I don't really know the question u are asking all I understand is sperm so on that note I'm gonna ask if ur question has anything to do with donating if it does I would absolutely ask ur doctor about that B4 u do anything! I was wanting to donate blood cuz my blood is excellent for leukemia cancer patients ( go figure huh) anyway cuz of the blood cancer I have I will NEVER EVER be able to donate again just for the fact there could be a very very small chance I have cancer somewhere hiding in my body( I have a high chance of it returning (cuz it's not curable) it will only be in remission I'm very happy I asked B4 giving so PLEASE ask B4 doing anything GOD BLESS U AND EVERYBODY 😇🙏

I’m sure he can, but just check with the Doctor.

Before treatment they freeze him the sperm but I wish to know if he can have natural

I would think the oncologist would have discussed this topic before he started treatment.
While I was in the hospital receiving my chemo I had a couple visit me from a church . They did not know my diagnosis. We found out their son had Burkett's when he was 19 & was now 40 , married with 2 children!
