A meta-analysis of comparable data was performed using RevMan 5.0. Statistical heterogeneity between studies was assessed using the I 2 statistic. Pronounced heterogeneity was indicated by a P value ?0.05 and an I 2 value ?50%; in these cases, a randomized effects model was executed. A P value ?0.05 and I 2 ? 50 indicated no obvious heterogeneity between the studies, and a fixed effects model was chosen for the meta-analysis. Continuous data are presented as weighted mean differences (WMDs), and odds ratios (ORs) were calculated for dichotomy [both with 95% confidence intervals (CIs)]. Egger’s test was performed to evaluate the risk of publication bias. Additionally, a sensitivity analysis was performed to assess the stability of the outcome when low-quality and highly heterogeneous trials were included in the analysis. A total of 1657 articles were identified through the electronic databases and the manual review of the reference lists of the included studies. Based on the search strategy, a total of 16 studies were included in the review [17–31]. A total of 5189 patients were recruited in the final meta-analysis, and the mean patient age ranged from 36.9 to 56.2 years. Seven articles were open-label, randomized, multicentre, controlled studies; nine of the studies had a crossover design; and the other studies were prospective and observational. The common instruments used to assess these two PDEIs (sildenafil and tadalafil) were the IIEF-EF, preference, TEAEs, adherence and persistence.

These data suggest that sildenafil citrate used as a therapeutic agent may improve myometrial perfusion in FGR pregnancies by promoting myometrial small artery vasodilatation, decreasing peripheral resistance, and increasing flow within the uteroplacental bed. We originally calculated the dose of sildenafil citrate to use in this study from erectile dysfunction clinical trials data ( e.g . Pharmacokinetic data suggest that a 100-mg oral dose of sildenafil citrate produces a plasma concentration in excess of 100 nmol/liter for 4–5 h after oral dosage ( 40). We therefore decided to use 100 nmol/liter as the maximum dose in our study, as we believed that these concentrations would be attainable in the myometrial circulation in vivo . This concentration is still 100-fold less than that required for nonspecific inhibition of other PDE isoforms by sildenafil citrate (which is suggested to be in the 1–10 ?mol/liter range) ( 41). It may be that administration of sildenafil citrate may not be an medicine shoppe sildenafil appropriate therapeutic strategy in all cases where growth restriction is apparent. However, we suggest that buy sildenafil cheap in cases where an inappropriately small fetus has been identified, with no genetic abnormalities and where there are abnormal uterine Doppler waveforms present, the findings of our study justify a clinical trial investigating whether sildenafil citrate administration may lead to improved uteroplacental blood flow, improved placental perfusion, and prolongation of pregnancy.

Poor vascular blood supply to the penile arteries as a result of macrovascular disease and atherosclerotic lesions (22), reduced production of nitric oxide and cyclic guanosine monophosphate in the corpus cavernosum as a result of advanced glycosylation product accumulation (23), and impaired neurogenic and endothelium-dependent relaxation of penile arteries (24) all contribute to diabetes-associated ED. Moreover, concomitant medications frequently used in diabetic patients, such as antihypertensive agents (?-blockers, calcium channel antagonists) (25) and lipid-lowering drugs (fibrates, statins) can contribute to a reduced efficacy of sildenafil (26). Patients with type 1 diabetes are often relatively young and may thus benefit from a well-tolerated treatment regimen. The drop-out rate with sildenafil treatment is low compared with that for other treatments for ED, such as intracavernosal injections, which have a high attrition rate, pain with injection, or nodule formation (27), and penile implants, which may require implant removal because of infection (28). However, because sildenafil does not resolve ED in all patients with diabetes, each patient should be given information on other treatment options that have shown efficacy for this population. The efficacy and safety of sildenafil have been assessed from more than 11,000 patient-years of observation in controlled clinical trials, many of which focused on and/or included men with diabetes (29). The safety profile of sildenafil in this study of men with ED and type 1 diabetes is in agreement with previous reports in which the most common adverse events associated with use of sildenafil in flexible-dose studies were ...

