Conclusion
Performing TESE during radical orchiectomy provides a unique opportunity
to preserve fertility among single testis with testicular cancer
patients without causing additional physical damage. We successfully
performed sperm retrieval through Onco-TESE for azoospermia in
congenital single testis patient with a testicular cancer, and a child
birth following ICSI using cryopreserved testicular spermatozoa.
