my significant other when through chemo

Christy
Hi everyone,
We are new to the TTC world, I haven't yet started ovulating since leaving BC but it really hasn't been long, I however have realized that my boyfriend is having a little anxiety about his fertility as he went through very highly doses of chemo 8 years ago, he survived osteosarcoma cancer which has a high mortality rate this the very strong chemo? Any one here with similar story's where TTC was successful? He is more than willing to go for fertility tests later but is obviously hoping that won't be necessary
