Fetal death in utero

Fetal death in utero (FDIU), also known as intrauterine death (IUD), is the term used when the death of a fetus occurs after the 20th week of pregnancy. Prior to this, it is considered a miscarriage.

1% of normal, uncomplicated pregnancies end in fetal death. In ~15% of FDIU, no cause is identified.
