  Fertility & IVF Center of Miami Florida - Selective Reduction
Selective reduction is a technique that is used when multiple embryos have implanted as the result of assisted reproductive technologies.
Selective reduction is performed by a perinatologist on an outpatient basis by inserting a needle guided by ultrasound either through the abdomen or vagina to inject potassium chloride into the fetus.
The decision of whether or not to undergo selective reduction can be a traumatic one, and couples who have invested time and effort to achieve pregnancy may often be unprepared to make this choice.

Selective reduction (or fetal reduction) is the practice of reducing the number of fetuses in a multifetal pregnancy (i.e.
Selective reduction is most often used to reduce a higher-order multiple pregnancy (one with three or more fetuses) to a twin or singleton pregnancy.
Selective reduction can be a very difficult decision for those who choose to make it; in many cases it is a decision faced by couples who used fertility treatments that resulted in a multifetal pregnancy.

 Abortion, selective
Selective abortion, also known as selective reduction, refers to choosing to abort a fetus, typically in a multi-fetal pregnancy, to decrease the health risks to the mother in carrying and giving birth to more than one or two babies, and also to decrease the risk of complications to the remaining fetus(es).
The term selective abortion also refers to choosing to abort a fetus for reasons such as the woman is carrying a fetus which likely will be born with some birth defect or impairment, or because the sex of the fetus is not preferred by the individual.
Selective reduction is usually performed between nine and 12 weeks of pregnancy and is most successful when performed in early pregnancy.

 Multifetal Pregnancy Reduction
The reduction procedure is usually performed between the 10th and 12th weeks of pregnancy by injecting one or more of the fetuses.
Fetal reduction increases the chance of a mother having one or two healthy babies instead of a miscarriage or very premature delivery of three or more babies who are much more likely to die or to suffer from long-term disability.
To now have to consider reduction (killing?) of some (or even one) of the babies that they have strived so hard to conceive, goes against all of the time, energy, disappointment, heartbreak and money that was invested in getting pregnant in the first place.

Selective Reduction of Multiple Pregnancy Selective reduction of multiple pregnancy [FN5] is a procedure now available to many women who find themselves encountering a multiple pregnancy [FN6] as a result of infertility treatment.
Although the medical literature's discussions of selective reduction do at times note the need to provide infertility patients with this information, anecdotal accounts from infertility patients indicate that the first time some couples learn about selective reduction is when a high order multiple pregnancy has already been diagnosed.
I use the term 'couple' deliberately, particularly with respect to selective reduction, for the vast majority of high order multiple pregnancies are the result of infertility treatment and the vast majority of recipients of infertility treatment are married couples.

 Selective reduction of edible fats and oils - Patent 4424163
Selective reductions of fatty materials occur using a catalyst consisting of essentially of zerovalent nickel dispersed on a support which shows strong metal, support interaction.
It must be clearly recognized and understood that although this definition of selective hydrogenation utilizes a specific decrease in iodine value of a particular edible oil, a selective hydrogenation may cause a greater decrease in iodine value and/or be effected with a different edible oil.
Because the selectivity of hydrogenation seems to increase with increasing temperature and decreasing pressure, there is some advantage to operating at the highest possible temperature and lowest possible pressure consistent with an acceptable reaction rate.

 Winpar Holdings Ltd v Goldfields Kalgoorlie Ltd [2001] NSWCA 427
7 A selective reduction of capital, relevantly a capital reduction which did not apply to each shareholder in proportion to the number of shares held with the terms of the reduction the same for each shareholder, could be made pursuant to ss 256B and 256C of the Law in its Part 2J.1.
His Honour erred in finding that the proposed reduction of capital was fair and reasonable to the company’s shareholders as a whole, notwithstanding that the terms of the reduction involved an appropriation of value from the minority shareholders to the majority shareholder.
Where such a selective reduction is effected by giving those whose shares are to be cancelled, not cash emanating from the reducing company but shares in another company (typically the new holding company), it is well accepted that such a process requires a scheme of arrangement.

 PHI305: Fertility Presentation
Selective reduction is a process used to reduce the number of developing fetuses in the case of a multiple pregnancy.
Selective reduction is usually performed as soon as possible because the longer the mother carries the multiple fetuses the greater the negative consequences on the remaining fetuses.
These risks of selective reduction, termed by some of its opponents as selective feticide, include: the accidental loss of pregnancy, the performance of the procedure on the wrong 'healthy' fetuses, chorioamnionitis (inflammation of the tissues surrounding the fetus), premature dilivery, and permanent damage of the surviving fetuses.

