Medical management of male infertility. 
The medical management of male infertility has a precise role to play.  Inappropriate use of drugs, apart from not promoting fertility, may actually predispose to infertility.  Gonadotoxic or gametotoxic drugs should be avoided if possible.  If potentially toxic drugs are used for a medical condition, suitable, less or non-toxic alternatives should be used.  Where medical management is not possible, instead of wasting time and money on expensive unproven therapies, early recourse to assisted reproduction must be sought.
