Is it true that a female's eggs are created during embryonic development?
Yes. Evidence from developmental biology confirms that female germ cells and ovarian structures form during embryonic and fetal development.
Verdict: SUPPORTED · 5 sources for, 0 against · Last checked
The analysis
The retrieved papers consistently discuss human and animal fetal ovarian development, primordial germ cells, and oogenesis occurring during embryonic/gestational stages. There is no evidence refuting the claim.
Evidence for · 5
Discusses how the in utero stages of ovarian development define reproductive capacity and how fetal exposure affects germ cells.
