Embryonic and early fetal loss.

T H Shepard, A G Fantel

    Clinics in Perinatology
    |September 1, 1979
    PubMed
    Summary

    Approximately half of all pregnancies result in early pregnancy loss, often due to chromosomal abnormalities. Environmental factors also contribute to this reproductive wastage, necessitating further study for prevention.

    Area of Science:

    • Reproductive biology
    • Genetics
    • Teratology

    Background:

    • Early pregnancy loss, including embryonic and fetal loss, affects up to 50% of pregnancies.
    • Karyotype deviations are frequently observed in early abortuses, correlating with high rates of gross abnormalities.
    • Environmental factors such as radiation, smoking, anesthetics, and prior abortions may increase pregnancy wastage.

    Purpose of the Study:

    • To investigate the causes of high rates of embryonic and early fetal loss.
    • To identify new embryonic and fetal syndromes through the analysis of abortuses.
    • To establish the role of karyotype deviations and environmental factors in pregnancy wastage.

    Main Methods:

    • Analysis of abortus material to identify embryonic and fetal syndromes.
    • Karyotyping of early abortuses to determine the prevalence of chromosomal abnormalities.
    • Review of environmental factors potentially contributing to pregnancy loss.

    Main Results:

    • Karyotype deviation is a common finding in early abortuses.
    • Analysis of abortuses has led to the identification of novel embryonic and fetal syndromes.
    • Environmental factors are implicated as contributors to pregnancy wastage.

    Conclusions:

    • Understanding the etiology of pregnancy loss through abortus analysis is crucial.
    • Monitoring and classification of abortuses aid in reproductive counseling and defense against teratogenic exposures.
    • Further study promises to elucidate the causes and control of preventable pregnancy wastage.
