Key Ontogenetic Stages:

🧬 Biological Milestones Carnegie Stage 23

Primary organogenesis completed. Craniofacial features distinct; eyes rotate forward. Reflex movements (non-cortical) begin. Palate fuses, fingernails develop, intestines rotate into abdominal cavity.

📊 CDC Surveillance Distribution 93.1%

Reported abortions occurring at or before this gestational age:

Over 93% of all reported induced terminations in the United States occur within the first trimester ($\le 13$ weeks LMP). Only ~1% occur past 20 weeks.

🏥 Neonatal Survival Chance N/A (Pre-viable)

Expected survival if delivered now (High-Resource NICU):

Prior to 22 weeks, the pulmonary canalicular vascularization and alveolar surfactant machinery cannot sustain gas exchange outside utero.
