That way, the risks for the mother and fetuses are decreased. The appropriate number of embryos to be transferred depends on the age of the woman, whether it is the first, second or third full IVF cycle attempt and whether there are top-quality embryos available. According to a guideline from The National Institute for Health and Care Excellence (NICE) in 2013, the number of embryos transferred in a cycle should be chosen as in following table:
Also, it is recommended to use single embryo transfer in all situations if a top-quality blastocyst is available. Management
Bed rest has not been found to change outcomes and therefore is not generally recommended outside of a research study. Selective reduction (procedure)
Selective reduction is the practice of reducing the number of fetuses in a multiple pregnancy; it is also called "multifetal reduction".The procedure generally takes two days; the first day for testing in order to select which fetuses to remove, and the second day for the procedure itself, in which potassium chloride is injected into the heart of each selected fetus under the guidance of ultrasound imaging. Risks of the procedure include bleeding requiring transfusion, rupture of the uterus, retained placenta, infection, a miscarriage, and prelabor rupture of membranes. Each of these appears to be rare.
In these cases, the recommendation is cryotherapy in combination with topical mitomycin C, which is a chemotherapeutic agent. == References ==
