[Examination of the fertility of patients with malignant testicular cancer at the time of orchiectomy. The question of the opinion on cryopreservation].

Semen analyses from 29 patients with testicular tumours were done, 19 were examined before and after orchidectomy but before any other treatment. There was no evident difference in both of these examinations. Therefore it is possible to obtain enough time for cryopreservation, because the stricken patients can be first treated by unilateral orchidectomy without loss in quality of the semen. Hendry et al. (1983) accepted for sperm freezing only samples with more than 10 mill/ml spermatozoa and more than 30% motility. 17 of our 29 patients (58.6%) fulfilled that condition. Thus, in more patients cryopreservation can be considered.
