Occasionally erectile not smooth is not impotence

Men every seemingly casual nature behind easy erection, all hidden figure four big secret organization?A penile blood supply system, and the blood supplyPenile blood vessels that itself and blood flow for celebration in the penile erectile mechanism occupies an extremely important position, because of the nature of penile erectile is a response to a small vessels, the blood supply system out of order, of course, will cause bad penile erection.In addition, arteriovenous traffic when erect not to close also can cause impotence.Penis as a surprisingly natural hydraulic mechanical equipment, erection and retreat of physiological response characterized by an organ under the specific capacity of the great changes in hemodynamics of inflows and outflows.According to the size of the penis, erect when the increase in blood volume of about 80-200 ml.Penile erection, the penis artery expansion, enter the blood flow to the penis more than eight times larger than relaxed.When 120 ml/min (sponge body pressure increased to 75 mm hg) cause an erection, and once after erection maintain an erection of blood flow perfusion rate around 60% of the original, or 70 ml/min.Second, the sound nerve reflexPenile erection is a kind of reflection, the stimulation of nerve endings from a number of sensors and conditioning stimulation can cause y stem erectile reflex.Involved in controlling the erectile function of neural elements including up to the cerebral cortex, the penis neuromuscular terminal structure at all levels of the blood vessel walls.If the cerebral cortex, sexual center;Diencephalon, hypothalamus, subcortical centers;Lumbar di ministry within the spinal cord, with an erection and ejaculation central, but the breast lumbar and sacral center also have synergy, there is a close relationship between the central, central spinal cord and the sensory and motor nerve associated with reproductive organs.All acquired from cerebral cortex of conditional reflex sexual excitement, can spread to central subcortical centers and spinal cord caused y stem erect, called psychogenic erectile.Give y stem directly stimulate excitement cause erectile centre after the formation of the erection, called reflex erections.Two kinds of erection are located in the erectile tissue of the spinal cord central issue instructions, and by nerve transfer and cancel the order.Third, the normal endocrine functionAndrogen prompted the differentiation and development of the fetal period, more important is that it is after puberty sexual excitement, one of the key factors of erection.Such as androgen deficiency caused by illness, patients lose penile erectile ability and cause impotence, when added exogenous androgen can restore erectile ability, explains the critical role of androgen in the erection.Androgen, although not directly stimulating central, can improve sexual central excitability, sex central keep certain reaction ability, but how androgen affects adulthood sensory nerve has yet to be studied.Testosterone produced by the regulation of the brain, the hypothalamus.The brain is also a target organs of sex steroid hormone.Malignant stimulation in the human spirit factors through the advanced neural can influence the hypothalamus interference and endocrine regulation center, makes in the human body blood circulation, to maintain male sexual function of androgen levels often is in a state of imbalance, which is one of the cause of psychic impotence.People also notice the testosterone level is significantly lower, often accompanied by decrease low sex drive and impotence, and supplement testosterone symptoms can be alleviated.But the exact relationship between sex hormones and is still not clear.Fourth, the normal anatomyNormal physiological anatomy is the penis erection material basis.As a result of genetic or hormone levels, genital development, severe deformity, testicular fibrosis, testicular abnormalities, severe testicular trauma or removed, the penis cannot erect.In severe phimosis, severe varicocele, scrotal hydrocele, y capsule elephantiasis cases, influenced by the psychological and physical reasons, can also affect y ba erectile mechanism.In addition, if you have genital malformation of adult male with a fear of sexual performance, consciously avoid sexual life, the long down will cause impotence. male sex enhancement pills
