Benefit of sperm freezing before radical orchiectomy.

A patient with a unilateral testis tumour who had been treated with radical orchiectomy was referred to our centre. He was oligospermic before orchiectomy and needed chemotherapy because of abnormal tumour markers after the aforementioned operation. He did not have any sperm suitable for freezing. Because of a lack of information about the spermatogenic abilities in the other testis, it is advisable to freeze sperm prior to orchiectomy at least in patients with semen analysis disorders.
