Modulation of endothelial calcium-activated K(+) channels has been proposed as an approach to restore arterial endothelial cell function in disease. We hypothesized that small-conductance calcium-activated K(+) channels (KCa2.3 or SK3) contributes to erectile function. The research was performed in transgenic mice with overexpression (KCa2.3 (T/T(-Dox))) or down-regulation (KCa2.3 (T/T(+Dox))) of the KCa2.3 channels and wild-type C57BL/6-mice (WT). QPCR revealed that KCa2.3 and KCa1.1 channels were the most abundant in mouse corpus cavernosum...

Potassium channels (K(+)Ch) in corpus cavernosum play an important role in the regulation of erection. Nitric oxide (NO) acts through opening of K(+)Ch leading to hyperpolarization and relaxation. Aim : This study aims to update knowledge about the role of voltage-gated K(+)Ch (KV) channels in erectile machinery and investigate their role in the control of NO action &/or synthesis in the corpus cavernosum. Methods : Tension studies using isolated rabbit corpus cavernosum (CC) strips and rat anococcygeus muscle were conducted...

Erectile dysfunction (ED) is one of the most common disorders in male and is often associated with other age-related comorbidities. The aging process affects the structural organization and function of penile erectile components such as smooth muscle cell and vascular architecture. These modifications affect penile hemodynamics by impairing cavernosal smooth muscle cell relaxation, reducing penile elasticity, compliance and promoting fibrosis. This review aims to identify the mechanisms of ED in the penile aging process in experimental and clinical data...

INTRODUCTION: Tissue engineering of corporal tissue is a new development in otherwise untreatable erectile dysfunction and in urethral reconstructions to treat hypospadias or severe urethral stricture disease. Multiple complications can arise with the current treatments, whereas engineered tissue, if well vascularized and existing of autologous cells, may lead to better results. The aim of this review was to provide an overview of literature on cell seeded based tissue engineering of corporal penile tissue...

The pathophysiology of erectile dysfunction post radical prostatectomy is not clearly clarified, and the low efficacy of traditional PDE5i treatment remains a major complaint in contemporary practice. This study aimed to demonstrate phenotypic modulation in bilateral cavernous nerve injury (BCNI) rats within 7 days, and subsequently validate gene therapy with Myocardin (Mycod) by maintaining a contractile phenotype in corpus cavernosum smooth muscle cells. Initially, 36 male rats were randomly divided into BCNI and negative control (NC) groups for histological and phenotypic molecular measurements at 3, 5, and 7 days...

BACKGROUND/AIMS: Transforming growth factor-β1 (TGF-β1) plays important roles in penile corporal fibrosis and veno-occlusive dysfunction (CVOD). Angiotensin II (Ang II) is critically involved in erectile dysfunction, and blocking of Ang II is more important than inhibition of TGF-β in non-penile tissue fibrosis. However, the role of Ang II in corporal fbrosis and CVOD in a diabetic condition has not been investigated. METHODS: Diabetic rats were treated with sildenafil or losartan (an Ang II antagonist) alone or in combination...

BACKGROUND: Penile corpus cavernosum is an extremely vascularized tissue and cavernosal smooth muscle tone is regulated by the balance between contractile and relaxant factor. We investigated the possible role of arachidonic acid/cyclooxygenase cascade, phosphodiesterase IV (PDEIV) and Rho-kinase in exogenous hydrogen sulfide (H2S)-induced relaxation in mouse corpus cavernosum. METHODS: The relaxant response to H2S (NaHS as exogenous H2S; 1-1000μM) were obtained in isolated mouse corpus cavernosum tissues which pre-contracted by phenylephrine (5μM)...

The transient receptor potential cationic channel ankyrin 1 (TRPA1) is a channel protein assumed to act in various human tissues as mechano- and pain sensor and play a role in neurotransmission. The expression of TRPA has already been investigated in the human prostate and urethra, however, only very few studies have addressed the expression and distribution in the male and female genital tract. The present study aimed to investigate by means of immunohistochemistry (double-labeling technique, laser fluorescence microscopy) in the human clitoris and penile erectile tissue the localization of TRPA1 in relation to nNOS, the vasoactive intestinal polypeptide (VIP) and vesicular acetylcholine transporter (VAChT)...

