2. human Chorionic Gonadotropin (hCG) from placenta
3. human Placental Lactogen (hPL) from placenta
4. oxytocin from maternal pituitary

Signals from fully developed foetus and placenta ultimately lead to parturition which requires the release of:
| 1. | Oxytocin from maternal pituitary |
| 2. | Oxytocin from foetal pituitary |
| 3. | Relaxin from the placenta |
| 4. | Estrogen from placenta |
