Leunbachs work helped launch a debate on abortion, which in 1937 brought the Danish parliament to pass Denmark's first abortion legislation, which reduced the penalty for induced abortion and gave better opportunities to let a woman have an abortion for health reasons.
Leunbachs virke var dog med til at starte en debat om abort, som i 1937 fik Rigsdagen til at vedtage Danmarks første svangerskabslov, som nedsatte straffen for illegale aborter og gav bedre muligheder for at lade en kvinde få en abort af sundhedsmæssige grunde.
