phenotypic expression of Down syndrome. Previous studies demonstrated i
