to assess whether administration of gnrh-a by constant subcutaneous infusion will also lead to greater inhibition of gonadal function , we administered either 20 or 200 micrograms of d ( nal2 ) 6gnrh ( gnrh-a ) to two groups of normal male volunteers , either by a single daily injection or constant subcutaneous infusion through a portable infusion pump , for 28 days .
