My son was 6 and took 8 months of chemo, would he be sterile

Would a 6 year old become sterile after 8 months of cjemotherapy

Don't know. It's never a 100%

I took 6 months of chemo as well and I was told I was sterile. Lo and behold, 10 years later I gave birth to a beautiful baby boy.

You need to discuss this with his oncologist.
