Age of Viability


5 months, 1 week

From The Biology of Prenatal Development.Buy Now

Script: Στις 21 με 22 εβδομάδες μετά τη γονιμοποίηση, τα πνευμόνια αποκτούν την ικανότητα να αναπνέουν. Αυτή θεωρείται η ηλικία της βιωσιμότητας επειδή η επιβίωση έξω από τη μήτρα είναι εφικτή για μερικά κυήματα.

All ages referenced to fertilization, not last menstrual period. One month = 4 weeks.
