[1] Symptoms can start within an hour of exposure, and can last for several months.
Fetal abnormalities are conditions that affect a fetus or embryo, are able to be diagnosed prenatally, and may be fatal or cause disease after birth. They may include aneuploidies, structural abnormalities, or neoplasms. Acardiac twin; Achondrogenesis; Achondroplasia
The term fetal alcohol effects (FAE) was used for alcohol-related neurodevelopmental disorder and alcohol-related birth defects. [1] It was initially used in research studies to describe humans and animals in whom teratogenic effects were seen after confirmed prenatal alcohol exposure (or unknown exposure for humans), but without obvious ...
It is distinct from acute radiation syndrome, in that it occurs at dose rates low enough to permit natural repair mechanisms to compete with the radiation damage during the exposure period. Dose rates high enough to cause the acute form (> ~0.1 Gy/h) are fatal long before onset of the chronic form.

The compromised stress management skills of animals whose male parent was exposed to alcohol are similar to the exaggerated responses to stress that children with fetal alcohol syndrome display because of maternal alcohol use. These birth defects and behavioral disorders were found in cases of both long- and short-term paternal alcohol ingestion.
