What are Bio-Identical Testosterone Pellets?

Used in the treatment of low testosterone, pellets provide a consistent, sustained delivery of testosterone when implanted under the skin. Subcutaneous testosterone implants have a proven record of safety and have been in use in Europe and Australia since 1938, and in America since 1949.

What are the pellets made from?

They are 100% pure testosterone fused into a sustained release form. The pellets are derived from extracts of wild yams, and are bio identical, meaning they are the exact replication of what the body makes.

What are the advantages of pellet implant over gels and creams applied to the skin, or over testosterone injections?

The typical male body requires about 3 mg of testosterone a day to function at his peak. Over 5-months, 600 mg (six pellets) will dissolve at a rate of about 3-4 mg a day.

Contrast this to creams and gels, which require applications of 50-75 mg a day to provide a similar testosterone effect. Injections require 100-200 mg every 2 weeks to get an equivalent effect. And with creams, gels and injections, all that excess testosterone can be converted by the body to estrogen through the process of aromatization, directly interfering with the metabolic benefits of testosterone. Even worse creams, gels and injections deliver the hormone in peaks that can suppress the body’s own production of testosterone.

How are they administered?

A small incision is made over the posterior hip. Your doctor implants the pellets in the subcutaneous fat of hip. No stitch is required. The procedure takes about 5 minutes.

Is this therapy FDA approved?

The ingredients in the pellets are all FDA approved. The distribution of the pellets is FDA regulated. The procedure is a standard minor surgical procedure.

How long will the treatments last?

The average duration is 5 months, with the range of 4–to-6 months depending on the person. Everyone is different so duration depends on how you feel and what the doctor determines is right for you. If you are really active, you’re under a lot of stress; your pellets may dissolve at a faster rate. Dissolution rate is based on cardiac output.

Are there any side effects?

There are no serious side effects. Infection and/or expulsion of the pellets is rare. The vast majority of men are pleased with the results. While the majority of studies have concluded that testosterone therapy lowers diabetes risk, prevents bone loss, improves mood, lowers cardiovascular mortality, and lowers all-cause mortality in men with low testosterone, a recent study did show an overall increased mortality in men with advanced cardiovascular disease who were put on testosterone replacement.  Men with pre-existing cardiovascular disease should receive testosterone cautiously.

How long has Dr. Peterson been treating his patients with testosterone pellet implants?

Since 2004

What is meant by “autologous” stem cell prolotherapy”?

Using your own adult stem cells for repair and regeneration is called ” autologous” stem cell prolotherapy, and has many advantages over standard joint replacement surgery. Adult stem cells are pluripotent, meaning that they have the potential to differentiate into whatever types of tissues are needed in joint repair. They have the ability to become cartilage, tendon, ligament, bone, and muscle. When used in combination with platelet rich plasma, the effect on degenerated joints can be remarkable.

What tissue do we harvest to make your stem cells?

The procedure we use harvests a tissue complex known as AD-SVF, or Adipose Derived-Stromal Vascular Fraction. AD-SVF provides a rich tissue matrix and bio scaffolding to aid in repair and regeneration of affected tissues. These specific tissue fractions are located within the highly vascular adipose bed and serve to nurture and protect your stem cell population. When harvested along with the stem cells, and mixed with your own platelet rich plasma, these tissue products provide the tissue rich matrix, the cytokine cell signals, and scaffolding necessary for stem cells to differentiate and grow into the desired host tissue. Therefore your adipose tissue is the most ideal site for harvesting stem cells.

In summary, adipose-derived regenerative cells:

  • Can be collected in far greater concentrations than those from bone marrow
  • Are able to differentiate into multiple lineages including cartilage, bone, ligament, tendon, blood vessels and nerves.
  • Fractions isolated from adipose tissue contain a diverse mixture of regenerative cells, including:
  • Mesenchymal stem cells (MSCs)
  • Endothelial progenitor cells
  • Pericytes
  • Immune cells
  • Fibroblasts
  • Other growth factor-secreting bioactive cells

What are the advantages of these regenerative cells?

