Neferneferuaten-tasherit's age is the first objection often raised. She is thought to have been about ten at the time of Akhenaten's death, but Allen suggests that some daughters may have been older than generally calculated based on their first depicted appearance. Meketaten is believed to have been born about year 4 when is she first depicted. If that is the case, she would only have been ten or eleven when she died in childbirth around year 14, which is several years shy of the age when girls typically become able to conceive at age 13 (Akhenaten and his daughters may have suffered from a hereditary genetic condition called aromatase excess syndrome, which resulted in gynecomastia in males and premature sexual development in females, making childbirth at 11 less improbable).
