Endometrial receptivity investigating (ERT) did not summation the chances of achieving unrecorded commencement successful patients undergoing in vitro fertilization.
The survey was promoted by wide usage of the tests successful reproductive medicine and earlier conflicting studies regarding its effectiveness. The procedure, successful which doctors extract cells from a woman's endometrial lining successful an effort to find the champion time to execute successful vitro fertilization, requires a biopsy, tin instrumentality a period to make results, and costs up to $1000.
But the caller study, published online December 6 successful the Journal of the American Medical Association, recovered that embryo transportation based connected the timing of ERT was nary amended than that based connected the modular protocol.
"Endometrial receptivity investigating ended up not being beneficial successful the colonisation of interest, a bully prognosis IVF diligent population," said Nicole Doyle, MD, PhD, of Shady Grove Fertility, successful Arlington, Virginia, who led the study. "For this peculiar diligent colonisation I would not urge ERT based connected the results of the trial."
"Unfortunately, arsenic is our past successful reproductive medicine, we whitethorn embrace technology prematurely fixed diligent desperation and doc eagerness to amended gestation outcomes," said Mark P. Trolice, MD, manager of The IVF Center successful Orlando, Florida, who was not progressive successful the caller research.
The double-blind, randomized objective proceedings enrolled 726 women treated astatine Doyle's session betwixt May 2018 and September 2020.
All the women underwent ERT. Of those who received adjusted progesterone vulnerability aft the test, unrecorded commencement occurred successful 58.5% of transfers (223 of 381). Among those successful a power radical who did not person their progesterone adjusted aft ERT and underwent IVF connected a standardized schedule, 61.9% of transfers (239 of 386) resulted successful unrecorded birth, according to the researchers.
The differences successful rates of objective (77.2% vs. 79.5% [95% CI, −10.4% to 2.4%]) and biochemical gestation (68.8% vs. 72.8% [95% CI, −8.2% to 3.5%]) were not statistically important betwixt the 2 groups, Doyle and her colleagues reported.
Women who experienced recurrent implantation nonaccomplishment (RIF), defined arsenic much than 2 failed embryo transfers, were excluded from the study. "We can't measure the payment of an endometrial receptivity investigating successful this peculiar diligent population," Doyle said.
However, she noted that the fig of women who acquisition RIF is "a precise tiny fraction of each IVF patients, little than 5%." Of those, fractional are expected to person embryos that are not suitable for implantation, Doyle said.
As a result, she said, "it's truly lone astir 2.5% of IVF patients for which we don't yet person an reply regarding the inferior of ERT"
Trolice, besides a prof astatine UCF College of Medicine, expressed certainty that the "one-size-fits-all approach" for ERT has been disproven by the study's nonaccomplishment to find a payment from the process successful women with a "good prognosis." But, helium added, whether ERT is of worth successful a subset of patients, specified arsenic those with recurrent implantation failure, remains "a question of captious importance."
Doyle and Trolice reported nary applicable fiscal relationships.
