Question: i suffer from ed. i had been taking viagra regularly and had--until March--no difficulty in getting results. Suddenly viagra ceased to work. My PCP prescribed cialis, and it worked for two weeks. He then gave me a prescription for levitra. Same thing. After that, he referred my to a urologist. The urologist whom I saw Thursday put me back on cialis, and said my problem was not waiting long enough. An hour minimum. Well and good. I tried that today. Nothing. In the meantime, I--on my own--had decided to increase intervals between masturbation. I have done nothing since Friday. I have had no ejaculations now for two weeks now. The urologist told me to return to him in a month. I can't believe he expected me to go that long. My thought is to next try levitra, wait a week, and if nothing happens, contact the urologist. What do you think? (The urologist is aware of all the medications I take, ambien, ativan (occasionally) and said they posed no problem. I even cut down on them). This thing is really getting to me

Thanks for that reply; it was quite helpful
I am not a diabetic and my blood pressure is normal. Do you think the idea of increasing intervals between masturbation is a bad idea? The longer the interval, the more likely a salutary result. At least that sounds plausible to me As for the idea of waiting a month for a follow-up, I think, given what's happened, that is too long.
I should add that the urologist found my cholesterol to be "a little high" and prescribed Lipitor. They say depression can cause ed but in my case anyway, it's more likely the reverse. What do you think of pumps and--the word shivers down my spine--injections.

I realize that. On the other hand (no pun), doing so every day has psychological consequences--tingling sensation in the penis, among other things--that can be very frustrating. I will ask the urologist to perform the tests you suggested. I should not attempt to masturbate out of a sense of duty. Do you agree?

Quick question--does the test take place in the doctor's office?

My next appointment is not for a month, but I think--given the abject failure of the strategy he recommended (wait an a hour and you should be OK), I should contact him earlier. That my decision of course and I realize that, but I wonder if you would
be kind enough to comment.

Thanks again. This dialogure has been most helpful.

I have an appointment with the urologist on Monday 16 May. I will discuss the Doppler Ultra Sound Scan, but this may not be possible immediately. I leave for Berlin on 25 May and won't be back till the end of XXXXXXX

Have you heard of Coverlet Release-impulse? A needle. Is that dangerous,

I may add that I tried again today with Levitra. Nothing. This came on so suddenly.

Caverject Impulse is the brand name of a medicine that is frequently prescribed in Canada for treating erectile dysfunction in men. Erectile dysfunction is fairly common and though there are no accurate statistics on the number of males suffering from this condition, doctors are certain that almost fifty percent of men aged between forty years and seventy years suffer from some form of this disorder. In order to combat this condition and instil confidence in men, doctors often prescribe Caverject Impulse as a viable treatment option. The chief ingredient in Caverject Impulse is alprostadil, available as the naturally occurring variation of prostaglandin. The medication is distributed by Pharmacia & Upjohn, a division of Pfizer Inc and is available in two strengths of 10mcg and 20mcg. Since the medicine is to be injected on to the patient’s penis, it is presented as a comprehensive package comprising a single-dose, dual chamber, disposable syringe structure. The front chamber contains a glass cartridge containing sterile and freeze-dried alprostadil and while the rear chamber contains sterile water. The actual solution to be injected is reconstituted using the sterile water and the dry medicine provided. After reconstitution, the volume of the medicine becomes 0.64ml of which 0.5ml is delivered inside the penis. Depending on the strength of Caverject Impulse used, the injected solution provides either 10mcg or 20mcg of alprostadil in your penile area. Once injected, the medicine produces an erection in about five to twenty minutes and the erection lasts for about thirty minutes to an hour.

Just wanted to let you know that I had a major ejaculation today, the first time in three weeks with the help of Viagra, the medication that worked so well for so long.

Does this change your (electronic) diagnosis?

Then go ahead with the PDS? (see above).
