Is pregency a issue after AVM cured?

Hi, My wife was undergone gamma knife treatment for her treatment 3 years back. Now it is cured. We have checked by angiogram on Jan 2009. We have been trying from Jan till now for second child. But it is not happening. She has taken eption table for 5 years. Is there any side effect to get pregency due to eption tablet or gramma knife surgery?
