Study Question: Can independent predictors of pregnancy-associated plasma protein-A (PAPP-A) levels be identified in a group of women who conceived following IVF/ICSI?
Summary Answer: The significantly decreased PAPP-A level in IVF and ICSI pregnancies compared with non-IVF/ICSI pregnancies was correlated strongly with the serum estradiol (E2) level at ovulation triggering.
What Is Known Already: The first trimester prenatal combined screening test for fetal aneuploidies in pregnancies conceived following assisted reproduction techniques (ART) is complicated by an alteration of the maternal biomarkers free β-hCG and PAPP-A, causing a higher false-positive rate compared with pregnancies which are conceived naturally. The use of controlled ovarian stimulation prior to IVF/ICSI is suggested to be the principle reason for these alterations of biomarkers in ART pregnancies.
Background: The high frequency of the cystic fibrosis (CF) transmembrane conductance regulator (CFTR) gene mutation p.Arg117His in patients with congenital bilateral absence of the vas deferens (CBAVD) and in newborns screened for CF has created a dilemma.
Methods: Phenotypic and genotypic data were retrospectively collected in 179 non-newborn French individuals carrying p.
Innovative biotechnical progress over the past few years regards stem cells and therapeutic cloning, which open promising medical horizons for many presently incurable diseases. THE CURRENT DEBATE: The research work in France has been stalled because of the prohibitions listed in the so-called "bioethical" laws of 1994. The ongoing revision of these laws is based on a certain number of ethical questions and launches a disputable parlementary debate.
