Sildenafil (Viagra), tadalafil (Cialis), and vardenafil (Levitra) are all phosphodiesterase type 5 (PDE5) inhibitors. These medications work by relaxing the blood vessels in the penis, allowing blood to flow in and create an erection. They are taken orally, usually 30 minutes to 1 hour before sexual activity. These medications are effective in most men, but may not work for everyone.

Platelet-rich plasma (PRP) therapy is a relatively new treatment option that is being studied for the improvement of erectile dysfunction (ED). PRP therapy involves taking a small amount of the patient's own blood, spinning it in a centrifuge to separate the platelets from the other blood cells, and then re-injecting the concentrated platelets back into the patient's body.

The theory behind using PRP for ED is that the platelets contain growth factors that can help to promote the growth and repair of blood vessels, which can improve blood flow to the penis and help to achieve and maintain an erection. Additionally, it may also improve the functioning of nerve and tissue in the penis, leading to improved sexual function and erectile quality.

This therapy involves injecting a medication directly into the side of the penis. The medication causes blood vessels in the penis to dilate, increasing blood flow and creating an erection. These injections are typically given by a healthcare professional and can be self-administered after proper training.

This therapy involves using a device that creates a vacuum around the penis, which causes blood to flow into the penis and create an erection. Once the erection is achieved, a constriction ring is placed around the base of the penis to maintain the erection.

This therapy involves surgically inserting a device into the penis to create an erection. There are two types of penile implants: inflatable and malleable. Inflatable implants involve a pump and a reservoir that is filled with fluid to create an erection. Malleable implants involve two rods that are surgically implanted into the penis and can be bent up or down to create an erection.

This therapy may be used if the cause of the erectile dysfunction is a hormonal imbalance. Hormone therapy can help to correct this imbalance and improve erectile function.

This therapy may be used if the cause of the erectile dysfunction is psychological in nature. Psychological therapy can help to address any underlying psychological issues that may be contributing to the erectile dysfunction, such as anxiety or depression. This can include individual or couples therapy, or cognitive-behavioral therapy.
