Some say nerve sparing & return of erections help size. Some recommend Viagra/Cialis to increase blood glow & limit atrophy.

Hello there,
I had the “RALP” done about a year ago. At my state of erection, I’ve lost almost 2 inches in Penis length and an undetermined but noticeable amount in my girth!
Like things weren’t challenging enough for men dealing with Prostate Cancer that they have to deal with their so called “Manhood” as well! It’s really like adding insult to injury. You have to endure all of the many associated issues that come with treating and recovering from Prostate Cancer plus loose some length and girth in your Penis. The so called “good news” is that on average, most men regain most if not all of their loss of length within a year following a Radical Prostatectomy. At least with with this man……that has not been the case.
However, you can start using a VED, Vacuum Erection Device to help with your overall Penile Rehabilitation program. You need to facilitate circulating fresh blood in and out of your penis to replenish the penile tissues. With the loss of “Nocturnal Erections!” You know, the ones you used to get at night or very early in the morning? Those aren’t happening any longer so you need to replace the benefits of those with a Penile Vacuum Device.
I started using one several plus months ago and it really does facilitate gaining erections and replenishing my penile tissue with fresh blood to assist in my overall penile recovery.
If required, you can also use the devise to obtain erections for penetrative sexual intercourse.
I highly recommend it. I can definitely feel some of the length and girth in addition to a more general “fullness” back in my penis.
Best wishes and good luck.
On a side note, if you want to have more predictable and effective erections for sexual intercourse, try the penile injections of TRIMIX. It’s an injectable medication that consists of 3 different Vasodilators. It’s really effective and for patients like myself where the pills like VIAGRA and CIALIS were totally ineffective, the TRIMIX has been the perfect answer. The needle is very similar to a diabetic’s needle used to inject insulin.
There’s a slight sting but frankly, the entire process is pretty painless and more than worth the very effective results.
Good luck,
GODSPEED
