How To Transfer One Or More Embryos Using IVF

How To Transfer One Or More Embryos Using IVF.
Women who be subjected to in-vitro fertilization (IVF) are almost five times more tenable to give birth to a separate healthy baby following the implantation of a single embryo than are women who choose to have two embryos implanted at the same time, an ecumenic team of experts has found. The finding comes from an analysis of details involving nearly 1400 women who participated in one of eight different embryo transfer studies more. Approximately half of the women underwent procedures involving the unmarried transfer of an embryo, while the other half underwent a hypocritical embryo procedure.

Overall, the study authors noted that, relative to a double embryo transfer, a sole embryo transfer appears to significantly increase the chances of carrying a baby to a unqualified term of more than 37 weeks view. In addition to lowering the risk for premature birth, a unattached embryo transfer also appeared to lower the risk for delivering a low birth weight baby, DJ McLernon, a study fellow with the medical statistics team in the section of population haleness at the University of Aberdeen in the United Kingdom, and colleagues reported in the Dec 22 2010 online copy of BMJ.

"Our review should be useful in informing decision making regarding the number of embryos to transmittal in IVF," the authors wrote in their report. They added that their observations could offer hands-on guidance to would-be mothers and doctors who are eager to foster optimal conditions for a successful pregnancy, while at the same span hoping to avoid the increased health risks associated with IVF procedures that give arise to multiple-birth pregnancies.

The authors concluded that doctors should advise patients to choose the single embryo change option over what appears to be the less optimal double embryo transfer option.

At face value, the matter seemed to suggest that the double embryo transfer option does, in fact, offer the or formal much better odds for giving birth to a single healthy baby. While among study participants just 27 percent of unwed embryo transfer procedures resulted in the birth of a healthy baby, that pattern rose to 42 percent of double embryo transfer births, the investigators found.

However, that proliferating was narrowed considerably when the authors focused on those women undergoing an initial single embryo take procedure who then underwent a second single implant (of a frozen embryo). That framework (in which, in essence, two single embryo transfers are conducted in sequence) prompted a 38 percent ascendancy rate - a figure just 4 percent shy of the 42 percent good rate attributed to two embryos being implanted simultaneously.

What's more, the researchers further found that a isolated embryo transfer offered women an 87 percent better chance of carrying a infant to full-term than a double embryo transfer.

In addition, the single embryo transfer entailed just one-third of the imperil (compared with the double embryo transfer procedure) that the mother would ultimately deliver a plebeian birth weight baby.

Commenting on the study, Dr Laurel Stadtmauer, an associate professor of obstetrics and gynecology and IVF affiliate director of the Eastern Virginia Medical School Jones Institute for Reproductive Medicine in Norfolk, Va., described the trend effort as "very convincing".

"There is a consensus that there is a momentous number of multiple births from IVF, and we're all doing everything we can to reduce that rate of beginning because we know that premature birth and multiple births do lead to a higher risk for the babies and for the mother".

"And this certainly shows that cumulatively you can often get a much better outcome with two separate single embryo transfers compared with one treacherous embryo transfer - which would mean a much lower chance of a multiple pregnancy and all the akin complications," Stadtmauer continued.

"However, while a single embryo transfer is appropriate for a number of women it's not felicitous in all women. Because while in young women or women with good prognostic factors a distinct embryo transfer can be very successful, in women over the age of 38 or women with low chances of pregnancy and substandard prognostic factors, there would be a significant reduction in success compared to a double pregnancy transfer," she cautioned.

"There are also economic and emotional costs to undergoing a procedure twice, particularly as there is always a risk for failure. So not all women are certainly convinced to choose the single transfer option. So while it's decidedly the future, it's not for everybody visit this link. But the better we get at selecting which embryos have the highest chances of implanting, the better we can get at directing patients shortly before elective single embryo transfers".
