RESUMEN
INTRODUCTION: The application of chemo- and radiotherapy results in good survival prognosis for young men with malignant tumors, but long-term gonadoxic effect has to be considered. In addition, malignant disease itself has a negative impact on spermiogenesis. AIM: The aim of the authors was to examine the spermiogenetic effect of the most common tumors occurring in the reproductive age in men: testicular cancer, Hodgkin disease and non-Hodgkin disease. METHOD: Spermiogram of men with testicular cancer (N = 68), Hodgkin disease (N = 37) and non-Hodgkin disease (N = 14) who were referred for sperm cryopreservation were analysed in the Reproductive Andrology Laboratory of the authors. RESULTS: Azoospermia was found in 11.8% of all patients (N = 119), while 58.8% of the patients had oligozoospermia even before the treatment. Sperm concentration of men with testicular cancer was significantly lower than those with lymphomas (32.8 M/mL vs. 24.9 M/mL, p = 0.03). There was no difference in sperm concentration between the Hodgkin and non-Hodgkin lymphoma groups. CONCLUSIONS: Spermiogenetic defect is more pronounced in men with testicular cancer than those with lymphomas. Cryopreservation before treatment for fertility preservation should be offered for all reproductive aged men with malignant disease, especially for those with testicular cancer.
