Objective:
To investigate the prevalence of erectile dysfunction (ED) in men with pre-diabetes.
Methods:
This study included 500 men with impaired fasting glycaemia (IFG), 500 with impaired glucose tolerance (IGT), and another 500 with normal blood glucose (NBG), all from Lanzhou. We conducted a questionnaire investigation among the subjects using the International Index of Erectile Dysfunction 5 (IIEF-5).
Results:
The prevalence rates of ED in the IFG, IGT, and NBG groups were 14.8%, 29.2%, and 33.2%, respectively. After controlling for age, nationality, occupation, education, income, obesity, and blood pressure, the incidence rate was markedly higher in the IFG and IGT than in the NBG group (29.2% and 33.2% vs 14.8%, P <0.05), but showed no statistically significant difference between the IFG and IGT groups (P >0.05).
Conclusions:
The prevalence of ED is higher in men with pre-diabetes than in those with normal blood glucose in Lanzhou.

pre-mRNA Processing
Once about 20-40 ribonucleotides have been joined together by RNA polymerase, a group of enzymes adds a “cap” to the 5’ end of the growing transcript. In this process, a 5’ phosphate is replaced by modified guanosine that has a methyl group attached to it (7-Methyl...
Pathophysiology of Diabetes
Type 1 diabetes is characterized by autoimmune-mediated destruction of pancreatic β cells, with environmental factors potentially triggering this process in genetically susceptible individuals. Despite many not having a family history, certain genes increase susceptibility,...
