Cryopreservation of human sperms may insure fertility before exposure to gonadotoxic agents.

ABSTRACT

A retrospective study was done on three hundred patients complaining of either azoospermia or severe oligospermia. Their ages ranged between nineteen to forty two with a mean of 29 +/- 1 [years]. There were thirty six patients with history of exposure to different gonadotoxic agents such as radiotherapy, chemotherapy as well as mumps infection. Also, there were high FSH level, hypospermatogenesis and complete absence of spermatogenesis. The study showed the marked effect of these gonadotoxic agents on fertility. So, the study recommend cryopreservation of sperms samples for any person who may be exposed to these agents or any surgical manoeuvre which may affect his fertility