Regenerative cells “communicate” with the cells of their local environment through paracrine and autocrine modalities, creating the optimal environment for repair.

Regenerative cells produce a variety of both secreted and cell surface substances that regulate tissue growth, integrity, and function.

What’s the difference between the adult stem cells that we use at Oregon Regenerative Medicine and banned fetal stem cells?

The adult stem cells that we use autologous, meaning that we harvest stem cells from each patient’s own body. Fetal stem cell lines are derived from fetuses, and are not derived from the patient in whom they will be used and must be cultured to replicate and increase their cell numbers before being injected into the host.

How do we harvest your adult stem cells?

The most desirable stem cells for joint repair and regeneration are called mesenchymal stem cells. Mesenchymal stem cells have the ability to differentiate into cartilage, ligaments, tendons, and other connective tissue. Adipose tissue is an ideal site for harvesting mesenchymal stem cells, and compared with bone marrow aspirate, adipose tissue possesses between 500 to 1000 times the number of mesenchymal stem cells and stem-like stromal-vascular cells. The tissue we harvest is known as adipose derived stromal vascular fraction, or AD-SVF. This tissue is usually harvested from the buttocks or thighs and can be harvested from other fat deposition sites in the body. Once the optimal site is selected, an anesthetic is injected so that the Tulip harvester can be used to painlessly extract AD-SVF. This AD-SVF is minimally processed to remove impurities, concentrated, and combined with your own platelet rich plasma. This complex cell-tissue matrix is then injected into your damaged joints, ligaments and tendons.

Is the harvesting procedure painful?

The stem cell harvesting procedure is minimally invasive and only requires 2-to-4 small ¼” incisions. A local anesthetic will be used to numb the area before the procedure. While many patients find the procedure only mildly uncomfortable, most of our patients choose to have nitrous oxide conscious sedation. Nitrous is a safe and effective method of sedation and will be administered through a breathing mask. Nitrous allows you to remain conscious throughout the entire procedure. Nitrous diminishes pain, reduces anxiety, and shortens your perception of time during the procedure. Nitrous will not leave you feeling drugged or drowsy.

Why does Dr. Peterson use ultrasound (MSKUS) for diagnosis and injection guidance?

In addition to substantially lower costs, MSKUS has several advantages over MRI and fluoroscopy in orthopedics. First, Dr. Peterson is able to observe real-time continuous imaging of the affected injury, and is able to correlate hands-on palpation with direct ultrasound images. Unlike a static snapshot from an MRI, ultrasound offers the ability to scan the tissue during movement, thereby enabling a functional evaluation of the joint and exact needle placement for graft products. Fluoroscopy is ideally suited for guiding stem cells directly into intervertebral disks.

Frequency of treatment

The number of treatments required will depend on the condition being treated, the severity of injury, and how long the injuries and present. Most people will initially require 3-5 sets of PRP injections spaced 2 to 6 weeks apart. Stem Cell treatments are spaced from 4-8 months apart and 2-treatments age generally required. Often Dr. Peterson can predict the number of treatments needed at your 1st evaluation.

How soon can I go back to regular activity?

PRP, Prolotherapy and Stem Cell therapies stimulate your own body to do the repairing, and this requires time. Your body will need to go through all the necessary physiologic steps for repair, and your activities will need to keep pace with this rate of repair. Initially, gentle exercise and movement will be prescribed. Most people are able to resume activities of daily living within the 1st few days, followed by moderate exercise within the 1st 2 weeks. Avoiding the activity that caused the injury will be recommended until healing is complete.

How will I feel after my treatment?

Be prepared to take it easy for 2-to-4 days after treatment. The harvest sites will be mildly tender and there may be mild swelling. Joints and other regions treated will also be tender and quite stiff. If you are having your knees or hips injected, you may need to use crutches for a few days. You will benefit from strong pain medication for the 1st 24- hours and a prescription of Vicodin or other pain medication will be offered. For most pain, we recommend that you apply moist heat, 20 min. on, 20 min. off. Repeat as needed. For harvest site pain, wait 24 hours after the procedure before applying heat.

