[Onco-TESE and testicular cancer].

Fertility preservation is essential before cancer treatment. When ejaculated sperm preservation is not possible, testicular tissue can be surgically collected by Onco-TESE technic (Oncological Testicular Sperm Extraction) to isolate sperm. We report on our experience with Onco-TESE in testicular cancer patients at the Rouen University Hospital.

Retrospective study including all pubescent men, treated for testicular cancer, uni- or bilateral, before any carcinological therapy, who have undergone Onco-TESE at the Rouen University Hospital. Fragment weight, detection of sperm or its precursors were analysed. A histological interpretation of the testicular tumor was carried out. For each positive sample, straws were kept at the French Sperm Bank.

Twenty-four patients had an Onco-TESE: 58.34% severe sperm alteration (SSA) and 41.36% sperm collection failure (SCF), between 1996 and 2019. The mean age was 26.6 (±5.29) years. The mean procedure and length of stay were 71minutes (±30.7) and 3.75 days (±2.83), respectively. The rate of positive testicular biopsies (TB) was 58.33% overall and 66,67% in the case of TB on tumour testis. One patient had a Clavian-Dindo III complication. The mean number of straws preserved per patient was 14.28 (±15.34) for 7.14% use.

Our results seem to confirm that Onco-TESE is an effective solution for preserving fertility in men with testicular cancer in cases of SSA or SCF.
