A subset of men with erectile dysfunction have an underlying neurologic or neurodegenerative condition which directly causes their impairment. The authors briefly discuss the interplay of the CNS, peripheral nervous system and corporal bodies of the penis integral to normal erectile function and how these interactions are disrupted in the setting of various neurologic conditions. Effective therapies for these patients exist in a variety of different forms to include oral or injectable drugs and even surgery. Future treatment strategies will focus on the improvement of existing therapies as well as the invention of new long-term therapeutic options.

Background: Erectile dysfunction (ED) is characterized by the inability to achieve or maintain penile erection sufficient for intercourse. While previous research suggests a potential link between ED and prostate pathologies, the association between benign prostatic hyperplasia (BPH), prostatitis, prostatic cancer (PCa), and ED remains to be elucidated.
Methods: Data from participants (40-80 years, n=2225) were extracted from the NHANES 2001-2004 for this observational study.

Background: Cavernous nerve injury-induced erectile dysfunction (CNI-ED) is a common complication following radical prostatectomy and severely affects patients' quality of life. The mitochondrial impairment in corpus cavernosum smooth muscle cells (CCSMCs) may be an important pathological mechanism of CNI-ED. Previous studies have shown that transplantation of human adipose derived stem cells (ADSC) can alleviate CNI-ED in a rat model.
