Abstract:
Objective To explore the effects of aging on NO cGMP pathway and sexual hormone in penile tissue of different age rats. Methods The nitric oxide(NO) and cyclic guanosine monophosphate(cGMP) contents, nitric oxide synthase(NOS) activity in penile tissue and testosterone(T) and luteinizing hormone(LH) contents in blood of rats of different ages(2, 8, 16 and 24 months) were detected. Results With age increasing, ① The NO content of penile tissue firstly rose(8 months, the highest ) then dropped (24 months, the lowest), being the same as the variation of NOS( P
