Question: To ask the Secretary of State for Health and Social Care, pursuant to the answer of 9 October 2025 to Question 76643 on Primodos, whether his Department plans to consider scientific evidence from Aaron. P. Adam et al (2026) titled Recurrent Constellations of Embryonic Malformations: Teratogenicity Linked to Transient Hypoxia and Hormone Pregnancy Tests Agrees With RCEM and Suggest a Reactive Oxygen Species Pathogenesis, as part of its review of the evidence on hormone pregnancy tests.

P. Adam et al, presents any new scientific evidence and will act as appropriate.
