Introduction: Erectile dysfunction (ED) is defined as the persistent inability to achieve and maintain an erection status sufficient to permit satisfactory sexual performance. Current evidence suggests that diabetes mellitus erectile dysfunction (DMED) is one of the leading causes of ED which remains a difficult condition to manage because of its complicated pathophysiological mechanisms. Recently, stem cell therapies have been added to the therapeutic treatment options for ED. Stem cells derived from adipose tissue are now considered an alternative approach to DMED with preliminary studies demonstrating their capability of promoting endothelial cell, smooth muscle cell, and cavernous nerve regeneration.
Aim: We will review the epidemiology and pathophysiology of ED, rat models, and adipose-derived stem cell (ASC) therapy and its effects.
Methods: The relevant literature and contemporary data, using keywords "adipose-derived stem cells and diabetes erectile dysfunction," were reviewed.
Main Outcome Measure: The main outcome measure was the evidence supporting the association between ASCs, diabetes ED, and rat model.
Results: ASCs can restore erectile function of DMED rats by promoting vascularization and neuralization of corpus cavernosum. They can also inhibit fibrosis and inflammation and protect smooth muscle cells.
Conclusion: ASCs have achieved satisfactory therapeutic effects in rat models of ED, but effectiveness and safety of their application in clinical research remain to be determined.

Background And Purpose: We lack population-based data on the use and effectiveness of phosphodiesterase- 5inhibitors (PDE-5Is) in post-radiotherapy long-term prostate cancer survivors (PCaSs). In this cross-sectional survey performed 9 years after curative radiotherapy we explored PDE-5I use and the drugs'effectiveness in 1,092 nine-year PCaSs responding to the sexual items of EPIC-26. The findings from PCaSs were compared to those from 2,847 age-similar men from the general population (Norms).

Pharmacists have often been viewed as the last line of defence against prescription errors in traditional care models. Although a large number of chronic care patients are using telehealth services to increase their access to continuous care, researchers have yet to investigate prescription safety in such settings in Australia. The absence of this literature is particularly concerning in the context of the Australian Government's admission in a 2024 report that the national health system has not adequately addressed the World Health Organization's 'Medication without harm' objective.

Sildenafil is used to treat erectile dysfunction and pulmonary arterial hypertension but is often illicitly added to energy drinks and chocolates. This study introduces a lateral flow strip test using aptamers specific to sildenafil for detecting its illegal presence in food. The process involved using graphene oxide SELEX to identify high-affinity aptamers, which were then converted into molecular gate structures on mesoporous silica nanoparticles, creating a unique signaling system.

Implantation of inflatable penile prosthesis should be considered as a definitive treatment of erectile dysfunction. However, the sole procedure might not allow for optimal dimensional and functional outcomes. The aim of this study was to systematically review the literature and present the findings on the optimal choice of perioperative methods, surgical techniques, and pharmacotherapy to improve penile length, curvature, and erectile function.
