Multiple gestations in 
assisted reproductive technology: can they be avoided with blastocyst transfers?
However, because singletons conceived by this technology--even if they were born at term and the pregnancy had involved a single fetus-have an increased risk of low birth weight, the investigators conclude that "infants from both singleton and multiple births must be considered in assessing the effect of 
assisted reproductive technology on the rate of low birth weight in the United States."
Participation in this program is a requirement for membership in ASRM affiliate organizations, such as the Society for 
Assisted Reproductive Technology. In the near future, it is expected that it will be difficult for embryology labs to receive insurance reimbursement without SART membership.
While it is commendable that the courts and the Task Force have delegated the ultimate decision-making authority over cryopreserved pre-zygotes to the gamete providers themselves,(103) this does little, if anything, to elucidate and resolve the complex legal questions inherent in 
assisted reproductive technology, both for the parties in dispute and for society at large.
Advocates of 
assisted reproductive technology concede these points.
SAN FRANCISCO -- The higher the dose of gonadotropin for ovarian stimulation, the lower the five birth rate, a retrospective study of 541,967 cycles of 
assisted reproductive technology showed.
The reports said that, of the women who took part in the study, 45 (0.5 per cent) reported at least one virgin pregnancy, that was unrelated to the use of 
assisted reproductive technology, the Independent reported.
All 
assisted reproductive technology (ART) cycles entered into the US national 
Assisted Reproductive Technology database from 2004 through 2009 were linked to individual women in order to estimate cumulative live-birth rates which, for 246,740 women with 471,208 ART cycles were 140,859 live births.
