टेस्ट ट्यूब बेबी में हार्ट बीट क्यो चली जाती है?
Pregnancy loss can occur because of numerical chromosome abnormalities arising fro meiotic nondisjunction (eg, trisomy or monosomy), aberrant fertilization or embryogenesis or structural chromosomal abnormalities arising from inheritance of a derivative chromosomes.
An early cytogenetic study of 1500 miscarriage specimens reported that more than
61% of samples contained an abnormal karyotype.. Most human aneuploidies are maternally derived and increase as a function of
"Female age"..Only 7% of fetal trisomies arise from "Paternal meiotic errors".

PGT-A( also known as PGS or Pre impalntation Screening for Aneuploidy) with
selection and transfer of a euploid embryo has been shown to significantly decrease
risk of recurrent miscarriage. But with comparison to EM(expectant management)
PGT-A may reduce the miscaariage but not live birth rate.High quality data is still
lacking and is more costly per live birth.
All existing methods of PGS and diagnosis have an error rate and the risk of transferring
abmormal embryo must be balanced against the risk of discarding normal embryos.
Trophoectoderm mosaicism is another area of difficulty in choosing the best embryo after PGS.
At higher age women IVF-ICSI may not result in good blastocyst to be chosen or one or two blast...the dilemma is...should we put these/this blast to undergo this procedure (PGS...Still not proven well) or go for EM(expectant management). We choose the later at present. Source: Reproductive Genetics.. Obstetrics and Gynecology clinics of North America. March 2018