Adjunctive treatment

It is logical and self-evident that your overall health contributes to your rate of repair and recovery. Your physical conditioning, hormone status, and nutrition are all important factors contributing to the success of your procedures. Our team can assess you for your nutritional and hormonal status, and assist you in maximizing your road to recovery.

Will I need to exercise after my treatment?

Your ability to respond to stem cell therapy is enhanced by exercise. People with low activity levels tend to have impaired stem cell generation. For this reason you will need to engage in gradually increasing duration and intensity of exercise after your treatment. We consider exercise bikes and recumbent bikes to be ideal in strengthening both hips and knees. For strength training, we recommend you read The Slow Burn Fitness Revolution by Michael Eades, MD.

Does my diet affect the quality of my treatment?

Your diet determines the quality of your AD-SVF and the ease of extraction. We recommend an anti-inflammatory diet rich in fresh and cooked vegetables, high quality Omega 3 rich proteins including salmon, sardines, cold water fish, tree nuts, hemp seeds, flax seeds, chia seeds. Fresh berry fruits will improve the quality of your SPF graft and stem cells.

Think of it this way: would you prefer to inject a sample of inflammation causing McDonald’s French fries grease into your joints, or healthy, omega-3 rich inflammation-reducing fats?

Eat a healthy, low-fat meat light meal the night before your appointment. If your appointment is in the morning, then have a small smoothie or green drink after rising. Avoid eating fats for 2 days prior to your appointment.

Does hormone deficiency contribute to my arthritis?

Hormone deficiency can impair your body’s ability to repair and to generate healthy cartilage and stem cell populations. If you are over 40 years of age, or have symptoms of hormone deficiency, hormone testing and treatment with bio-identical hormones may improve your response. Talk to your doctor about your hormone status and they will recommend a course of action that fits your profile.

What are connective tissue injuries, and how are they related to my pain?

Tendons and ligaments are composed of   remarkably strong, elastic collagen fibers. While most people recognize the importance of tendons in musculoskeletal injury, The importance of ligaments in musculoskeletal injury is often overlooked. Not only do ligaments stabilize our bone to bone connections, they are densely embedded  nerve sensors that provide us with  pain and proprioception input, allowing smooth and fluid movement. Injury to ligaments  not only causes pain,  but also results in destabilization of the joints. When overstretched, Ligaments lose their elasticity become lax. Lax ligaments attempt to correct this destabilization by recruiting muscle contraction, which leads to the muscle spasms and pain associated with back and other types of injuries. Ligament injury and the resultant muscle spasms cause referred pain patterns that are often mistaken for primary nerve injury, herniated discs, and/or nerve impingement, leading to unnecessary surgeries.

Do I need surgery if my MRI shows I have a herniated disc? Or a torn meniscus?  Or a torn rotator cuff?

While MRI technologies provide great insight into the  anatomy of dysfunction, they can be misleading, often missing the cause of our patient’s pain. Well over 30% of patients with no history of back pain or injury will show disk herniation on an MRI. Dr. Bradley K Weiner, reported in the Journal of Orthopaedic Surgery and Research (2008) that 28% of patients with pain who showed disk herniation on an MRI did not show herniation at surgery. What this means is that while disk herniation can be the cause of back pain, it is often no more than a normal sign of back degeneration, and that back pain is caused by many different types of injuries.

What about MRI of the knee?

In a study of 20 symptom-free atheletes, Brunner showed  that 50% had abnormal findings on MRI, including tears to the meniscus, ACL, PCL, and MCL. Kornick looked at 74 symptom free volunteers age ten to seventy-four, and 25% showed a torn meniscus on MRI. Martin England MD published in September, 2008 in the New England Journal of Medicine that meniscus tears on an MRI should be regarded as an incidental finding, and found in 991 symptom-free subjects aged 50-90 years, that 60% of these symptom-free people had MRI positive meniscus tears, concluding that “Incidental meniscal findings on MRI of the knee are common in the general population and increase with increasing age.”•NEJM Volume 359:1108-1115, September 11, 2008, Number 11
