This series was developed in co-operation with a German midwifery school and is composed of 8 life-size models and one enlarged model. It illustrates the human development from the 4th week to the 24th week. All the main anatomical structures of the uterus and embryo/fetus are well represented and explained on the manual.

The models show:
- Embryo, 4 weeks, enlarged
- Embryo in uterus, 4 weeks
- Embryo in uterus, 8 weeks
- Fetus in uterus, 12 weeks
- Fetus in uterus, 16 weeks
- Fetus in uterus, transverse presentation, 24 weeks
- Twins in uterus, 2 separate placentas, 16 weeks
- Twins in uterus, 1 common placenta, 16 weeks

Each model is mounted on a removable stand. Some models allow removable of the fetus.
