An Effective Method for Detecting Y-chromosome Specific Sequences of Circulating Fetal DNA in Maternal Plasma During the First-trimester

Background and Aims: New advances in the use of cell-free fetal DNA (cffDNA) in maternal plasma of pregnant women has provided the possibility of applying cffDNA in prenatal diagnosis as a non-invasive method. One of the applications of prenatal diagnosis is fetal gender determination. Early prenatal determination of fetal sex is required for pregnant women at risk of X-linked and some endocrin...

Prenatal sex determination in suspicious cases of X-linked recessive diseases by the amelogenin gene

Objective(s):To determine the fetal discernment in suspected cases of sex linked recessive disease in the first trimester of pregnancy. Materials and Methods: After collection of 100 Chorionic Villi samples, the DNAs were extracted and baby gender was determined. Meanwhile, after increasing the sensitivity, the system was able to detect the sex of each cell which was obtained by biopsy. Resul...

Son Preference and Early Childhood Investments in China⇤

Child sex may have become a stronger signal of parental sex preferences over time as the cost of sex selection has declined and sex ratios at birth have increased. In this paper, we build on Chen, Li and Meng’s 201...
