technology

 [tek-nol´ah-je]
scientific knowledge; the sum of the study of a technique.
assisted reproductive technology (ART) any procedure that involves manipulation of eggs or sperm to establish pregnancy in treatment of infertility, such as in vitro fertilization, gamete intrafallopian transfer, tubal embryo transfer, and zygote intrafallopian transfer.

as·sist·ed re·pro·duc·tive tech·nol·o·gy

originally, a range of techniques for manipulating oocytes and sperm to overcome infertility; encompasses drug treatments to stimulate ovulation, surgical methods for removing oocytes (for example, laparoscopy and ultrasound-guided transvaginal aspiration) and for implanting embryos (for example, zygote intrafallopian transfer or ZIFT), in vitro and in vivo fertilization (for example, artificial insemination and gamete intrafallopian transfer or GIFT), ex utero and in utero fetal surgery, and laboratory regimes for freezing and screening sperm and embryos as well as micromanipulating and cloning embryos as well as See: eugenics.

assisted reproductive technology

n.
Any of various techniques for enhancing fertility, such as in vitro fertilization, in which both the egg and the sperm are manipulated.

assisted reproductive technology

The range of technologies used in the treatment of infertility. These include in vitro fertilization, the use of frozen embryos, embryo screening, testicular sperm retrieval, sperm microinjection, chromosome screening, frozen ova and long-frozen sperms from dead donors.

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.

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.
