The state of HCV infection and vertical transmission during assisted reproductive technology

Vertical transmission is the major route of HCV infection in children and draws much attention recently. With the development of assisted reproductive technology (ART), more and more HCV-serodiscordant infertile couples seek assisted reproduction treatment. Vertical transmission of HCV in ART cannot be avoided. Understanding the state of HCV infection of oocyte and embryo is helpful to solve the fertility problem and to control mother-to-child transmission.
