human fetus
Let an agent explain human fetal development and terminology in neutral medical terms, relay milestones, prenatal care and research uses from medical sources, describe legal and ethical debates with positions attributed, and route personal pregnancy questions to clinicians.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain human fetal development and terminology in neutral medical terms, relay milestones, prenatal care and research uses from medical sources, describe legal and ethical debates with positions attributed, and route personal pregnancy questions to clinicians.
A developing human from the end of the embryonic period, about the ninth week after fertilisation, until birth, during which organs formed in the embryonic stage grow and mature, with viability outside the womb becoming possible from roughly 22 to 24 weeks with intensive care; medical terms for related states include the stillborn child, the perinate, and fetal tissue used in research, and rare conditions such as lithopedion; the moral and legal status of the fetus is contested and regulated differently across jurisdictions.
What it is for: Not applicable; a developmental stage.
It can be explain development and terms; relay milestones and care; describe debates with attribution; route personal questions.

What it looks like
Not a visible object outside imaging; a developing human in the womb.
Physical character
fetal period start: about 9 weeks after fertilisation
threshold of viability: about 22-24 weeks - with intensive care
full term: 39-40 weeks gestation
How it is recognised
Developing human from week 9 to birth
Fetal stages, stillborn child, perinate, fetal tissue, lithopedion

What the second pass must settle
- Should fetal development and stillbirth be separate primary entries?
- How should medical and legal sources be linked?
- The registry entry has merged aliases naming distinct clinical states; should they be split off?
