How To Transfer One Or More Embryos Using IVF

How To Transfer One Or More Embryos Using IVF.
Women who stand in-vitro fertilization (IVF) are almost five times more liable to to give birth to a one healthy baby following the implantation of a single embryo than are women who choose to have two embryos implanted at the same time, an supranational 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 online. Approximately half of the women underwent procedures involving the singular transfer of an embryo, while the other half underwent a stand-in embryo procedure.

Overall, the study authors noted that, relative to a double embryo transfer, a only embryo transfer appears to significantly increase the chances of carrying a baby to a ample term of more than 37 weeks problem solutions. In addition to lowering the risk for premature birth, a unmarried embryo transfer also appeared to lower the risk for delivering a low birth weight baby, DJ McLernon, a on fellow with the medical statistics team in the section of population healthfulness 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 transmit in IVF," the authors wrote in their report. They added that their observations could offer everyday guidance to would-be mothers and doctors who are eager to foster optimal conditions for a successful pregnancy, while at the same convenience hoping to avoid the increased health risks associated with IVF procedures that give ascension to multiple-birth pregnancies.

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

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

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

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

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

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

"There is a consensus that there is a elated number of multiple births from IVF, and we're all doing everything we can to reduce that rate of origin 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 attain a much better outcome with two separate single embryo transfers compared with one spitting image embryo transfer - which would mean a much lower chance of a multiple pregnancy and all the coordinate complications," Stadtmauer continued.

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

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