EtiologyEtiology

• Abnormal zygotic development

– Early spontaneous abortion commonly display a developmental abnormality of the zygote, embryo, early fetus, or placenta

– 1000 spontaneous abortions analyzed by Hertig and Sheldon

•Half demonstrated degenerated or absent embryos, that is, blighted ova

The exact mechanism responsible for abortion are not apparent

In the first 3 months of pregnancy

* Death of the embryo or fetus nearly always precedes spontaneous expulsion of the ovum

* Finding of the cause of early abortion involves ascertaining the cause of fetal death

In subsequent months * The fetus frequently

does not die before expulsion

Other explanations for its expulsion should be sought

• Aneuploid abortion

Approximately 50 to 60 percent of embryos and early fetuses that are spontaneously aborted contain chromosomal abnormalities accounting for most of early pregnancy wastage

Jacobs and Hassold (1980)

95 percent of chromosomal abnormalities d/t maternal gametogenesis error, 5 percent → d/t paternal error

Monosomy XThe second frequent chromosomal abnormalityUsually results in abortionMuch less frequently in liveborn female infant (Turner syndrome)

TriploidyAssociated with hydropic placental (molar) degenerationIncomplete (partial) hydatidiform moles may contain triploidy or

trisomy for only chromosome 16Tetraploid abortuses

Rarely are liveborn and most often are aborted early in gestation

Chromosomal structural abnormalitiesIdentified only since the development of banding techniques, infrequently cause abortion

Euploid abortion

Abort later in gestational than aneuploid Three fourths of aneuploid abortions occurred before8 weeksEuploid abortions peak at about 13 weeksThe incidence of euploid abortions increased dramatically after maternal age exceeded 35 years
