The clinical term for this treatment used by urologists is low-intensity shockwave therapy (LiSWT). During the treatment, a small wand-like device uses targeted sound waves to stimulate penile tissue and encourage blood flow, which can also speed up the healing process. Low-intensity shockwaves have also been shown to grow new blood vessels and improve blood flow in the penis, which is essential for erections.
Male infertility is caused by abnormal sperm production, blockage of sperm delivery or low sperm production. Treatments are available that work. .
PDE 5 inhibitors are broken down primarily by enzyme, cytochrome P450enzyme CYP3A4. Medications that decrease or increase the activity of CYP3A4 may affect levels and effectiveness of PDE 5 inhibitors. Such drugs include medications for the treatment of HIV (protease inhibitors) and the antifungal medications ketoconazole and itraconazole. Thus caution is recommended.
When possible, “nerve-sparing” methods are used in radical prostatectomy, radical cystectomy, AP resection, or TME. In nerve-sparing surgery, doctors carefully try to avoid these nerves. When the size and location of a tumor allow for nerve-sparing surgery, more men recover erections than with other techniques. But even if the surgeon is able to spare these nerves, they might still be injured during the operation and need time to heal.
The recommended starting dose is 100 mg taken as early as 15 minutes prior to sexual activity, no more than once a day. The maximum dose is 200 mg. Avanafil may be taken with or without food. As with the other PDE5 inhibitors, sexual stimulation is necessary for avanafil to work.
If you have erectile dysfunction, there are many ways your doctor can help you treat it. But you may want to consider complementary or alternative therapies, such as nutritional supplements, herbal remedies, acupuncture, and talk therapy. Just be sure to talk to your doctor first.
Erectile dysfunction (ED) or impotence means you can’t get an erection. It can also mean you aren't happy with the size or hardness of your erections, or how long your erections last.
Checking the penis for sensitivity determines any nervous system origins. Inspection of penile appearance helps rule out Peyronie's disease. A blood pressure check rules out circulation problems by checking wrist and ankle pulse.
A wide range of ED rates have been reported, even in men who haven’t had surgery. But for the most part, the younger a man is, the more likely he is to regain full erections after surgery. Men under 60, and especially those under 50, are more likely to recover their erections than older men.
Sildenafil is available as oral tablets at doses of 25 mg, 50 mg, and 100 mg. Patients should take sildenafil approximately one hour before sexual activity. In some men, the onset of action of the drug may be as early as 11-20 minutes. It's best for men to take sildenafil on an empty stomach for best results since absorption and effectiveness of sildenafil can be diminished if it is taken shortly after a meal, particularly a meal that is high in fat. Sildenafil and the other PDE5 inhibitors don't cause an immediate erection. Sexual stimulation is necessary for these medications to work.
Treatment for ED is based on the cause of the problem. Some of the treatments that may be used include:
Patients must ask themselves how important erections are – and which treatments they’re willing to consider. One option is penile injection therapy, where the man injects a medication into his penis for an immediate erection. Alternately, a device known as a penile prothesis that permanently corrects ED can be surgically implanted. Two less popular treatments are a vacuum device that pulls blood into the penis and a suppository that’s inserted into the urethra prior to intercourse.
High blood sugar levels can damage the nerves that control sexual stimulation. They can also damage blood vessels that provide blood flow to the penis to achieve and maintain an erection.
Penile erection is a complex process in which the brain, nerves, muscles and blood vessels play a major role. The main causes of erectile dysfunction include psychological and health conditions, medications, trauma and lifestyle factors.

Surgical or radiation treatments for prostate cancer, bladder cancer, or prostate enlargement (BPH) can sometimes damage nerves and blood vessels near the penis. Occasionally, the nerve damage is permanent and the patient requires treatment to achieve an erection. Sometimes, surgery causes temporary erectile dysfunction that improves on its own after 6 to 18 months.
