There is a wealth of information on the web dealing with Prostate cancer and erectile dysfunction. One of the best trove of information has been compiled by Charles Maack, a prostate cancer survivor. Below is a link to his PDF
Important in the foregoing information is for you to recognize that the more you put into return of erectile function (as well as continence), the more likely it will occur earlier than later.
Men with deficiency in Vitamin D levels can experience Erectile Dysfunction issues. From:
“Our study shows that a significant proportion of ED patients have a vitamin D deficiency and that this condition is more frequent in patients with the arteriogenic etiology. Low levels of vitamin D might increase the ED risk by promoting endothelial dysfunction. Men with ED should be analyzed for vitamin D levels and particularly to A-ED (arteriogenic ED), and for patients with a low level, Vitamin D supplementation is suggested,”
Men experiencing ED should include having their 25-hydroxy Vitamin D level checked. A level of at least 50ng/ml should be attained, and for men having been treated for prostate cancer, a preferred level should be within the range of 60ng/ml to 75ng/ml. If deficient, total daily intake of Vitamin D3 as supplement should likely be between 6000 IU to 7000 IU, and once the desired level is attained, likely 5000 IU total daily will maintain that level, though men should continue to periodically have their 25-hydroxy Vitamin D level checked to make sure.
This next paper supports the information in the foregoing paper by commenting “PDE 5 inhibitors will not be helpful for men who experience impotence due to a prostate cancer treatment that has damaged the neurovascular bundles that are attached to the NANC. Without the presence of nitrous oxide, the chemical cycle never begins.” And again, this would include the absence of neurovascular bundles. (NANC neuron: nonadrenergic, noncholinergic neuron).
Importantly, penile injections can still provide reasonable erections for intercourse or, alternatively, penile implants as well.
A consideration for men experiencing erectile dysfunction from either surgical removal of, or radiation to, the prostate gland:
There are prostate cancer survivors who have learned that in addition to, for example the PDE5 inhibitor Viagra – or even in lieu of a PDE5 inhibitor – a combination of L-Arginine, Acetyl L Carnitine and Propionyl L Carnitine at 2000mg daily each, may be effective for return to hopeful reasonable erectile function as well as occur more rapidly.
