Cleavage and Blastulation01:33

Cleavage and Blastulation

45.3K
After a large-single-celled zygote is produced via fertilization, the process of cleavage occurs while zygotes travel through the uterine tube. Cleavage is a mitotic cell division that does not result in growth. With each round of successive cell division, daughter cells get increasingly smaller.

    Area of Science:

    • Embryology
    • Artificial Intelligence
    • Medical Imaging

    Background:

    • Blastocyst morphology assessment is critical for in vitro fertilization (IVF) success.
    • Current deep learning methods often provide qualitative, rather than quantitative, blastocyst evaluations.
    • Ranking blastocyst quality using qualitative assessments presents significant challenges.

    Purpose of the Study:

    • To develop a quantitative method for evaluating blastocyst quality using deep learning.
    • To improve the precision of blastocyst quality assessment for IVF procedures.
    • To introduce a regression network with a soft attention mechanism for this purpose.

    Main Methods:

    • A regression neural network combined with a soft attention mechanism was proposed.
    • The network generates a continuous score for precise blastocyst quality evaluation.
    • An attention module identifies and localizes regions of interest (inner cell mass) in blastocyst images.

    Main Results:

    • The proposed regression network quantitatively evaluates blastocyst quality.
    • The soft attention mechanism accurately localizes the inner cell mass (ICM).
    • The method demonstrated superior performance compared to traditional classification-based networks.

    Conclusions:

    • The developed deep learning model provides a more reliable and accurate quantitative assessment of blastocyst quality.
    • The visualized attention maps enhance the interpretability and trustworthiness of the network's predictions.
    • This approach offers a significant advancement for selecting optimal blastocysts in IVF treatment.
