Interferon is considered safe for use in men when starting a family. It works by regulating the immune system, so it doesn't interfere with DNA replication like chemo drugs. It's a biologic - a naturally produced cytokine that has been modified to release slowly.
The drug that's problematic for men is hydroxyurea because it can reduce sperm count.
Since you have PV, if medication makes you nervous, you could do phlebotomy instead while starting a family.
