Francesca, da li si ti baš tražila da ti vrati 5. dp, jer možda da ti je vratio 3. dan bi ih bilo više? Ipak su im veće šanse da se uspješnije razvijaju u prirodnom okruženju.

Htjela bi se nadovezati na ovo gore, što više čitam o tome nalazim da to i nije baš tako. Stavit ću ovdje link na zanimljivu prepisku s embriologom na jednom američkom forumu koji tvrdi da:
Dr Smith replies:
The primary reason embryos do not make it to the blastocyst stage is because they do not possess the necessary genetic instructions for continued growth. No one can change or improve the genetics of an embryo. Assuming the lab is competent (and most are), there is no "risk" associated with continuing to culture the embryos to the blastocyst stage. I think you're making the false assumption that the embryos are better off in your uterus on day 3. They're not. Under natural conditions, the embryo remains in the Fallopian tube until the fifth day of development (blastocyst stage). The uterine environment on day 3 is not the same as the Fallopian tubes. When sequential culture systems are employed to grow the embryos to the blastocyst stage, the conditions in the laboratory more closely resemble the Fallopian tubes. Therefore, the embryos are better off in the lab for day 4-5 of development.
The point of growing embryos to the blastocyst stage in the laboratory is to deliberately weed out the embryos that do not have the genetic potential for continued growth. The "risk" you speak of doesn't really exist. If they're gonna make it, they do. If they don't, they don't. Of course, there's always the "risk" that no embryos make it to the blastocyst stage in the laboratory, but (because the problem is related to the genetics of the embryo, not culture conditions in the laboratory) they wouldn't have made in the uterus either.
I hope this clears things up. Good luck. I hope things work out for you.
Meni je ovo bilo vrlo zanimljivo, ovdje je link na cijeli razgovr:

Od svih Rešovki ja sam (što se dana transfera tiče) najlošije prošla, dobili smo 3 js. i dr, me je na punkciji pitao kada želim doći na transfer, ja sam naravno rekla 5-dan, na što se on naravno nasmijao i rekao da to nije moguće s tako malo stanica( da bi ih trebalo biti puuuno više) i rekao mi je da dođem drugi dan ( znala sam da ni to nije dobro), kao da je znao... oplodila nam se samo jedna js. i valjda se bojao da neće izdržati ni do trećeg dana... iako je na kraju to bio već drugi dan pravilan četverostanični embrij bez fragmentacija.