The main surgical treatment of ED involves insertion of a penile implant (also called penile prostheses). Because penile vascular surgery is not recommended for aging males who have failed oral PDE5 inhibitors, ICI or IU therapies, implants are the next step for these patients. Although placement of a penile implant is a surgery which carries risks, they have the highest rates of success and satisfaction among ED treatment options. Penile implants are devices that are placed fully inside your body. They make a stiff penis that lets you have normal sex. This is an excellent choice to improve uninterupted intimacy and makes relations more spontaneous. Semi rigid Implant (Bendable) The simplest kind of implant is made from two easy-to-bend rods that are most often made of silicone. These silicone rods give the man's penis the firmness needed for sexual penetration. The implant can be bent downward for peeing or upward for sex. With an inflatable implant , fluid-filled cylinders are placed lengthwise in the penis. Tubing joins these cylinders to a pump placed inside the scrotum (between the testicles). When the pump is engaged, pressure in the cylinders inflate the penis and makes it stiff. Inflatable implants make a normal looking erection and are natural feeling for your partner. Your surgeon may suggest a lubricant for your partner. With the implant, men can control firmness and, sometimes, the size of the erection. Implants allows a couple to be spontaneously intimate. There is generally no change to a man's feeling or orgasm. Penile implants are most often placed under anesthesia. If a patient has a systemic, skin, or urinary tract infection, this surgery should be ... More

In March 1998, the US Food and Drug Administration (FDA) approved sildenafil citrate (Viagra ® , Pfizer Inc, New York, NY, USA) for the treatment of erectile dysfunction (ED) (FDA 1998). As of December 2005, more than 27 million men worldwide had received sildenafil for treatment of ED, including an estimated 17 million men in the US (Data on file, Pfizer Inc, New York, NY). Thus, the long-term safety and effectiveness of sildenafil can now be evaluated in men who have been taking the drug for several years. The efficacy, safety, and tolerability of sildenafil in the treatment of men with ED have been demonstrated in numerous studies of 1-year duration or less. For example, 1,358 men with ED completed 1 of 4 double-blind trials and continued with open-label sildenafil treatment in extension studies for a total treatment duration of approximately 1 year (Morales et al 1998; Steers et al 2001). In the current study, 979 of these men subsequently received up to 4 more years of open-label, flexible-dose (25, 50, and 100 mg) sildenafil. Preliminary (3-year) results were reported previously (Carson et al 2002; Padma-Nathan et al 2002), and we now present the final data. The population included patients with ED of organic and psychogenic etiology and typical concomitant medical conditions for this population (ie, hypertension, diabetes, hyperlipidemia, and a history of ischemic heart disease). Our objective was to assess the long-term safety and effectiveness of sildenafil treatment in men with ED. This was a 4-year, open-label, flexible-dose (25, 50, and 100 mg) study of sildenafil. Men who previously completed and were compliant with sildenafil or placebo treatment in 1 of 4 ... More

Although not fully investigated, restless leg syndrome (RLS) appears also to increase the rates of ED in men. It is still unclear how treatment for RLS impacts ED. Medications: Certain medications may increase ED rates in men. It is estimated that medications may be at least partially responsible for 25% of ED cases in men. Some of the most common medications that can cause ED include: antidepressants, sympathetic blockers (clonidine, methyldopa), certain diuretics (water pills), ketoconazole, H2 antagonists (cimetidine, ranitidine), anticholinergics. A variety of other medications are also associated with ED. Alcohol, cocaine, marijuana, and other drugs also can exacerbate ED symptoms. Biking/Endocrine/Low Testosterone: Excessive bicycling, endocrine disorders, and low testosterone are also risk factors for ED. Bicycling places pressure on the perineal nerves, which in excessive amounts, can cause numbness of the penis and impotence. Others: Other potential causes of ED include systemic sclerosis (scleroderma), Peyronie’s disease (excessive curvature of the penis), past trauma to the penis or pelvis, past surgeries, and prostate cancer treatment. To summarize, there are many different factors that can cause or contribute to ED. Some of the strongest contributors, such as comorbid conditions, can be modified and controlled with lifestyle changes. Most common however, ED causes are multifactorial and complex. Our urology team is here to work with you to resolve your ED and improve your sexual function. How We Diagnose ED: As described above, there are many risk factors and causes for ED.
