Morphology
The phrase is a straightforward nominal compound: 'fertilization' (the event of egg and sperm fusing) + 'age' (time since origin), so a learner who knows both words can infer it means the age measured from fertilization. This compositional pattern is regular in English and mirrored in other languages, making the meaning immediately derivable rather than idiomatic.
Etymology
The term fertilization age comes from the simple idea of starting the clock when the fertilization — the meeting of egg and sperm — happens. That picture of counting the baby’s age 'from fertilization' rather than 'from the mother's last menstrual period' explains why the phrase means the embryo or fetus' age measured from that moment.
