Abstract

Surgery in germ cell tumors of the testis (TGT) may result in andrological disorders, both after orchiectomy and after retroperitoneal lymphadenectomy (RPLND). Bilateral orchiectomy suppresses both testicular functions: exocrine and endocrine. In selected cases with bilateral TGT (metachronous/synchronous), or in the case of TGT in monorchid patients, partial orchiectomy (enucleation of the tumor) can preserve both functions with a low risk of relapse in residual testicular parenchyma, in the absence of intraepithelial neoplasia (TIN). In cases of TIN and normal testosterone levels (80%), the fertility is maintained in 50% of patients. In these cases the use of radiotherapy on the residual testicular parenchyma can prevent the future development of invasive cancer, though compromising the hormonal function. The RPLND (open or laparoscopic) can produce major side effects, such as retrograde ejaculation. Knowledge of the adrenergic fiber retroperitoneal neuroanatomy enables to implement a "nerve sparing" surgery with an almost total reduction of this serious side effect, but that option is only available in few centers of excellence. Semen cryopreservation has become a common practice performed before any treatment that might impact on the andrological function of patients.
