The Transition From Blastomere to Trophectoderm Biopsy: Comparing Two PGS Strategies

Shortly after the implementation of Comprehensive Chromosome Screening (CCS) techniques for Preimplantation Genetic Screening (PGS) came the transition in biopsy timing. Trophectoderm biop...

A Study of Preimplantation Genetic Screening With Next Generation Sequencing Technology on Advanced Age Women

With the development of society, more and more aged pregnant women because of various reasons, their abnormality rate of egg chromosome was higher than that of young women, then the abnorm...

Prenatal Screening, Diagnosis and Intrauterine Intervention of Fetal Abnormal Chromosome and Structure in Twins Pregnancy

The risk of abnormal chromosome and structure is much higher in twins than in singletons, and traditional early pregnancy screening strategy for single pregnancy is not suitable for twins....

The eXtroardinarY Babies Study: Natural History of Health and Neurodevelopment in Infants and Young Children With Sex Chromosome Trisomy

This study is designed to research the natural history of neurodevelopment, health and early hormonal function in infants with XXY/Klinefelter syndrome, XYY, XXX and other sex chromosome v...

Impact of Parental Support on Pregnancy Outcomes (IPSO) Trial- Day 3 Preimplantation Genetic Screening (PGS) With Day 5 Fresh Transfer

Male infertility associated with de novo pericentric inversion of chromosome 1.

Inversion occurs after two breaks in a chromosome have happened and the segment rotates 180° before reinserting. Inversion carriers have produced abnormal gametes if there is an odd number crossing- ...

Comprehensive genetic testing for female and male infertility using next-generation sequencing.

To develop a comprehensive genetic test for female and male infertility in support of medical decisions during assisted reproductive technology (ART) protocols.

Detection of fetal subchromosomal aberration with cell-free DNA screening led to diagnosis of parental translocation: Review of 11344 consecutive cases in a university hospital.

Fetal chromosome aberrations and sub-chromosomal copy number variations (CNVs) are not rare. There are several ways to detect duplications and deletions; cell-free DNA screening (cfDNA screening) is n...

Clinical feature of infertile men carrying balanced translocations involving chromosome 10: Case series and a review of the literature.

Infertile male carrying balanced translocations can be broadly divided into two types: pregestational and gestational infertility. Chromosome and breakpoints involved translocation should be considere...

An economic analysis of chromosome testing in couples with children who have structural chromosome abnormalities.

Structural chromosome abnormalities can cause significant negative reproductive outcomes as they typically result in morbidity and mortality of newborns. The prevalence of structural chromosomal abnor...

Medical and Biotech [MESH] Definitions

The identification of selected parameters in newborn infants by various tests, examinations, or other procedures. Screening may be performed by clinical or laboratory measures. A screening test is designed to sort out healthy neonates (INFANT, NEWBORN) from those not well, but the screening test is not intended as a diagnostic device, rather instead as epidemiologic.

A form of male HYPOGONADISM, characterized by the presence of an extra X CHROMOSOME, small TESTES, seminiferous tubule dysgenesis, elevated levels of GONADOTROPINS, low serum TESTOSTERONE, underdeveloped secondary sex characteristics, and male infertility (INFERTILITY, MALE). Patients tend to have long legs and a slim, tall stature. GYNECOMASTIA is present in many of the patients. The classic form has the karyotype 47,XXY. Several karyotype variants include 48,XXYY; 48,XXXY; 49,XXXXY, and mosaic patterns ( 46,XY/47,XXY; 47,XXY/48,XXXY, etc.).

Inability to reproduce after a specified period of unprotected intercourse. Reproductive sterility is permanent infertility.

Clinical conditions caused by an abnormal sex chromosome constitution (SEX CHROMOSOME ABERRATIONS) in which there is extra or missing sex chromosome material (either a whole chromosome or a chromosome segment).

Clinical conditions caused by an abnormal chromosome constitution in which there is extra or missing chromosome material (either a whole chromosome or a chromosome segment). (from Thompson et al., Genetics in Medicine, 5th ed, p429)
