War for survival
Pregnancy is a brutal, yet magical war for survival. Sperm face deadly barriers, the embryo infiltrates the mother's body, and the placenta becomes a new organ to steal resources, all while balancing the interests of mother and child.
- ⚔️ Sperm face a gauntlet of acidic environments, protein nets, and immune cells, with only a few hundred of millions reaching the egg.
- 🦠 The embryo implants by releasing genetic material to 'brainwash' uterine cells, and the placenta develops as a temporary organ derived from the embryo's cells.
- 🤝 The mother's immune system is suppressed and even co-opted to protect the embryo, with some embryonic cells spreading throughout the mother's body.
- ⚖️ Fetal genes prioritize survival at all costs, sometimes leading to gestational diabetes in the mother as the fetus demands more resources.
