The official name for impotence should be called male erectile dysfunction. Male erection is a complex process involving multiple brain, hormonal, emotional, neurological, muscular and vascular issues. Erectile dysfunction may be related to 1 or more of these causes. There are numerous causes of erectile dysfunction, which can be classified as psychological erectile dysfunction and organic erectile dysfunction, of which organic erectile dysfunction is the most common, mainly including vascular, neurological, endocrine, diabetic, penile cavernous fibrosis, etc. The general people say that the tonic is only for the case of loss of sexual desire, energy, etc. Once the medical definition of impotence is reached because of organic lesions, the effect of the tonic is very limited, and even some products of unknown composition will cause adverse effects on the body, it is recommended to take medical formal treatment. The main treatment methods are: General treatment. Change of poor lifestyle, prevention and control of high-risk factors, such as increased exercise, weight loss and drugs that can cause erectile dysfunction (ED), active treatment of diabetes, hypertension of the original law of the disease. Endocrine therapy. If testosterone secretion is not enough to cause primary testicular disease or secondary to pituitary, hypothalamic disease, as well as middle-aged and elderly late gonadal dysfunction, testosterone supplementation therapy can be taken. Psychotherapy. For patients with obvious psychiatric disorders, psychosexual treatment can be performed alone or in combination with other treatment modalities. However, the time required for psychosexual treatment and its efficacy are uncertain. Pharmacotherapy: First-line therapy phosphodiesterase 5 is an enzyme widely distributed in penile cavernous tissue that hydrolyzes cyclic ornithine phosphate (cGMP). Inhibition of PDE5 activity can block cGMP hydrolysis and increase its concentration, inducing relaxation of penile vascular and cavernous sinus smooth muscle, which can lead to an increase in penile arterial blood flow and induce penile erection. The current highly selective PDE5 inhibitors, sildenafil, tadalafil and vardenafil, etc. Vacuum negative pressure device therapy. This is a second line of clinical treatment. When using negative pressure device, a negative pressure ring is placed at the root of the penis to stop blood return, and the negative pressure acts on the penile corpus cavernosum to attract blood into the penis, resulting in passive erection. Penile cavernosal drug injection therapy. It is also a second-line therapy. Vasodilating drugs such as prostaglandin E1, poppyrine, and phentolamine are injected into the penile corpus cavernosum to induce an erection through local vasodilating effects. However, the dosage of drugs used and the method of drug injection must be determined under medical supervision to avoid serious complications. Surgical treatment with penile erectile device implantation. This is a third-line clinical treatment. There are two types of erectors to choose from, a flexable (semi-rigid) and an expandable erector (two, or three piece set). Most patients prefer the three-piece expandable erector because it provides a more “natural” erection, but has the disadvantage of mechanical failure and other complications, and is more expensive. The two-piece prosthesis has a lower incidence of mechanical failure and is simpler to implant. So, what the people call impotence supplements are only some cases of reduced libido and low energy, the medical concept of impotence is more serious than these cases, and can not rely on the so-called supplements, but only through regular treatment.
