Hi!

I'm Dr. Anne Truong, MD

Dr. Anne Truong is a highly respected physician, best-selling author and internationally sought-after speaker on the topics of regenerative cell medicine, pain management, and applications for aesthetics and sexuality.

If you have high cholesterol, an enlarged prostate, and erectile dysfunction, you’ve probably been handed three diagnoses, three prescriptions, and three separate explanations. Here’s what most men never hear, these aren’t three conditions. They’re one underlying breakdown wearing three different masks.

This case study follows Joe, a 70-year-old man who was told his bedroom days were behind him. By connecting his anemia, his cholesterol, and his prostate, his care team uncovered the single mechanism weakening his blood flow and his erections, then built a plan to repair it from the inside out.

Meet Joe: Healthy on Paper, Struggling in the Bedroom

Joe is 70, stands 5’9″, weighs about 165 pounds, and works out four days a week. He eats reasonably well, though his blood sugar sits in the borderline diabetic range. For six years, he’s been able to get an erection but struggles to keep it.

He’s married to a wife 15 years younger, and he wants his sex life back. He doesn’t want to rely on ED pills, he’s never tried a pump, and above all, he wants to know why this is happening.

What the Questionnaires and Blood Work Revealed

Before any treatment, Joe completed validated questionnaires and a full blood panel. Together, they told a much bigger story than “it’s just age.”

Severe ED and Moderate Prostate Symptoms

Joe scored 7 out of 25 on the ED questionnaire, which places him in the severe range. His prostate questionnaire showed moderate symptoms: a weak urine stream and three trips to the bathroom every night, which wrecked his sleep. His PSA was 3.4, not alarming on its own.

Hidden Clues in His Lab Results

His blood work turned up several quiet contributors:

  • High cholesterol, already being treated with Repatha
  • A hemoglobin A1C of 5.9, borderline but not medicated
  • Anemia, meaning a low red blood cell count from low iron
  • Borderline low vitamin D, a known contributor to ED

High Total Testosterone, Low Free Testosterone

Joe was already on testosterone cypionate injections, and his total testosterone was high. But his free testosterone, the active form your body actually uses, was low. The culprit was high sex hormone binding globulin (SHBG), which binds testosterone and keeps it locked up, and his testosterone questionnaire confirmed he was still deficient.


The Real Root Cause: Endothelial Dysfunction

Every finding pointed back to the same place: the endothelium, the thin lining inside your blood vessels. When it’s damaged, it produces less nitric oxide, and less nitric oxide means less blood flow, not just to the penis but everywhere in the body.

“You have one underlying breakdown masquerading as three separate diagnoses.”

How Anemia, Low Vitamin D, and Cholesterol Add Up

Anemia means fewer red blood cells carrying oxygen, so the tissues that need it most get shortchanged. Low vitamin D contributes to ED on its own. High cholesterol damages the endothelium directly, cutting nitric oxide and choking off blood flow.


How an Enlarged Prostate Quietly Fuels Erectile Dysfunction

This is the connection most men never hear about. An enlarged prostate doesn’t just affect urination; it works against your erections from several directions at once.

Shared Blood Vessel Damage

An enlarged prostate shares the same endothelial dysfunction behind ED. Lower nitric oxide reduces blood flow throughout the pelvis, and that includes the penis.

A Body Stuck in Fight or Flight

An enlarged prostate raises sympathetic tone, your body’s stress response. That tightens the smooth muscle of the bladder neck and the corpus cavernosum (the erectile tissue of the penis) at the same time. Since an erection requires that tissue to relax, constant tension works directly against you.

Lost Sleep, Stress, and Medication Side Effects

Getting up two or three times a night destroys sleep and leaves you exhausted the next day. It can even lead to social withdrawal and a feeling of losing control of your own body, all of which feeds stress, and stress feeds ED. On top of that, common prostate medications like finasteride, dutasteride, and alpha blockers can contribute to ED themselves.


The Inside Out Treatment Plan

The goal wasn’t to patch one symptom; it was to restore the whole system, and healing is possible even at 70. Joe’s plan was built around the Get Hard System, which focuses on restoring six body systems so the body can heal from ED.

Optimize Free Testosterone

The first step was a modest increase in his testosterone dose. Repeat blood work then confirms whether his free testosterone is climbing.

Treat the Prostate First

Joe receives in-office prostate therapy using a device that delivers far infrared energy, vibration, and heat. Increasing blood flow to the prostate helps it heal and shrink. Fewer nighttime bathroom trips mean better sleep, and every other part of the plan depends on it.

Strengthen and Oxygenate the Pelvis

Weak pelvic muscles were also part of the picture, so Joe uses a neurostimulating Kegel device at home. A penis pump stretches the corpus cavernosum and draws in oxygen-rich blood to support healing. At-home pulsed electromagnetic therapy (PEMF) covers the whole pelvic region to boost circulation.

Repair the Endothelium Through Diet

The Mediterranean diet is the foundation for healing the blood vessel lining from within. Expect it to take roughly six weeks to 90 days to see results. Joe was already exercising, which helps, but exercise can’t fully do its job when sleep is broken.

Calm the Nervous System With Box Breathing

High sympathetic activity tightens the pelvic muscles and the penis, making erections harder to achieve. Ten minutes of box breathing a day helps lower that tone, and the calming effect carries through the rest of the day.

Regenerative In-Office Treatments

To address the penis and pelvic floor directly, Joe’s in-office treatments include:

  • Regenerative injections using platelets from his own blood to bring more blood flow to the penis
  • Botox injections to help the erectile tissue relax
  • Focused shockwave therapy on the shaft, the base, and the pelvic floor to break down fibrous tissue and restore flexibility

Why This Goes Far Beyond the Bedroom

Every part of this plan serves four purposes: repair the endothelium, increase blood flow, lower sympathetic tone, and strengthen the pelvic muscles. ED is treated as a whole functional unit, not just a problem with the penis.

That approach does more than restore erections. Better blood flow lowers Joe’s risk of a heart attack three to five years down the road, and if he sticks with the diet, exercise, restored sleep, and box breathing, he’s likely to live longer too.


Final Thoughts

Joe wasn’t dealing with three unrelated problems. He was dealing with one breakdown in his blood vessels, amplified by his prostate, his labs, and his stress. Once those connections were clear, the path forward was clear too.

“Just remember, it’s never too late. You are not broken.”

Whether you’re 50 or 70, the right bloodwork can reveal what’s really driving your ED.

Frequently Asked Questions (FAQs)

  1. Can my enlarged prostate really be causing my erectile dysfunction?
    Yes, an enlarged prostate can weaken erections by reducing pelvic blood flow, tightening erectile tissue, disrupting your sleep, and through the side effects of some prostate medications.

  2. Why is my free testosterone low when my total testosterone is high?
    High sex hormone binding globulin (SHBG) can bind up your testosterone, leaving less of the active, free form available for your body to use.

  3. Can being anemic affect my erections?
    Yes, anemia lowers the oxygen delivered to your tissues, including the erectile tissue that depends on healthy blood flow.

  4. How long will the Mediterranean diet take to help my blood vessels?
    Repairing the endothelium through the Mediterranean diet typically takes about six weeks to 90 days of consistent eating.

  5. Am I too old to improve my erectile dysfunction at 70?
    No, this case shows that a whole-body approach to restoring blood flow and pelvic function can still help men heal ED at 70.
