S.T.I.M. Therapy for the Penis (STIM™ Therapy)

Superconcentrated Thrombocyte Injections for Men

Platelet Rich Plasma (PRP)

Platelet Rich Plasma (PRP)

STIM™ therapy  was coined by Beverly Hills plastic surgeon, Dr. Tim Neavin, to describe the use platelet rich plasma and negative pressure for male enhancement. It consists of two components:

  1. STIM™ shots or injections of PRP into the penis
  2. Negative pressure therapy with “penis pump” to expand the penis

Although every man’s experience from STIM therapy varies, the purpose of STIM therapy is to enhance sensation in the penis, improve ability to achieve erection, and potentially add volume to the penis in both length and circumference by promoting the growth of new tissue.

Platelet rich plasma, or PRP, is the platelet (thrombocyte) component  of blood that has been concentrated.  Because it is from your own body, it poses no risk for allergic reaction. PRP is a natural and safe solution.

Platelets are   chemical signals which stimulate cell repair, proliferation and differentiation for tissue regeneration.  PRP therapy has been used in various fields of medicine relying on its healing capacity to facilitate the repair of various tissues. Orthopaedic, cardiovascular, ENT, wound healing, and plastic surgeons have been utilizing the potent growth factors in PRP for years.  It has recently gained momentum because technology has readily afforded physicians the capacity to prepare PRP quite easily and efficiently in the office.

The procedure starts with the application of topical anesthesia to the area just above where the penis meets the pubic area and along the shaft of the penis.

Injections of lidocaine are then introduced to the pubic area to create a field block to reduce sensitivity to the penis.

After the delivery of local anesthesia, 6 injection points are marked.

The tube is then spun at an appropriate speed and duration to concentrate the platelets without inciting injury.  If the tube is spun too fast or too long, the platelets, which are fragile, can fracture causing a premature release of factors.

The concentrated platelets, PRP, is then transferred into a syringe for injections into the marked areas of the penis.

Immediately after injection, negative pressure is applied.

Immediately after injection, negative pressure is applied.

Generally within 10 to 15 minutes the penis pump will achieve erection of the penis.

Generally within 10 to 15 minutes the penis pump will achieve erection of the penis.

With the aid of negative pressure, the growth factors and cytokines released from the platelets can disperse into the corpus cavernosum more evenly.

Possible benefits from STIM therapy include:

  • Improved sensation of the penis
  • Improved ability to achieve erection of the penis
  • Possible straightening of the penis (improved appearance)
  • Enlargement of the penis

Many men report improvements within days after the procedure.  To amplify the response, STIM therapy can be performed every 60 to 90 days or until desired results are achieved.

“STIM therapy is a remarkable procedure.  Two weeks after injection, I measured myself and gained half an inch in length, roughly the same in girth.  In addition, both ease in achieving erection and sensation have increased dramatically.  A few days ago which was about 3 weeks after injections, I was able to have sex with my girlfriend 4 times in the same day.  I don’t recall ever being able to do that. I would highly recommend this procedure to anyone experiencing difficulties with sex or just wish to improve their sex life. ” A.S. 28 year old man

Penis Enlargement with Fat Transfer

STIF therapy adds autologous fat to the injection. Fat is collected from the love handles or abdomen and then processed through filters to allow injection through very fine needles. This thin fat is often called nano-fat. Nano-fat contains fat cells, stromal cells, and stem cells. The purpose of fat transfer is not only to add volume to the penis, but to improve sensation as well.

Once fat is collected, it is filtered to reduce viscosity (called micronized fat or nano-fat) and injected with a cannula into the penis above the Buck’s fascia in the subcutaneous plane. Up to 40 cc or more of fat can be injected with or without the addition of PRP.

The procedure, like PRP, can be performed under local anesthesia with the aid of a regional nerve block to the penis. In the locations where fat will be collected, generally the flanks, love handles, or abdomen, tumescent fluid is injected to anesthetize the region. Fat harvest can be combined with traditional liposuction. Liposuction of the mons may also impart the illusion of a fuller penis by unmasking it from hidden tissue.

Fat transfer to the penis, like any fat transfer procedure can yield unpredictable take. While it is certain that 100 percent of the cells will not survive the transfer, over correction is performed to counter this fact. The penis is wrapped for several days and the patient is instructed to massage the penis for weeks.
