Scientists Discover Test Boosting IVF Success Rates By 50%


According to released figures, the average IVF clinic has a typical IVF success rate of just 20-30 per cent, but after recent fertility research, scientists  have found a brand-new means of recognizing embryos that can be effectively implanted into the womb, increasing IVF success rates to around 50 %.

Researchers from the University of Oxford say that it is the presence of high levels of DNA from energy-producing cells in the embryo that will make an embryo fail to implant. The IVF group of scientists have actually discovered a limit, or cut-off point, below which embryos would be guaranteed for a successful implant, and above which many would fail to do so, having actually examined whether the amount of mitochondrial DNA found to be present in early-stage embryos would affect the chances of implantation after being moved into the womb.

IVF study researcher Dr Elpida Fragouli, stated that this newly found test was in effect a "new independent bio-marker of embryo practicality", which would help doctors to pick the embryos which were most likely to lead to a successful pregnancy.

She stated that the majority of IVF centers had a typical success rate of in between 20 & 30% of women having a baby after being treated with IVF, but that this figure could be enhanced to about 40 % after pre-implantation genetic screening of the egg or embryo for chromosome irregularities which are one of the major causes for miscarriages.

She went on to state that her belief was that by including this discovery to the evaluating procedure, success rates could increase approximately anything in between 50 and 60 %, and that currently 4 or 5 IVF centers in the UK and Spain were already carrying out the brand-new test as part of their evaluating treatment, which their feedback would permit them to officially release their findings to the international IVF community.

The group of IVF professionals led by Dr Fragouli took biopsies from 392 various embryos at the five day stage of development produced by couples at 8 UK centers. The team also performed study on 87 ladies aged around 38 by transferring the embryo into the womb, and leading to 44 effective pregnancies and 48 implantation failures.

Dr Fragouli said… "The findings revealed high levels of mtDNA in embryos lugging genetic defects and those from older ladies, particularly those over 40. The team found healthy embryos efficient in being implanted into the womb had the tendency to have lower levels of mtDNA than those failing to implant." She went on to discuss that it was still unclear why high levels of mtDNA must affect implantation, though it was an indication that the embryo could be under stress.

High IVF expenses are quite often the main obstacle for a successful fertility treatment, and lots of UK couples are beginning to look abroad for their IVF treatment, with Spain being the most popular destination in Europe.
