Most commonly, ED is vasculogenic (caused by impaired blood flow into the corpora cavernosa of the penis). This happens with age, high cholesterol, high blood pressure, diabetes, or other causes of vascular disease, as well as certain medications. Patients with vasculogenic ED should be evaluated for possible vascular issues, including heart disease. This can be done by a primary care physician.
ED can also be neurogenic, meaning caused by damage to the nerves that initiate blood flow to the penis. This can happen with diabetes or back injuries. Additionally, neurogenic ED is common in men who have been treated for prostate cancer. All prostate cancer treatments can potentially cause neurogenic ED.
The third type of ED is psychogenic. This happens when arousal is impaired due to psychological factors. This is commonly due to performance anxiety & is the most common cause of ED in young patients. That being said, psychological factors can contribute to ED in any man. Basically, if you are thinking about whether or not your erection is going to work rather than focusing on your partner, you are out of the game.
Although low testosterone is not generally a direct cause of ED, it can cause decreased interest in sex, which can secondarily impair erections.
A critical amount testosterone is generally required for good erections.

The X-shot is a regenerative medicine approach that may potentially turn back the clock on ED by stimulating re-growth of lost blood vessels and nerves. The X-shot is a concentrated solution of stem cell-derived exosomes, containing a rich assortment of growth factors, proteins, and lipids.
The P-shot is a concentrated solution of the patient's own platelets, rich in growth factors.
PT-141 is used primarily to increase sex drive and sexual satisfaction, as well as to improve erections. PT-141 is FDA-approved for hypoactive sexual desire in women (referred to as The Female Viagra), and currently being studied in men. Speaking scientifically, PT-141 is a 7 amino acid peptide that acts as a melanocortin receptor agonist which leads to release of dopamine, increasing sexual desire. About 1/3 of men who do not respond to medications such as Viagra were able to obtain adequate erections following administration of PT-141 in one study.
