For the treatment of erection disorders in men, depending on the reasons for their development, various techniques are applied. One of them is the use of local negative pressure (LOD-therapy) in the form of effects on the cavernous body of the penis. This therapeutic technique was proposed by sexologist R.V. Beleda, she underwent appropriate clinical trials and received copyright certificate.

The principle of operation and justification of LOD

The therapeutic mechanism of local negative pressure is a positive effect on the cavernous body of the genital body due to the stimulation of blood flow in them. This is achieved by creating a negative pressure (vacuum) in a special tube (minibar chamber), which is usually made of plexiglass. The base of the tube is tightly pressed to the pubic joint, the penis is placed into it, and then gradually with the help of a special pump air is pumped out of it (see Fig. 1). This creates a negative pressure (on average 150-300 mmHg below atmospheric pressure), the skin, tissues and cavernous bodies of the penis are mechanically stretched, which leads to effects on various nerve receptors (chemo-, baro-, and thermoreceptors) tissues.

In addition to enhancing the intensity of blood flow in the cavernous bodies, LOD-therapy additionally has several physiological effects, which include:

  • a higher degree of saturation of the tissues of the penis with oxygen from the blood due to the low partial pressure in them;
  • improvement of the functional state of the small capillaries of the tissues of the penis, their disclosure and the increase in blood flow to them;
  • increasing the intensity of metabolic processes (metabolism) in the tissues by improving blood circulation, lymph circulation and extracellular fluid;
  • local temperature increase in the tissues of the penis under the influence of negative pressure, it contributes to a better absorption of oxygen and nutrients from the blood and extracellular fluid;
  • an increase in the number of nerve impulses from various receptors in the tissues of the penis, which enter the corresponding centers of the spinal cord and then the brain, leading to a reflex development of erection.
These therapeutic effects after LOD help to improve erection in men , as well as the functional state of the testicles, their appendages and prostate gland.

Therefore, the use of local negative pressure for the penis is physiologically justified for various disorders of functional activity, including psychogenic in nature.

Indications for LOD-therapy

The application of the method of exposure to local negative pressure on the penis is shown for various functional disorders and somatic pathology, which include:

  • circulatory disorders in the tissues of the penis, primarily related to the insufficiency of the functional activity of the cavernous sphincters, which are responsible for their sufficient filling with arterial blood;
  • psychogenic erection disorders that develop as a result of various neurotic states, the emotional experience of a man associated with the expected possibility of failure in relation to full-fledged sexual intercourse ( anxiously waiting for sexual failure syndrome );
  • initial debut forms of potency disorders, which were revealed for the first time;
  • chronic inflammatory processes in the prostate gland (chronic prostatitis ), testicles and seminiferous tubules;
  • certain forms of impaired potency in men against the background of age-related involution (extinction of functional activity) of the reproductive system;
  • diagnostic effect of local negative pressure on the male penis to determine the causes of the development of functional vascular disorders;
  • Peyronie's disease - the curvature of the penis due to fibrotic changes in the cavernous bodies, more deformity occurs during erection, which can also lead to the appearance of pain;
  • copulatory dysfunction (impossibility of sexual intercourse) in men after undergoing surgical surgery on the urethra (urethra);
  • comprehensive sexual rehabilitation of men after postponed adenomectomy (removal of hypertrophied, enlarged part of the prostate gland);
  • problems with erection after suffering cavernitis (inflammation of the cavernous bodies);
  • intermittent priapism - periodic painful erections of the penis, which often develop at night;
  • carrying out comprehensive rehabilitation measures after vascularization (treatment aimed at improving blood circulation) of the penis.

LOD-therapy is also performed as a rehabilitation measure after suffering various plastic surgeries on the male penis, including various congenital malformations (hypospadias, epispadias, micropenis).

Contraindications for LOD-therapy

LOD-therapy is a medical procedure, which is possible only after the exclusion of possible contraindications. They are conventionally divided into general and local (local) contraindications.

General contraindications include various pathological conditions of the whole body of a man:

  • feverish conditions (intoxication of the body and fever) with various infectious, bacterial or viral pathologies;
  • malignant or benign neoplasms (tumors) of various localization in the body, including prostate adenoma;
  • hypertension (long-term increase in blood pressure) of the 3rd stage of the course;
  • various pathologies of the heart in the stage of decompensation, accompanied by the development of heart failure;
  • atherosclerosis (deposition of cholesterol on the walls of blood vessels with the formation of atherosclerotic plaques that reduce their lumen) of the vessels of the brain or heart;
  • peptic ulcer disease (formation of a mucosal defect) of the stomach or duodenum;
  • chronic somatic pathology of internal organs in the acute stage (glomerulonephritis, pancreatitis, hepatitis);
  • diseases of the blood system, especially accompanied by a decrease in its clotting and the development of a tendency to bleeding, as well as taking anticoagulants (drugs that reduce blood clotting);
  • Erectile dysfunction of the penis caused by various pathologies of the internal organs, cardiovascular or endocrine system.

Local contraindications to the LOD include various pathological changes in the penis, the tissues of the pelvic region, as well as internal genital organs:

  • pronounced varicose veins (the formation of extensions in the form of nodules) spermatic cord 2 or 3 degrees of severity;
  • inguinal hernia ;
  • thrombophlebitis (inflammation with intravascular formation of blood clots) of the veins of the pelvic region and lower extremities;
  • acute or chronic pathology of the testes and their appendages of various origin;
  • inflammatory processes of the pelvic organs;
  • phimosis (narrowing of the foreskin of the head of the penis) or paraphimosis (an emergency condition that involves pinching the head of the penis with the foreskin behind the coronary sulcus).
Before starting LOD-therapy, the doctor must be convinced of the absence of contraindications.

Method of LOD-therapy

LOD-therapy is carried out in a medical institution under the supervision of a physician. Before the procedure, the male penis, with a pre-dressed condom, is placed in the mini-bubble chamber tube, while the scrotum and testicles must remain outside. Then the doctor connects the tube to a special device with a pump for air dilution and a regulator to control the negative pressure indicator and turns it on. During the procedure, the doctor monitors the general condition of the patient, and periodically asks questions about his state of health. He necessarily pays attention to the condition of the skin of the penis, which becomes hyperemic (acquires intense red staining) due to an increase in blood flow. Also during the procedure a passive erection of the penis is possible.

Modern devices for LOD-therapy are equipped with special fuses that prevent the air in the minibar chamber from being diluted above a certain value. In case of deterioration of the patient’s general condition, the appearance of severe pain in the penis, the procedure is temporarily stopped. The vacuum of the air as a whole lasts 15-20 seconds, then the pressure levels off, after which the session is repeated, up to 15 sessions of LOD-exposure are performed in one procedure. The course of treatment can include up to 20 procedures of LOD-therapy, on average they are carried out 3 times a week, the last 8-10 days can be performed daily.

Possible complications

LOD procedure is low-impact, therefore, when properly applied, it rarely leads to complications, which include:

  • Edema and hyperemia (redness) of the foreskin.
  • Point hemorrhages in the skin due to damage to the blood vessels of the microvasculature.

In general, LOD-therapy procedures lead to a noticeable improvement in erectile function, an increase in libido in most men.
