Time-Lapse Imaging: Why Are There So Few Randomized Controlled Trials?

Volume 4 • Issue 2 • 1000e123 JFIV Reprod Med Genet ISSN: 2375-4508 JFIV, an open access journal As researchers in human clinical embryology, we all know about the fascination what new ideas in the field of assisted reproduction impose on us. Usually it is a short step from learning about something new starting our own research activities in order to elaborate on how to try and implement them into routine. This has happened with microinjection, which after being developed for DNA transfer into pronuclei for animal research attracted attention in the human IVF field and resulted in techniques like SUZI (subzonal insemination) [1] and finally ICSI (intracytoplasmic sperm injection) [2]. Another technology that challenged our field was vitrification and although the principle was known for decades [3], the implementation process of vitrification for freezing of oocytes and embryos was a very fast one [4].
