Assisted reproductive technology (ART) is a general term referring to methods used to achieve pregnancy by artificial or partially artificial means. It is reproductive technology used primarily in infertility treatments. Some forms of ART are also used in fertile couples for genetic reasons. ART is also used in couples who are discordant for certain communicable diseases, i.e. Aids, to reduce the risk of infection when a pregnancy is desired. The term also includes any reproductive technique involving a third party e.g a sperm donor. There is yet no strict definition of the term.
