Development of embryoses up to blastocystes-stages

[Nataschaa]

Dear Boris Aleksandrovich!



You could not express the opinion in a following occasion: 6- iksi-ON?a to sozh a negative, a fertilization 12 of 14, for the third day 8 better qualities of embryoses (7-8 klet, without fragments), on 5- put only one blostotsist (early), the others - morulas.



What could stop development of embryoses - bad medium (I vychitaa that for 4-th day change medium for kultivirovanija), bad genetics???



I wish to note still, that one year ago at us after iksi-ON?a was: a fertilization 7 of 15, for 5-th day 2 first-rate qualities of a blastocyste, rez-O pregnancy but extrauterine ---that is cells at us can (or could) to develop normally...



Thanks!

Natasha

That could stop development of embryoses - bad medium (I vychitaa that for 4-th day change medium for kultivirovanija),

To exclude it is impossible, but not in six attempts successively.



Bad genetics???

More often here again, probably, it is necessary to speak about carrying out doimplantatsionnoj diagnostics of embryoses.
