Summary

Embryoscopy offers early first-trimester visualization of embryos and fetuses. This technique enables developmental milestone identification, anomaly diagnosis, and embryonic circulation access for potential future therapies.

Area of Science:

  • Reproductive Medicine
  • Fetal Medicine
  • Medical Technology

Background:

  • Early pregnancy assessment is crucial for monitoring fetal development.
  • Minimally invasive techniques are needed for first-trimester diagnostics.
  • Existing methods have limitations in direct embryonic visualization.

Purpose of the Study:

  • To introduce embryoscopy as a novel technique for direct embryo/fetus visualization.
  • To assess the feasibility of embryoscopy for diagnosing early developmental anomalies.
  • To explore the potential of embryoscopy for fetal interventions.

Main Methods:

  • A rigid fiberoptic endoscope is utilized for transcervical insertion.
  • The endoscope is advanced into the extracoelomic cavity for visualization.
  • Embryonic/fetal blood sampling was performed to assess circulatory access.

Main Results:

  • Embryoscopy allows direct visualization of the embryo/fetus in the first trimester.
  • The technique facilitates identification of developmental milestones.
  • Feasibility of accessing human embryonic circulation via embryoscopy was established.

Conclusions:

  • Embryoscopy is a promising new technology for early pregnancy assessment.
  • It enables diagnosis of structural anomalies and monitoring of development.
  • Future applications may include targeted embryonic/fetal interventions like gene therapy.
