HUMAN PHENOTYPE - ANNOTATIONS

The Human Phenotype Ontology (HPO) is downloaded weekly from http://compbio.charite.de/hudson/job/hpo/lastStableBuild/artifact/ontology/release/hp.obo. The file downloaded is considered the "last stable build" available for the ontology. For more about the HPO, view their website at http://www.human-phenotype-ontology.org/.

Definition:It is estimated that about 40-70 percent of human embryos produced in vitro fertilization (IVF) and intracytoplasmic sperm injection (ICSI) are viable embryos, whereas others arrest at different early stages of development. The phenotype of preimplantation lethality is inferred if IVF and ICSI cycles fail because all of an individual's embryos are arrested at early stages of development.
Synonyms:exact_synonym: Early embryonic arrest;   Preimplantation embryonic lethality
