Mr. Peter Thompson:

Selective reduction is covered by the same clauses, however there is a subsection on the data collection form which asks whether an individual case was a selective reduction. The problem is that selective reduction comes with a risk. When one performs a selective reduction, it can cause the whole pregnancy to miscarry. One ends up having a discussion with the woman on which option presents the lower risk. In a case where there is a baby who is very unlikely to survive and another who seems to be completely normal, and where it is unlikely that either will be born alive if the pregnancy is continued, a selective reduction could decrease the chance of the normal baby dying. However, there will be as much as a 15% risk of miscarriage of the normal baby at the time the selective reduction is carried out.
