Repeated measures correlation (rmcorr) is a statistical technique for determining the common within-individual association for paired measures assessed on two or more occasions for multiple individuals. Simple regression/correlation is often applied to non-independent observations or aggregated data; this may produce biased, specious results due to violation of independence and/or differing pat...

By selecting chromosomally normal embryos for replacement, PGD for aneuploidy can (i) increase implantation rates, (ii) reduce spontaneous abortion rates, and (iii) avoid aneuploid conceptions. When eight chromosomes are analysed, a significant increase in implantation is achieved. PGD is also found to significantly reduce the incidence of spontaneous abortion and chromosomally abnormal concept...

Aneuploidy in pregnancy is known to increase with advanced maternal age (AMA) and associate with repeated implantation failure (RIF), and repeated miscarriage (RM). Preimplantation genetic screening (PGS) has been introduced into clinical practice, screening, and eliminating aneuploidy embryos, which can improve the chance of conceptions for infertility cases with poor prognosis. These patients...
