Recurrent pregnancy loss is often random, but known causes include chromosomal issues, antiphospholipid syndrome, and advanced maternal age. Unexplained cases often resolve without invasive treatments.

Area of Science:

  • Reproductive Medicine
  • Genetics
  • Obstetrics

Background:

  • Recurrent spontaneous abortion (RSA) is a complex reproductive health issue.
  • While often random, specific factors can contribute to recurrent pregnancy loss.
  • Identifying these factors is crucial for effective management.

Purpose of the Study:

  • To review the established and potential causes of recurrent spontaneous abortion.
  • To evaluate the efficacy of current diagnostic and therapeutic approaches.
  • To emphasize proactive evaluation and judicious use of interventions.

Main Methods:

  • Literature review of studies on recurrent spontaneous abortion.
  • Analysis of established etiological factors and emerging evidence.

  • Discussion of diagnostic criteria and treatment outcomes.

    • Main Results:

    • Established causes include parental chromosomal abnormalities, antiphospholipid syndrome, polycystic ovarian disease (PCOD), and advanced maternal age (>40).
    • Müllerian defects are a likely cause for some women; corpus luteum defects are less common than previously thought.
    • Lifestyle factors like smoking and alcohol may contribute to pregnancy wastage.

    Conclusions:

    • Most recurrent pregnancy loss cases are random events; specific treatable causes are rare.
    • Evidence supporting many therapies for RSA is limited, especially for unexplained cases.
    • Proactive environmental assessment is recommended over solely counting pregnancy losses; unproven, invasive therapies should be used cautiously.
