All options accurately describe the processes involved in in vitro fertilization and embryo transfer. IVF-ET does not increase the risk of birth defects, but about 25% of successfully implanted fertilized eggs can end in spontaneous abortion. Multiple pregnancies are not uncommon. The gestational sacs chosen for termination are administered with potassium chloride, and for this reason, IVF-ET deals with many ethical issues.
