What is Selective Reduction?
by Pattie Hughes
Selective reduction is a procedure used to reduce the number of embryos in a multifetal pregnancy. This procedure is sometimes used when too many embryos implant in a pregnancy that is achieved with assisted reproductive technology. When too many embryos implant successfully the chance of carrying the pregnancy to term drops significantly. [I agree. Which is why I am against assisted reproductive technology in the first place. It creates pregnancies with an unnaturally high number of babies, which leads to a number of related problems both physical and ethical. However, if someone still goes ahead and goes through with the procedure, I am certainly in favor of keeping all babies. The same technology that got "parents" in this predicament in the first place has become very sophisticated at ensuring relatively safe outcomes even for those pregnancies. There were two sets of sextuplets born at a hospital in our city in the last year. The babies in both cases were well and healthy. I think parents who chose S/R are not so much concerned about the wellbeing of the children as simply not being willing to take home 3, 4, or more babies at the same time. Also, having a baby that needs to be cared for in the NICU is not the glamorous picture of a bouncing pink baby that selfish IVF parents were hoping to show around.]
Selective reduction is generally used for pregnancies with more than two fetuses. [I hope that doesn't mean some people actually choose to kill one of two twins. But nothing surprises me any more.] Preventing medical problems in the pregnancy or the loss of all the fetuses is the reason for the procedure. In some cases, fetuses that are considered to be at greater risk for defects are selected for reduction. [Yeah, because who would willingly pick a lesser, i.e. potentially disabled child? Why take the "greater risk for defects" when you can get a perfect specimen? Are these parents being judgmental of their offspring???]
The procedure is done during the first trimester, prior to the twelfth week of pregnancy. If no abnormalities are present in any of the fetuses, the ones that are easiest to reach are selected for reduction. [Does reading this make you sick?] A chemical, usually potassium chloride, is injected into the selected fetuses.
Following the procedure, the fetuses are usually absorbed by the mother's body. [How can you go to sleep knowing that your body is absorbing the children you killed?] The procedure is not without risk. In some cases, one or all of the remaining fetuses will die as well. This happens in about five percent of cases. Preterm labor is another possible side effect of this procedure. [Wow, that kind of sounds exactly like what happened to Tortua. What a shock! So we aren't allowed to feel bad that she killed 2 babies, but we do have to pity her for the other 2 dying as well or we will be called heartless, cruel, and judgemental. I feel bad for mothers who legitimately lose a baby through miscarriage, stillbirth, preterm labor, or other complications, but not for women whose babies died as a result of their siblings being poisoned in utero.]
Some patients have issues with this procedure, usually for ethical or religious reasons. [That's me!] Selective reduction is a form of abortion. Pro life patients may object to this procedure for this reason. Even pro choice patients may have problems with selective reduction. A couple who has gone down the long, painful road of infertility may not be able to bear the thought of aborting some of their babies. [Well, apparently, some can.]
