This week's programme in the series on Man and Science Today.

It takes only a few weeks for the embryo in the mother's womb to take on the recognisable features of a human being. What factors in the mother's life influence this development in the womb? It is only recently that the full significance of the foetus, as a patient who can be medically cared for, has been realised.
Can emotional stress on the mother permanently affect her child? Can genetic abnormalities be recognised before birth? And if so what medical and moral decisions should be taken?
One baby in 20 is born handicapped, damaged at some stage during its development in the womb. Are some of these tragedies avoidable?
This programme won the Society of Film and Television Arts Mullard Award. It deals with research of fundamental importance which could change the direction of medical advance.
