Embryos can be either "fresh" from fertilized egg cells of the same menstrual cycle, or "frozen", that is they have been generated in a preceding cycle and undergone embryo cryopreservation, and are thawed just prior to the transfer, which is then termed "frozen embryo transfer" (FET). (wikipedia.org)
Transferring at the blastocyst stage confers a significant increase in live birth rate per transfer, but also confers a decreased number of embryos available for transfer and embryo cryopreservation, so the cumulative clinical pregnancy rates are increased with cleavage stage transfer.

Provided the lab has experience freezing and thawing blastocyst stage embryos, they should suvive. (sharedjourney.com)
The main reason blastocyst stage embryos don't survive the freeze-thaw process is because they were of poor quality to begin with (not all blastocyst stage embryos are created equal - that's why we grade them). (sharedjourney.com)
When donated eggs are used, 50-60% of the embryos should make it to the blastocyst stage with majority be of top quality. (sharedjourney.com)
Athough a first time donor may look good on paper, E2 levels and U/S, the quality of the eggs cannot be ascertained until the eggs are fertilized and the embryos cultured to the blastocyst stage. (sharedjourney.com)
So, it is our policy to guarantee at least two good quality blastocyst stage embryos for transfer in a DE cycle. (sharedjourney.com)

After all, we know that the chances of poor quality embryos implanting are very poor, and that the reason for the failure was the poor quality of the embryos. (drmalpani.com)

Fibroids, polyps and adhesions that develop after a surgical procedure or infection can hamper the embryo - endometrium attachment process. (intechopen.com)

If euploid embryos are available, a single-blastocyst embryo transfer should be the standard practice, and is our practice at PFC. (pacificfertilitycenter.com)
IVF/ICSI patients with =1 previous failed euploid embryo transfer(s) or =2 previous failed transfers with non-tested good quality embryos. (who.int)

Quite often, more than one embryo will successfully implant, resulting in a multiple pregnancy. (scrcivf.com)

Because of that, younger women can transfer fewer embryos. (marieclaire.com)
Blastocyst embryos have a much higher chance of implanting than other embryos, therefore fewer embryos are required to achieve a pregnancy. (shadygrovefertility.com)
The advantage of a day 5 or blastocyst transfer is a higher implantation and pregnancy rate per embryo transferred since less "strong" embryos will not survive, and therefore the scientists and physicians are stressing all of the embryos to detect the best quality embryos and also decrease the chance of multiples such as twins, by transferring fewer embryos. (sbivf.com)
Previously it was argued that using frozen embryos could result in fewer births but current research has found that using frozen embryos can lead to a lower chance of haemorrhage, premature birth and deaths in the first few weeks of life. (abdn.ac.uk)

Various techniques constitute assisted reproduction, one of which is gamete intra-fallopian transfer (GIFT). (asu.edu)
Depending on the patient's age and the maturity of the oocytes, two to five oocytes are transferred into the fallopian tubes along with the sperm. (asu.edu)

Equine follicle-stimulating hormone (eFSH) treatment increases embryo-recovery rate in donor mares. (ivis.org)
However, the high cost of equine embryo transfer dictates that only genetically superior animals should be used as donors. (ivis.org)
Currently, single-embryo recovery attempts are common in equine-embryo transfer. (ivis.org)
This book briefly reviews the history of equine embryo transfer, covering in clinically practical terms the techniques, equipment, and management protocols currently in use. (routledge.com)
Embryo transfer has become a big business, especially for breeding racing stock (horses and camels), and is therefore a very important aspect of equine practice. (routledge.com)

Its failure may be a consequence of embryo quality, anatomical or immunological factors. (intechopen.com)

The reason for this is that many embryos have chromosomal abnormalities which mean they are not actually viable. (scrcivf.com)

More efficient and economical embryo transfer relies on the ability to induce multiple ovulations or superovulation in the donor mare, and it also depends on careful and accurate reproductive management of both the donor and recipient mares. (ivis.org)

After intracytoplasmic sperm injection (ICSI), 48 embryos were evaluated on day 3 of their development, according to their cell number. (who.int)

Not all embryos can survive in a laboratory this long, although they can result in normal pregnancies if transferred on day 3 of laboratory development. (sbivf.com)
This method does not improve the chance of pregnancy from any individual embryo, it only finds the strongest that survive. (sbivf.com)

The term refers to the failure of repeated transfers of embryos of good morphological quality. (intechopen.com)
Due to its clinical applications success of IVF results is the morphological and the expansion of non-invasive treatment quality of the embryo. (who.int)
Low-quality embryos, on the other cells, thereby maintaining a relatively low basal hand, frequently display morphological level [16-18]. (who.int)

Adverse events related to the use of embryo transfer catheters (ETCs) may be underreported to the US Food and Drug Administration (FDA), according to a new study presented at the 2023 annual meeting of the American Society for Reproductive Medicine. (medscape.com)

The transfer catheter has an internal support cannula. (cookmedical.com)
With hundreds of thousands of embryo transfers being performed per year, surveillance of the safety, performance, and quality of embryo transfer catheter devices is critical and should not be taken for granted," said Anita Madison, MD, MPH, from the Division of Reproductive Endocrinology and Infertility at Johns Hopkins School of Medicine in Baltimore, who led the study. (medscape.com)

I had 2pn frozen embryos (donor egg) cultured for 5 days and transferred a grade 2 blastocyst and a 3bb blastocyst. (sharedjourney.com)

Clinical outcomes of vanishing twin syndrome and selective fetal reduction after double embryos transferred in IVF pregnancy: A propensity score matching study. (bvsalud.org)