 BBC - Health - Ask the doctor - Pregnancy - selective reduction
The issue of aborting one or more of the unborn babies (or foetuses) in a multiple pregnancy (often called selective reduction) has been the centre of huge debates, partly because the increased use of infertility treatments has lead to an epidemic of multiple births in recent years.
Unless a particular foetus is being aborted because of medical problems, which one is selected is simply a practical matter of which is easiest to see and reach.
Without selective reduction 13 per cent of multiple pregnancies end with no live babies, and more than 15 per cent end with premature babies.

 Jahrbuch-CD der MPG 2003 - Selective reduction by dopamine
Selective reduction by dopamine of excitatory synaptic inputs to pyramidal neurons in primate prefrontal cortex
Using paired recordings from synaptically connected pyramidal neurons we have determined the basic properties of unitary synaptic connections between layer 3 pyramids in the primate PFC and, interestingly, we found that dopamine does not reduce synaptic transmission between nearby pairs of synaptically coupled PFC pyramidal neurons.
This input specificity may be a critical aspect of the dopaminergic regulation of recurrent excitatory circuits in the PFC.

 Selective Reduction with Multifetal Pregnancy
I have been trying to find information on selective reduction.
Fetal reduction is the termination of one or more of these fetuses, leaving the rest to continue to term.
With success rates of 80 percent or more, this procedure appears both relatively safe (for the mother and the remaining fetuses) and an effective alternative to avoiding the many complications associated with pregnancies greater than twins or triplets.

 Political Animal: Comment on "Selective Reduction"   (Site not responding. Last check: 2007-10-06)
Most women who have selective reduction--which is not unusual as part of infertility treatment--are doing it to increase their chances of having one or two healthy babies instead of miscarrying three or four at 22 weeks.
So....while this woman selectively aborting two fetuses sounds a little callous at first read, until she is aborting two conscious human beings, she is doing little more than removing two growths that she no longer wants, something dermatologists do every day of the week.
I know a woman who had a selective reduction (one of three fetuses) because it dramatically increased the chance that at least one would be born alive and that she'd carry past week 32.

 Selective Catalytic Reduction
It is important to note that the term "natural selection" is often used in the inaccurate yet fairly harmlessmetaphorical sense as having causal status.
The basic concept of natural selection is that conditions (or "nature") determine (or "select") how well particular traits oforganisms can serve the survival and reproduction of the organism; organisms lacking these traits might die before reproducing,or be less prolific.
In chemistry, reduction is the reverse of oxidation, i.e.

described a selective reduction process using cyanuric acid, reported to be effective over a broad temperature range.
Here we report new data that indicate that the same reductions can be achieved without stainless steel to activate the reaction mechanism, if the process is combined with reburning or staged combustion (or slightly fuel-rich operation in internal combustion) to produce carefully controlled stoichiometry.
reductions that can be achieved with cyanuric acid and other −NH- and −CN-containing compounds at relatively low temperatures exceed those possible with either combustion modifications or selective reduction techniques alone or in normal combination.

 The Revenge of Conscience   (Site not responding. Last check: 2007-10-06)
First, The Los Angeles Times ran a story that, in all its horrible brutality, attempted to defend a couple's decision to kill selected fetuses in the woman's womb by means of what is euphemistically called "selective reduction." The article was chilling in its cold honesty and grotesque morality.
Selective reduction is one of the most unpleasant facts of fertility medicine, which has helped hundreds of thousands of couples have children but has also produced a sharp rise in high-risk multiple pregnancies.
In 20-odd years, he estimates, a "handful" of pregnancies have miscarried shortly after his performing the reduction, and with a less experienced practitioner, the risk of procedure-caused miscarriage is higher, probably just under 1 percent.

 Winpar Holdings Limited v Goldfields Kalgoorli Limited [2000] NSWSC 728 revised 26/07/2000
7 The present challenge to the selective reduction of capital not only contends that its terms are not fair and reasonable but also that there has been a failure to provide “all information known to the company that is material to the decision on how to vote on the resolution” pursuant to s256C(4).
In particular, the absence of GKL or its parent was a necessary protection to ensure that an entity with a materially different interest in the transaction should not be in a position to influence the outcome of the vote.
45 Where such a selective reduction is effected by giving those whose shares are to be cancelled, not cash emanating from the reducing company but shares in another company (typically the new holding company), it is well accepted that such a process requires a scheme of arrangement.

 We call it ‘selective reduction’ » GetReligion
It would be just as easy to praise her for shedding light on the monstrosity of “selective reduction.” I thought it was, like many of Stephanie Simon’s stories, rather balanced — which is interesting because Simon had an abortion story that wasn’t terribly balanced.
Also, it is worth noting that the medical staff who kill the fetuses use the euphemism “selective reduction” to explain the process to their patients.
As we discussed all our options, the term selective reduction came up—our doctor was never a proponent of it, but he did say, “This is a possibility.” We did not do IVF, in part because of the ethical implications.
