Are you getting this info off of his profile? Cause this is what I got: "As a child, the boy was abducted by Orochimaru and became one of sixty children that were his test subjects. They were injected with the First Hokage's DNA in the hopes that they could replicate the First's ability to use Wood Release. Orochimaru later abandoned the experiment, believing that none of them had survived. In actuality, this boy was the lone survivor and found himself endowed with an unquantified Wood Release and likewise the First's abilities to control tailed beasts." There was also anime-only info following that going into detail of the event.
