    Description / Table of Contents: Summary Comparative genomic hybridization (CGH) is a molecular cytogenetic method for the detection of chromosomal imbalances between a tumor and a normal genome. In order to produce quantitative and reproducible results, we developed an image analysis program that allows the detection and mapping of the genetic alterations. The result is represented as a CGH sum karyogram in which the genetic changes are documented as color coded-chromosomes. The aim of our investigation is to correlate the genotype with the phenotype on the basis of CGH sum karyograms and thus to achieve a genetic characterization that will supplement the morphological tumor description.
    Notes: Zusammenfassung Die komparative genomische Hybridisierung („comparative genomic hybridization“, CGH) ist ein molekularzytogenetisches Verfahren, welches die umfassende Analyse eines Tumorgenoms auf Über- und Unterrepräsentationen von DNA-Abschnitten ermöglicht. Um quantitative und reproduzierbare Aussagen über die genetischen Aberrationen machen zu können, wurde eine Software entwickelt, welche die objektive Erfassung von Ort und Art der Veränderungen ermöglicht. Das Ergebnis wird in Form eines CGH-Summenkaryogramms dargestellt, welches die genetischen Veränderungen als farbkodierte Chromosomen dokumentiert. Ziel dieser Untersuchungen ist es, auf der Grundlage von Summen-Karyogrammen eine Korrelation zwischen Genotyp und Phänotyp herzustellen und damit eine genetische Charakterisierung von Tumoren zu erreichen, die die morphologische Beschreibung ergänzt.

    Notes: Abstract Purpose: We previously demonstrated that aneuploidy-free oocytes may be preselected by testing the first and second polar bodies removed from oocytes following their maturation and fertilization. The present paper describes the results of the application of the method in 659 in vitro fertilization cycles from patients of advanced maternal age. Methods: Using micromanipulation techniques, 3943 oocytes were tested by polar body sampling and fluorescent in situ hybridization analysis using specific probes for chromosomes 13, 18, and 21. Results: Fluorescent in situ hybridization results were available for 3217 (81.6%) of 3943 oocytes studied, of which 1388 (43.1%) had aneuploidies; 35.7% of the aneuploidies were of first meiotic division origin, and 26.1% of second meiotic division origin. Most errors in the first meiotic division were represented by chromatid malsegregation. The transfer of embryos deriving from 1558 of 1829 aneuploidy-free oocytes in 614 treatment cycles resulted in 131 clinical pregnancies and 88 healthy children born after confirmation of the polar body diagnosis. Conclusions: Polar body testing of oocytes provides an accurate and reliable approach for prevention of age-related aneuploidies in in vitro fertilization patients of advanced maternal age.
