Blinded By ED Drugs?

For years, Big Pharma has denied the link between their erectile dysfunction drugs and blindness. They blamed any vision loss a patient developed on “pre-existing conditions.”

But a new study provides definitive proof of a connection between using these drugs and serious eye damage.1 Let me explain…

For 14 years, researchers from the University of British Columbia in Canada tracked more than 200,000 men with an average age of 64.

Their research, published in the journal JAMA Ophthalmology, concluded that men who regularly used ED drugs were 85% more likely to have suffered from three vision-robbing conditions:

    • Serious retinal detachment – The sudden appearance of floaters or spots, blurred vision, flashes of light, and reduced peripheral vision. Men who use erectile dysfunction medications were 158% more likely to have this condition.
    • Retinal vascular occlusion – Sudden blindness in one eye, complete blurring of eyesight, and steady vision loss over weeks. ED drug users had a 44% higher risk of developing this disorder.
    • Ischemic optic neuropathy – Symptoms include fever, fatigue, and pain in the neck and temples, followed by vision loss. The risk of this condition for men using ED medication increased by 102%.

None of the men in the study had any vision problems prior to using the pills.

ED drugs work by blocking an enzyme that breaks down nitric oxide. As a regular reader, you know that NO expands your blood vessels. This increases blood flow to the genitals, allowing them to become filled with blood.

The outcome is an erection within the hour.

But more blood to your genitals means less blood flow to your eyes. And that can lead to serious vision problems. But that’s not all. These synthetic pills can cause headaches and body aches, indigestion, dizziness, and diarrhea.

Hardly the romantic outcome you want!

At my clinic, I help patients increase bedroom blood flow naturally using a variety of supplements, nitric oxide boosters, and the latest technological advances – including a painless and simple procedure known as the P-shot.

P-Shot is short for “Priapus Shot.” It’s named after the Greek god of fertility. And it’s a form of platelet-rich plasma, or PRP for short.

PRP is a simple treatment. It starts with a small amount of blood drawn from your arm. The blood is run through a centrifuge to separate out plasma with a high concentration of platelets.

When PRP is injected into an injured area, it promotes healing and regenerates injured tissue. It also activates the growth of new blood vessels to increase blood flow.

And since low blood flow is a major cause of ED, PRP helps with getting more powerful erections. It can also boost sensitivity and pleasure, sexual stamina, and penis health.

In a recent meta-analysis, researchers followed more than 3,800 men with erectile dysfunction. They concluded that platelets and the powerful proteins they contain called growth factors are the best way to treat ED in older men.2

Another new clinical study revealed that 69% of men saw improvement compared to the placebo group. For most the men, the benefits lasted six months or longer.3

A P-Shot takes just 15 minutes. PRP from your own blood is injected directly into the penis. But don’t worry — a strong numbing cream makes the shot virtually painless. And there’s no downtime. You can resume sexual activity within hours.

If you’re interested in scheduling an appointment for the P-Shot, or any other type of PRP, just call my staff at the Sears Institute for Anti-Aging Medicine at 561-784-7852 for details. Or you can visit my website at

Two More Ways To Naturally Enhance Erectile Performance

Here are a couple more proven sex boosters I tell my patients about.

    1. Boost blood flow with these two powerful amino acids. I advise my patients to adopt a diet rich in these biochemical cousins. They’re amino acids that team up to make nitric oxide, which boosts blood flow to give your sex life a real lift. Great food sources of these great sex nutrients include peanuts, almonds, sunflower seeds, walnuts, tuna, chicken, salmon, shrimp, eggs, and watermelon. If you want to supplement, I recommend 1,000 mg of L-citrulline and 6,000 mg of L-arginine a day.
    2. Try this ancient aphrodisiac. The Romans are known to have drunk beet juice two hours before having sex. It has also been shown to heighten bedroom performance by raising nitric oxide levels. The beet’s ability to improve circulation has been documented in numerous studies.4 Drink it straight or mix 1 gram of beetroot powder into your favorite smoothie. You can also supplement with beet capsules. I recommend 1,000 mg a day. But for the best results, I suggest crunching on a piece of beetroot. As you chew, it combines with saliva and bacteria on your tongue and turns into nitric oxide.
