Is ex vivo microdissection testicular sperm extraction indicated for infertile men undergoing radical orchiectomy for testicular cancer? Case report and literature review

摘要

Objective To report a case of an infertile man with nonobstructive azoospermia who underwent simultaneous radical orchiectomy for testicular cancer and testicular sperm extraction (TESE) for preservation of fertility. Design Case report and literature review. Setting University teaching hospital. Patient(s) A couple being treated for infertility. Intervention(s) Radical orchiectomy with simultaneous TESE. Main Outcome Measure(s) Sperm retrieval, histologic evaluation of archived testicular pathology slides. Result(s) We retrieved 20 spermatozoa from the multiple random TESE samples obtained at radical orchiectomy. Histologic evaluation of the archived testicular pathology slides revealed that the testis contained several foci of active spermatogenesis, suggesting that a significantly greater number of spermatozoa would likely have been retrieved had a microdissection TESE been performed instead of the multiple TESEs. Conclusion(s) We propose that microdissection TESE should be considered the preferred sperm retrieval technique at the time of radical orchiectomy in men with coexistent nonobstructive azoospermia and testicular cancer.
