Role of the private sector

摘要

Hurley's article on new technologies in infertility treatment requires a response. In more than 30 years of in vitro fertilisation, assessment of embryo quality has changed little. It is based on subjective assessment consisting of two or three examinations over 2-5 days, during which embryos are removed from their controlled environment. The "best" embryo is not always selected, and adverse epigenetic phenomena may be associated with prolonged culture. Several time lapse systems allow assessment of embryo development without disturbance and provide additional information on development. We have introduced the Eeva system, which is superiorto human assessment in predicting developmental potential and increases the probability of selecting euploid embryos.
