Given that nitrite is described to display antioxidant effects, we hypothesized that treatment with nitrite would exert antioxidant effects attenuating both reactive oxygen species (ROS) generation in the corpora cavernosa (CC) and ED induced by hypertension.
In case of severe curvature and preserved erectile function, plaque incision/excision (PIG/PEG) are advisable in order to maximize penile length, despite the risk of postoperative erectile dysfunction (ED), recurrent curvature, or penile shortening.
Sphingosine-1-phosphate (S1P) and S1P receptor 2 (S1PR2) are important factors regulating the Rho-kinase pathway, and understanding these factors may provide ideas for new therapeutic strategies for ED.
These results warrant future studies on the utility of measuring serum oestradiol in patients with erectile dysfunction and the use of aromatase inhibitors in patients with erectile dysfunction and elevated serum oestradiol.
The evaluation of men with ED requires a full medical and personally and culturally sensitive sexual history, a focused clinical examination, fasting glucose levels, a fasting lipid profile and, in select cases, a total testosterone level and a prostate-specific antigen test.
In adults, although its association with lipid levels is not evident, there is a significant relationship between the PCSK9R46L variant and markers of subclinical atherosclerosis, including IMT and ED.
These results suggest that impairment of the dopamine D2 receptor pathway in the basolateral amygdala may contribute to the development of nonorganic erectile dysfunction.
The results found that capillaries and vascular smooth muscle cell content reduced, and NgBR and ICAM-1 were elevated in rats with diabetic ED. si-NgBR relieved ED by decreasing penile corpus cavernosum smooth muscle systolic percentage and increasing erectile time and rate, intracavernous pressure (ICP)/mean arterial pressure (MAP) and diastolic percentage, improving the pathological changes and inhibiting cavernosum cell apoptosis. si-NgBR also resulted in the down-regulation of ICAM-1 and downstream SRC and PYK2 and promoted α-SMA expression.
Erectile dysfunction (ED) is frequently encountered in patients with arterial hypertension and there is a recent functional correlation between the expression of thermoreceptor channels TRPM8 (melastatin 8) and alterations in blood pressure in hypertension.
We performed a genome-wide association study of ED in 6,175 case subjects among 223,805 European men and identified one locus at 6q16.3 (lead variant rs57989773, OR 1.20 per C-allele; p = 5.71 × 10<sup>-14</sup>), located between MCHR2 and SIM1.
We aimed to assess whether: 1) ADMA and nitrite levels associated with ED risk and with symptoms intensity; and whether 2) DDAH1 and DDAH2 gene polymorphisms associate with changes in biochemical data, and with ED risk and symptoms intensity.
The results found that capillaries and vascular smooth muscle cell content reduced, and NgBR and ICAM-1 were elevated in rats with diabetic ED. si-NgBR relieved ED by decreasing penile corpus cavernosum smooth muscle systolic percentage and increasing erectile time and rate, intracavernous pressure (ICP)/mean arterial pressure (MAP) and diastolic percentage, improving the pathological changes and inhibiting cavernosum cell apoptosis. si-NgBR also resulted in the down-regulation of ICAM-1 and downstream SRC and PYK2 and promoted α-SMA expression.
Among men with type 1 diabetes not using antihypertensive medications, higher SBP is associated with increased risk of developing erectile dysfunction.
The extract from AWS cooked with/without shell interacted with phosphodiesterase-5 (PDE-5), arginase, angiotensin-I converting enzymes (ACE), and acetylcholinesterase (AChE); enzymes associated with erectile dysfunction (ED) and Fe<sup>2+</sup> -induced malonaldehyde (MDA) production in the isolated penile tissue.
Clarifying the Relative Impacts of Vascular and Nerve Injury That Culminate in Erectile Dysfunction in a Pilot Study Using a Rat Model of Prostate Irradiation and a Thrombopoietin Mimetic.
The results found that capillaries and vascular smooth muscle cell content reduced, and NgBR and ICAM-1 were elevated in rats with diabetic ED. si-NgBR relieved ED by decreasing penile corpus cavernosum smooth muscle systolic percentage and increasing erectile time and rate, intracavernous pressure (ICP)/mean arterial pressure (MAP) and diastolic percentage, improving the pathological changes and inhibiting cavernosum cell apoptosis. si-NgBR also resulted in the down-regulation of ICAM-1 and downstream SRC and PYK2 and promoted α-SMA expression.
