Background: Erectile dysfunction and lower urinary tract symptoms, from benign prostatic hyperplasia and bladder neck obstructions, are prevalent in men and associated with an increased risk of cardiovascular diseases. Phosphodiesterase-5 (PDE-5) inhibitors, such as tadalafil and sildenafil, are used to treat erectile dysfunction and may also offer cardiovascular benefits due to their vasodilatory effects. This study evaluates the impact of these PDE-5 inhibitors on all-cause mortality, cardiovascular disease, and dementia in middle-aged men with erectile dysfunction and lower urinary tract symptoms over a 3 year follow-up period.
Methods: This longitudinal study analyzed data from 50 million US men using the TriNetX database. Men at least 40 years of age prescribed tadalafil or sildenafil after an erectile dysfunction diagnosis, or tadalafil after lower urinary tract symptom diagnoses, from 2004 to 2021 were included. Three-year outcomes assessed included all-cause mortality, cardiovascular disease, and dementia, comparing men on PDE-5 inhibitors to those not on these medications. Propensity matching was performed for demographics and eight pre-existing conditions.
Results: The final cohort included 509,788 men with erectile dysfunction and 1,075,908 with lower urinary tract symptoms. Tadalafil and sildenafil were associated with significantly reduced risks of all-cause mortality (RR 0.66/0.76), myocardial infarction (0.73/0.83), stroke (0.66/0.78), venous thromboembolism (0.79/0.80), and dementia (0.68/0.75) in erectile dysfunction patients, with tadalafil showing more significant benefits. In lower urinary tract symptom patients, tadalafil was similarly associated with reduced mortality, cardiovascular disease, and dementia.
Conclusions: In conclusion, tadalafil and sildenafil use in erectile dysfunction patients reduced mortality, cardiovascular disease, and dementia risks, with tadalafil providing more benefits. Tadalafil also conferred similar benefits to patients with lower urinary tract symptoms.

Background: Some studies suggest a potential association between plasma lipidome and erectile dysfunction (ED), but the underlying mechanism and whether circulating inflammatory proteins act as mediators remain unclear. The purpose of this study was to investigate the potential causal relationships between plasma lipidome, inflammatory proteins, and ED.
Methods: Plasma lipidome, circulating inflammatory proteins, and ED cases were identified based on the summary data from several large-scale genome-wide association studies (GWAS).

Background And Purpose: The prevalence of sequelae following rectal cancer (RC) treatment is high. We investigate the prevalence and temporal change in sexual dysfunction among male RC patient, along with their counselling and treatment needs and associations between sexual dysfunction and clinical factors. Patient/materials and methods: Patient-reported outcome measures were completed 3 and 12 months after RC surgery.

This study assessed the economic impact of reducing one postoperative visit following inflatable penile prosthesis (IPP) implantation. Scenario analyses were used to model the effects of eliminating one 30-min IPP postoperative visit from the expected 2.5 visits accounted for by the American Medical Association resource-based relative value scale data.

Utilizing network pharmacology and molecular docking, we evaluated the possible pharmacological mechanism of Danggui Sini Decoction (DGSND) for treating erectile dysfunction (ED). DGSND's chemical components and targets were found utilizing the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform (TCMSP). Disease-related genes associated with ED were identified through GeneCards, OMIM, TTD, DrugBank, and DisGeNET databases.

Background: Benign prostatic hyperplasia (BPH) is a common disease in middle-aged and elderly men, and its etiology is not completely clear. Late-onset hypogonadism (LOH) is a relatively common disease in the aging process of men. BPH is often accompanied by varying degrees of LOH, and the pathogenesis and progression of the two diseases are related.
