It is an interesting time for this to come back up. We just had a scare about a possible pregnancy and the full 6 month window had not passed yet. I looked intyo everything I possible could and there is actually no link between infertility and birthdefects with Temodar that has been reported in recent literature. Our NO basically told us the same thing, but said to be on teh safe side give your body about 6 months to clear the drug.
We still plan on waiting a few more months, as that is what works for us, but there is little risk from what I can tell. the one study I did find was a case study of 6 women who became pregnant during treatment with temodar. They discontinued treatment and all went on to have healty uneventful pregnancies. While not a huge sample size, it is definitely reassuring for anyone considering this.
Of course we still haven't decided 100% simply due the chance of recurrence and having even more chaos to deal with if that were to happen. Hope this information can help anyone. I can find that paper again if someone is interested.
