Correct answer: A — Counsel that valproate can impair male fertility and that emerging evidence suggests possible developmental risks; advise specialist review

While the Valproate Pregnancy Prevention Programme primarily targets women of childbearing potential, emerging evidence and MHRA guidance from 2024 extends precautionary advice to males taking valproate. Studies suggest possible associations between paternal valproate use and neurodevelopmental disorders in offspring, and valproate can impair sperm parameters. The patient should be referred for specialist review to discuss risks and consider alternative antiepileptic drugs before conception.
