New Research Suggests Increased Number of IVF Cycles Can Be Beneficial
Researchers from the University of Bristol, in England reviewed the medical records of almost 160,000 women in the United Kingdom who underwent nearly 260,000 full IVF cycles between 2003 and 2010. They examined live birth rates among these women thru 2012.
They found that women under the age of forty who used their own eggs had a 33 percent success rate within the first cycle. This rate remained at above 20 percent up to and including the fourth cycle. By the sixth cycle, women had a cumulative live birth rate of 68 percent. Women between ages forty and forty-two, also saw an increased success rate up until the ninth cycle.
Overall, researchers reported that patients had an increased chance of success up to the ninth cycle of IVF. These findings support extending the number of IVF cycles.
