In 1963, Yanagimachi and Chang first succeeded in fertilizing golden hamster eggs in vitro without any contributions from the female genital tract [1]. This is the first success of 'In Vitro Fertilization (IVF)' in mammals. After this success, the protocol of IVF has been established in most of mammalian species studied up to date. At last, the Nobel Prize in Physiology or Medicine 2010 was awarded to Dr. Robert G. Edwards who reported the first success of IVF in human with Dr. Patrick C. Steptoe [2]. Also in experimental animals, IVF is a powerful tool for production of offspring. Alternatively, intracytoplasmic sperm injection (ICSI) is now available for the purpose; however, ICSI requires a great deal of skill and cannot be used for many oocytes at the same time. Thus, especially in the production of rodent offspring at the facility, IVF is a more simple and general-purpose.. View More»
