Abstract: The subject of the present invention is in vitro fertilisation (IVF) and intracytoplasmic sperm injection (ICSI), and relates to an apparatus with which embryo transfer can be standardised and which, in comparison with the currently used technique, may possibly result in higher pregnancy rates. This is realised by using an apparatus with which it is possible to precisely and reproducibly aspirate one or two embryos from a Petri dish and to transfer them to the uterus, to a particular distance from the fundus. It has been shown that the chance of pregnancy is best if the distance between the embryo and the fundus is 1-2 cm.
