Why I can’t agree with the conclusions of the report on Primodos

Press/Media: Articles in 'The Conversation'


Campaigners have long argued that the hormone pregnancy test, Primodos, caused birth defects, but a UK government expert panel recently dismissed these claims.

So what evidence is there for the Commission on Human Medicines’ (CHM) conclusion? As it happens, not a lot. There were only a handful of studies looking at whether Primodos could harm the developing baby, and most are decades old. Some of these studies suggest that Primodos caused birth defects; some do not. But the limited number of studies, their age and the different tests used to assess the effect of Primodos on the embryo, makes it difficult to be 100% conclusive.

Campaigners, perhaps unsurprisingly, suggest a cover up.
