J2 or J3 transfer in IVF / ICSI

When IVF provides many embryos, it is legitimate to expect J3 before relocating to select the best, or to push the culture of blastocysts to transfer the highest quality.

But if the embryos are few and do not warrant a selection, a study in “Fertility & Sterility” May states that the transfer to J2 regardless of embryo quality increases the chances of pregnancy in women under 40 years.

It establishes and “the date of transfer is a significant predictor of clinical outcome in cases where a small number of embryos available for transfer. Evidence suggests that limiting embryo culture only 2 days reduces the miscarriage and increases the pregnancy rate continued.”

This study echoes another issued in 2004 which had focused on the results of 2027 women. It was shown that transfer to D3 increased the clinical pregnancy rate in ICSI cycles but that the rate of miscarriage is not possible to increase correspondingly the rate of live births.

  1. Interesting this article, but reimplantation j2 or j3 for a woman over 40 years, is it really interesting?? My center offers no alternative but IVF ICSI j2 or j3, already after 3 chess, I doubt that the Fiv 4 can function…

    • This is an option to discuss with your doctor.
      One of mine was the transfer of nuclei pro, confirmed after fertilization and before the first division (11h after puncture…)
      My other gyno does not believe.
      And I have a copinante who had her babies yet and while it did not work before.
      All that to say that it is important to contact your doctor to make this last attempt confidence…
      And an attempt, it can also prepare ! With the supply, healthy living… A fortiori the last.
      Courage ! Your doctor believes !
