Go thru this excerp from emedicine article
"Causes: In the first trimester, embryonic causes of spontaneous abortion are the predominant etiology and account for 80-90% of miscarriages. Genetic abnormalities within the embryo (ie, chromosomal abnormalities) are the most common cause of spontaneous abortion and account for 50-65% of all miscarriages. The most common single chromosomal anomaly is 45,X karyotype, with an incidence of 14.6%. Trisomies are the single largest group of chromosomal anomalies and account for approximately one half of all anomalies associated with miscarriage. Trisomy 16 is the most common trisomy found. Approximately 20% of genetic abnormalities are triploidies" http://www.emedicine.com/med/topic3310.htm what shud be now inferred of this?? thanx |
