Testicular expression of TDRD1, TDRD5, TDRD9 and TDRD12 in azoospermia. [PDF]

, 2020
BACKGROUND: Tudor domain-containing proteins (TDRDs) play a critical role in piRNA biogenesis and germ cell development. piRNAs, small regulatory RNAs, act by silencing of transposons during germline development and it has recently been shown in animal ...

Investigating developmental characteristics of biopsied blastocysts stratified by mitochondrial copy numbers using time-lapse monitoring

Reproductive Biology and Endocrinology
Background For in vitro fertilization (IVF), mitochondrial DNA (mtDNA) levels in the trophectodermal (TE) cells of biopsied blastocysts have been suggested to be associated with the cells’ developmental potential. However, scholars have reached differing

Extended blastocyst culture improves DNA yield in non-invasive preimplantation genetic testing for aneuploidy but diagnostic specificity remains limited

Scientific Reports
Non-invasive preimplantation genetic testing for aneuploidy (niPGT-A), which analyzes cell-free DNA (cfDNA) from spent culture media (SCM), has emerged as a proposed alternative to trophectoderm (TE) biopsy in in vitro fertilization (IVF).
