If the tumor is less than 2 cm in size you can use partial orchidectomy instead of radical. but if you suggest to do that frozen is benefical. because even in azospermic testis you can find small islands of sperm.

Dear Alireza.

Thanks for your suggestion.

We´ve done radical orchidectomy, saving tissue adjacent to the tumor (Seminoma)

We don´t do partial orchi.
