[Olga]

Prompt please why even at IKSI not all ootids are impregnated or fertilized? And whether the impregnated ootids and why can to cease to share?

[Kamenetskij B.A.]

Yes, even at carrying out IKSI not all cells can really be impregnated, and the part from them will stop in development. A principal cause is quality of ootids. Unfortunately, to estimate or appreciate quality of the received ootids difficultly enough. At carrying out doimplantatsionnoj diagnostics of these embryoses, as a rule, are found out chromosomal anomalies.
