1. The cell cluster, immediately post-insemination of the ovum in a Petri dish in a fertility laboratory, prior to implanting the fertilised ovum in the womb. |
2. The cell cluster, frozen and preserved in a fertility laboratory that can be thawed and potentially implanted in the womb. |
3. The cell cluster, immediately after fertilisation of the ovum and the sperm inside the female body, prior to the implantation of the fetus in the womb and prior to the delay in menstruation (Week 2 of pregnancy). |
4. The implantation of the fetus in the womb walls and the delay in menstruation. |
5. Fetal heartbeats can be tracked (Week 8 of pregnancy). |
6. Appearance of human morphology – the fetus acquires more or less human features (Week 10 of pregnancy). |
7. All functional systems exist and the pregnant woman is beginning to feel the movements of the fetus. At this stage, the fetus undergoes amniocentesis (Weeks 16–20 of pregnancy). |
8. The stage of viability, meaning that the fetus can survive independently outside of the mother's body (Weeks 23–24 of pregnancy). |
9. It is possible to estimate the fetus' weight at birth (Week 32 of pregnancy). |
