At present, the study of erectile dysfunction depends heavily on animal models, but the differences in anatomy and physiology of currently used animals make it difficult to exceed the limitations on the experiment. In order to make the results of experiments more applicable and beneficial to the public, it is essential to establish most suitable animal models for the study of the sexual function of humans. Moreover, a consensus has not yet been reached on the methods of detecting and evaluating the erectile function of animals, and therefore an informative and instructional summary of the existing methods seems even more necessary. This article discusses how to establish and evaluate the animal models of different types of erectile dysfunction.

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.

Background: Benign prostatic hyperplasia (BPH) is non-cancerous growth of the prostate gland which surrounds the urethra. For men with BPH who are older than 50, a prostatectomy is a common surgical procedure. Open prostatectomy is still more prevalent in regions with limited access to advanced surgical procedures like transurethral resection of the prostate and robotic-assisted laparoscopic prostatectomy.