We present here a rare case of rupture of tunica albuginea and corpus cavernosum, in the site of a Peyronie's plaque, which happened in a 61- year-old man during a vacuum cleaner masturbation. Ultrasound study showed an irregular hyperechoic defect at the cavernosal rupture site in correspondence of the Peyronie's plaque. The hematoma was evacuated, partially plaque excised, and the tear repaired. Ultrasonography is an ideal technique for evaluating patients with penile trauma and can be routinely used in an emergency...

SIGNIFICANCE: The endogenous hydrogen sulfide (H2S) pathway produces an array of biological effects that vary depending on the bodily region. In addition, the H2S pathway's relevance often changes depending on a healthy or disease state. There is abundant evidence pointing to a key role for this pathway in male and female genito-urinary diseases, suggesting it as a possible target for new therapeutic approaches. Recent Advances: The tissue-specific localization of the H2S enzymes in the genito-urinary tract has allowed for a better understanding of its role in the body's pathophysiology...

Emerging evidence indicates that aldosterone and mineralocorticoid receptors (MRs) are associated with the pathogenesis of erectile dysfunction. However, the molecular mechanisms remain largely unknown. In this study, freshly isolated penile corpus cavernosum tissue from rats was treated with aldosterone, with or without MRs inhibitors. Nuclear factor (NF)-kappa B (NF-κB) activity was evaluated by real-time quantitative PCR, luciferase assay, and immunoblot. The results demonstrated that mRNA levels of the NF-κB target genes, including inhibitor of NF-κB alpha (IκB-α), NF-κB1, tumor necrosis factor-alpha (TNF-α), and interleukin 6 (IL-6), were higher after aldosterone treatment...

Median raphe cysts are congenital lesions that typically have a superficial appearance. We present a very unusual case of a deep perineal mass in a six-year-old boy. The lesion extends into the corpus cavernosum, suggesting that the anomaly was an early embryological event. Histopathological features are consistent with an epidermoid type of median raphe cyst.

The present study was aimed to examine whether icariin, a traditional Chinese medicine, could improve therapeutic effects of adipose derived mesenchymal stem cells (ADSCs) for diabetes-associated erectile dysfunction (DMED). DMED were induced in rats by intraperitoneal injection of streptozotocin and confirmed by erectile function measurement. Then, rats of diabetic ED were randomly divided to receive the treatment of saline, ADSCs, icariin or ADSCs combined with icariin respectively. Compared with the treatment by ADSCs or icariin alone, intracavernosum injection of ADSCs combined with the following daily gastric gavage of icariin significantly augmented the value of ICP and ICP/MAP (p<0...

BACKGROUND: Recurrent priapism secondary to sickle cell trait in an African-American male has been reported in the literature. A common treatment for these low-flow priapism cases is aspiration and injection of the corpus cavernosum with a sympathomimetic agent. We report a rare complication not described previously in the literature of ST-elevation myocardial infarction (STEMI) and cardiogenic shock in a 29-year-old male with sickle cell trait undergoing a routine detumescence procedure...

Penile fracture is a relatively rare condition arising from a rupture of the corpus cavernosum. In the western world, it is most commonly associated with sexual intercourse. We hereby, report a rare case of accidental, non-masturbatory, self-inflicted penile fracture. It was diagnosed promptly based on clinical assessment, confirmed radiologically and managed surgically, resulting in a good long-term clinical outcome. Our case highlights the importance of maintaining a high index of suspicion to diagnose this rare condition, even in the absence of a typical mechanism of injury, in order to ensure that such an injury is not missed...

Molecular mechanisms of the beneficial effects of angiotensin-(1-7), Ang-(1-7), in diabetes-related complications, including erectile dysfunction, remain unclear. We examined the effect of diabetes and/or Ang-(1-7) treatment on vascular reactivity and cyclic guanosine monophosphate (cGMP) phosphodiesterase (PDE) in corpus cavernosum. Male Wistar rats were grouped as (1) control, (2) diabetic (streptozotocin, STZ, treated), (3) control + Ang-(1-7), and (4) diabetic + Ang-(1-7). Following 3 weeks of Ang-(1-7) treatment subsequent to induction of diabetes, rats were sacrificed...