Increased early embryonic mortality and pregnancy loss following ART is attributed to the exposure of the gametes and embryos to a suboptimal unnatural environment for a shorter or a longer time during the crucial and vulnerable period of gametogenesis and early embryonic development, which invariably imposes stresses upon them. (ugent.be)

The modern approach to IVF involves blastocyst culture and biopsy followed by PGT and a single embryo transfer. (medscape.com)
Edwards and Gardner successfully performed the first known embryo biopsy on rabbit embryos in 1968. (medscape.com)

The transfer of multiple oocyctes carries the possibility of multiple pregnancies, which occurs in an estimated thirty percent of assisted reproductive pregnancies. (asu.edu)
Here s one example: National data from 2013 showed that clinics performing more elective single-embryo transfers (eSETs) in women younger than 38 have lower rates of multiple pregnancies but without sacrificing birth rates. (pacificfertilitycenter.com)
4 And nearly half of all multiple pregnancies resulting from ART in this country occur in women under age 35 who have had 2 fresh or frozen embryos transferred. (pacificfertilitycenter.com)
Since most countries have a restriction on the number of embryos that can be transferred at a time, to avoid the risk complications during multiple pregnancies, the spare or supernumerary embryos are generally frozen for future use. (fertilityproregistry.com)

however, the 3 groups were similar with respect to the cause of infertility, total dose of follicular stimulating hormone (FSH), number of oocytes and embryos obtained, and number and quality of embryos transferred. (who.int)

Laboratories have developed grading methods to judge oocyte and embryo quality. (wikipedia.org)
GH beneficial effect on oocyte quality is shown in several studies, but GH effect on uterine receptivity is not clear. (medscape.com)
[ 14 ] In addition to its direct effect on the oocytes and/or cumulus cells, GH may also influence oocyte quality indirectly, through activation of insulin-like growth factor-I synthesis or promotion of follicle-stimulating hormone-induced ovarian steroidogenesis (reviewed in [ 15 ] ). (medscape.com)

If implantation occurs successfully, the embryo begins to produce the hCG hormone, a sign of an ongoing pregnancy. (fertilab.com)
Since implantation occurs 3 - 8 days after the embryo transfer ( depending upon whether you have had a Day 3 transfer or a blastocyst transfer), this means that the HCG produced by your embryo will be first detectable in your bloodstream only after this time. (drmalpani.com)

The number and quality of a woman's oocytes declines with age. (medscape.com)
The number of embryos transferred is determined by the woman's age and likelihood of response to IVF. (msdmanuals.com)

After all, once they've done an embryo transfer, they can tell the patient, "Look , I completed your IVF treatment, and have done everything humanly possible " , so the patient is happy that the doctor did a good job. (drmalpani.com)
They strive to produce moderately framed cattle with good fleshing ability, structural soundness, maternal value and the ability to perform well on average-quality fescue-based forage. (purinamills.com)
How do you assess what is a 'good' embryo? (carefertility.com)
Traditionally, embryologists would assess embryo quality by looking down a microscope and subjectively assessing an embryo based on their number of cells, how smooth and even those cells are, and whether or not there is any fragmentation (bits of cells that have broken off, which generally is not a good sign). (carefertility.com)
which helps us determine which embryos are actually good quality, whether they appear to be or not. (carefertility.com)
He said evaluating quality was a little difficult at the early stages but that they looked good. (sharedjourney.com)
I am trying to relax so I am not so stressed so I am hoping you could give me a clue about if these are good embryos or not. (sharedjourney.com)
The good quality embryo rate was higher in VT group (72.7% vs. 63.3%, p = 0.001) compared with the singleton group. (bvsalud.org)
To additional good-quality embryos are ET). (who.int)
In all the cen- are the most common complication etc.). tres, only good-quality embryos were associated with IVF treatment. (who.int)
Good quality ES cells of low passage are recommended. (lu.se)
Although good quality ES cells can provide chimeras, we do not guarantee germline transmission. (lu.se)

An embryo was flushed, then transferred into a recipient mare which is when the waiting began. (selectbreeders.com)
Biorepositories vary agreement between the provider of research materials considerably, ranging form formal organisations and the recipient of the materials, setting forth to informal col ections of materials in an individual conditions of transfer and use, protecting proprietary researcher's freezer. (who.int)

We have 3 frozen embryos that have been genetically tested and our plan moving forward was to do a FET (frozen embryo transfer) to expand our family. (eatsleepwear.com)

The research team thawed a small number of embryos in 2016, and transferred them to nine female bison. (sciencedaily.com)

Some patients will end up with all their embryos being of poor quality on Day 3, and then they're not certain what to do. (drmalpani.com)
Results of GIFT vary depending on the age of the patients and the quality of the sperm. (asu.edu)
Patients who have a condition that may worsen significantly with a multiple pregnancy should limit the transfer of embryos to 1. (pacificfertilitycenter.com)
Some patients are better served having a day 3 embryo transfer. (sbivf.com)
The problem is that some IVF clinics will fool their patients into believing they are pregnant by giving them a HCG injection 7 days after the embryo transfer. (drmalpani.com)
SET, FT-ET and double-embryo transfer were used in 5632 patients after legislation, while traditional IVF and FT-ET approach was used in 6029 patients before legislation. (who.int)

The way we assess embryo quality has significantly improved over the past few years, with great technological advancements allowing us to analyse embryos in our IVF laboratories in even more detail and with more certainty than ever before. (carefertility.com)
