Role of comprehensive cytogenomic investigation in successful reproductive outcome of parental small neocentromeric supernumerary ring chromosome: A case report

Clinical Case Reports, 2023
Small supernumerary marker chromosomes (sSMC) can form small supernumerary ring chromosomes (sSRC). Loss of parentally inherited sSRC containing vital gene content may cause an “unbalanced” karyotype and fetal microdeletion syndromes.

Advanced Paternal Age Impacts Common Loci in the Sperm and Placenta DNA Methylomes

Andrology, EarlyView.
ABSTRACT Background Epidemiological studies have reported an association between advanced paternal age at conception and an increased risk of neurodevelopmental disorders in offspring, such as autism spectrum disorder. Evidence suggests that DNA methylation alterations in spermatozoa of older men may be transmitted to the feto‐placental unit and ...

Impact of double versus single blastocyst biopsy and vitrification on clinical and neonatal outcomes in PGT cycles: A systematic review and meta‐analysis of embryo retesting

Acta Obstetricia et Gynecologica Scandinavica, EarlyView.
Rebiopsied and revitrified blastocysts may be linked to lower pregnancy and live birth rates in single euploid frozen embryo transfer cycles (very low‐quality evidence). Subgroup effects by biopsy day and morphology may hold clinical relevance and guide future study design.
