Assisted Reproductive Technology and Congenital Malformations
نویسندگان
چکیده
Assisted reproductive technology (ART) encompasses all medical intervention used to assist people becoming parents, mainly but not solely as a result of infertility. In vitro fertilisation (IVF) is the cornerstone of ART. It involves stimulating the ovaries, retrieving and culturing oocytes which are then inseminated with capacitated spermatozoa. The embryo is cultured and transferred into the uterus. The first successful IVF pregnancy came to term in 1978. Since then numbers have rapidly increased and it now accounts for nearly 2% of births in the UK and more than 4 million worldwide (Human Fertilisation and Embryology Authority, 2011; ICMART, 2008).
