How To Transfer One Or More Embryos Using IVF

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

Overall, the study authors noted that, relative to a double embryo transfer, a one embryo transfer appears to significantly increase the chances of carrying a baby to a shining term of more than 37 weeks enlast.drug-purchase.info. In addition to lowering the risk for premature birth, a celibate 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 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 carry in IVF," the authors wrote in their report. They added that their observations could offer useful guidance to would-be mothers and doctors who are eager to foster optimal conditions for a successful pregnancy, while at the same ease hoping to avoid the increased health risks associated with IVF procedures that give get to one's feet 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 details seemed to suggest that the double embryo transfer option does, in fact, offer the jocular mater much better odds for giving birth to a single healthy baby. While among study participants just 27 percent of isolated embryo transfer procedures resulted in the birth of a healthy baby, that participate rose to 42 percent of double embryo transfer births, the investigators found.

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

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

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

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

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

"And this certainly shows that cumulatively you can often bring off 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 allied complications," Stadtmauer continued.

"However, while a single embryo transfer is appropriate for a company of women it's not appropriate in all women. Because while in young women or women with good prognostic factors a unmarried embryo transfer can be very successful, in women over the age of 38 or women with despondent chances of pregnancy and poor 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 imperil for failure. So not all women are easily convinced to choose the single transfer option," Stadtmauer added. "So while it's patently the future, it's not for everybody yourvito. But the better we get at selecting which embryos have the highest chances of implanting, the better we can get at directing patients for elective single embryo transfers".
