For male patients in chronic phase CML on a TKI and not yet in a MMR, is there a preferred amount of time spent in a MMR before discontinuing TKI therapy to conceive or bank sperm ?   

Drug information indicates a patient may need 3-4 months off TKI. This seems like a long time off drug. Would a MMR of a certain duration make it less risky to be off of therapy?
