INTRODUCTION In vitro fertilization and embryo transfer (IVF-ET) is the most basic Assisted Reproduction Technique and is designed to enhance the likelihood of conception in couples in whom other methods of fertility have been tried and are unsuccessful. IVF-ET involves multiple steps leading to insemination and fertilization of eggs in the laboratory. The embryos thus created are placed into the uterus for implantation. Each stage of the procedure has to be carefully managed and has its own specific risks. RISKS OF THERAPY More chances of multiple pregnancy In IVF, ovaries are stimulated to produce several eggs rather than a single egg as in a natural cycle. Multiple eggs and multiple embryos, increase the number of embryos available for transfer and ultimately, the probability of multiple conception. |
