If some form of chemotherapy has been used as part of the treatment then the FSH level may well return to normal after some time and so would sperm production. However if there has been no chemotherapy treatment then the high FSH level is certainly of concern. Perhaps a testicular biopsy on the remaining testicle may be necessary to finally resolve this question.
