  • As we further perfect our own techniques of vitrification, we will be increasingly more confident in our ability to offer young women with a viable option for future family planning in addition to embryo freezing and donor gametes. (pacificfertilitycenter.com)
Embryonic1
  • Mouse naive embryonic stem cells have recently been shown to give rise to embryonic and extra-embryonic stem cells capable of self-assembling into post-gastrulation structured stem-cell-based embryo models with spatially organized morphogenesis (called SEMs)3. (bvsalud.org)
Assessment1
  • In standard IVF, we would usually carry out this traditional assessment of embryos once a day, opening up the incubator and very carefully taking out the embryos to look at them under the microscope. (carefertility.com)
Retrospective1
  • A retrospective analysis of 698 FET cycles was performed to evaluate the value of culturing embryos to Day 7. (txfertility.com)
Normal5
  • By using PGS, we're able to identify genetically normal embryos and reduce miscarriages for patients. (carolinaconceptions.com)
  • It sounds like a great result and I will predict you will have at least 2-3 normal embryos. (reproductivepartners.com)
  • And earlier this week we got the PGT results for our second ER - both embryos sent for testing are normal! (whattoexpect.com)
  • The only normal embryo among the all-biopsied embryos had the highest "Mitoscore" value and was the only arrested embryo in both cases. (artfertilityclinics.com)
  • To this end, IVF-Life administers intravenous immunoglobulin, which helps reducing the NK levels - although Marie's immune response was within normal parameters, additional measures were taken to protect the patient's only embryo and her last chance to become a mother. (ivf-spain.com)
Mosaicism4
  • If you learn that some of your embryos have mosaicism, you might have questions about transferring mosaic embryos. (txfertility.com)
  • The report then ranks each euploid embryo for the level of embryo mosaicism. (txfertility.com)
  • Detecting mosaicism in embryos is an evolving science. (txfertility.com)
  • On day 3, one or two cells are removed, and around one third of the embryos are affected by mosaicism, influencing the diagnostic accuracy of the test. (medscape.com)
Oocyte1
  • The quality of the embryo is dependent on the quality of the oocyte that created it. (myivfanswers.com)
Vitrification2
  • Thanks to vitrification , the technology for embryo freezing has advanced tremendously since the days of slow freezing. (gostork.com)
  • Vitrification stops this from occurring, which not only protects the embryo as it freezes, but as it is "defrosted" to be transferred. (gostork.com)
OBJECTIVE1
  • Objective: To investigate whether the duration of estrogen administration before euploid embryo transfer affects clinical outcome. (mssm.edu)
Endometrium2
  • Fibroids, polyps and adhesions that develop after a surgical procedure or infection can hamper the embryo - endometrium attachment process. (intechopen.com)
  • Endometrium is a biosensor of embryo quality - it has both the capability to accept the embryo (receptivity) and select it (selectivity). (myivfanswers.com)
Fewer1
  • The need to transfer fewer embryos while maintaining or increasing PRs prompted research of various embryo evaluation methods. (medscape.com)
Results3
  • In the meantime, evidence-based results can guide you and your fertility care team in choosing the best embryos for transfer. (txfertility.com)
  • To achieve the best results, every couple needs an experienced doctor, an advanced lab for producing embryos, and an embryologist. (angelsfertility.com)
  • When results became available, frozen embryo transfer (FET) was subsequently arranged so that only euploid embryo(s) were transferred. (biomedcentral.com)
Differences1
  • A data analysist then investigated this huge amount of data and found that there were differences between these sets of embryo images, and that's how we developed CareMaps-AI: our unique embryo selection model powered by AI. (carefertility.com)
