Why embryo development can stop
Embryo growth is affected by oocyte competence, sperm DNA integrity, chromosomal balance, and culture conditions.
Not a single-cause event
Embryo arrest does not automatically mean treatment failure. It often signals a need to adjust stimulation, lab strategy, or transfer planning.
How clinics respond
Good centers review cycle data deeply, identify probable bottlenecks, and redesign the next protocol instead of repeating the same approach.
