Morphology

in + utero

The phrase is a literal locative composition of 'in' + 'utero' meaning 'inside the uterus', so the overall meaning is directly derivable from the parts. Although 'utero' is a medical/Latin form and may be unfamiliar to some B1 learners, if they know this constituent (or its cognate 'uterus'/'útero' in other languages) the expression is transparent.

Etymology

The phrase in utero comes from Latin and literally means 'in the womb'. So today doctors use in utero to say that something happens while a baby is still inside the mother, or 'before birth'.
