Erection and mental stimulation connection

The molecular and clinical understanding of erectile function continues to gain ground at a particularly fast rate. Intensive research has yielded many advances. The understanding of the nitric oxide pathway has aided not only in the molecular understanding of the tumescence but also aided greatly in the therapy of erectile dysfunction. As a man ages or undergoes surgery, preventative therapies to preserve erectile dysfunction have begun. All clinical interventions derived their beginning in a full anatomical, molecular, and dynamic knowledge base of erectile function and dysfunction. In this chapter the components of erectile function will be explained. The penile erectile tissue, specifically the cavernous smooth musculature and the smooth muscles of the arteriolar and arterial walls, plays a key role in the erectile process. In the flaccid state, Erection and mental stimulation connection smooth muscles are tonically contracted, allowing only a small amount of arterial flow for nutritional purposes. The blood partial pressure of Erection and mental stimulation connection PO2 is about 35mmHg range. Sexual stimulation triggers release Erection and mental stimulation connection neurotransmitters from the cavernous nerve terminals. This results in relaxation of these smooth muscles and the following events:. The angle of the erect penis is determined by its size and its attachment to the puboischial rami the crura and the anterior surface of the pubic bone the suspensory and funiform ligaments. In men with a long heavy penis or a loose suspensory ligament, the angle usually will not be greater than 90 degrees, even with full rigidity. Three phases of detumescence have been Erection and mental stimulation connection in an animal study. The second phase shows a slow pressure decrease, suggesting a slow reopening of the venous channels with resumption of the basal level of arterial flow. The third phase shows a fast pressure decrease with fully...

The management of erectile dysfunction ED has changed dramatically in recent years, as advances in molecular biology have given us a better understanding of the erectile process as well as the pathophysiology of erectile disorders. Until relatively recently, however, most research in ED focused on peripheral neurophysiology and on the local tissues of the penis, leading to the development of highly effective treatments such as penile injections and sildenafil. There has, however, been growing interest in the role of the central nervous system CNS in the control of erectile function, and researchers have begun to develop medications that target these central mechanisms. Researchers began evaluating apomorphine as a potential treatment for ED in the mid s, and it is currently under review by the Food and Drug Administration. Unlike sildenafil, which acts only on tissues in the penis, apomorphine acts directly on the brain. In response to the development and impending availability of apomorphine as a centrally acting agent for ED, a consensus group known as the Working Group for the Study of Central Mechanisms in Erectile Dysfunction was formed in to examine how the brain and spinal cord control penile erections. Sachs of the University of Connecticut, R. Steers of the University of Virginia. The group met recently to discuss and review what is presently known about these mechanisms and to consider future areas of research. The following are some of our findings and conclusions. An erection is a carefully orchestrated series of events controlled by the CNS. We now know that the penis is under the complete control of the CNS, both during sexual arousal and at rest. As our Working Group colleague William D. Steers has noted, any disturbance in the network of nerve pathways that connects the penis and the CNS can lead to problems with...

The veins draining the bodies can't keep up, resulting in swelling. As the swelling reaches the limit of the penile skin, the penis becomes firm. The pressure of the spongy and cavernous bodies against the skin partially closes the veins, helping to maintain the erection. Erection continues until the signals from the brain stop, but erections are not consistent; waking and waning are normal, even during intercourse. Nocturnal erections occur during all male dreams regardless of what the dream is about , unless the man has physical problems this is the easiest way to determine if impotence is physical or emotional in nature. The so called "morning erection" is the result of being wakened during, or just after a dream; and it can be a very persistent erection. While a morning erection is not a sign of arousal, it's presents and the pleasurable sensations it can create may result in arousal. Men have only very limited control over their erections. During puberty the young man is often embarrassed by erection in public settings, but he gradually becomes able to suppress erections when the stimulation is mild. Likewise, it is impossible to "will" an erection, although sexual thoughts can cause erection. During prolonged foreplay a man's erection may go away; this is normal, and is not a sign of lessening interest. General health and physical exhaustion can affect erection; when very tired, a man may be able to have only a partial erection, but still be able to climax. Erection is lost in two stages; the initial stage is very quick, but usually leaves the penis firm enough to continue intercourse. The second stage is somewhat slower and is effected by a variety of things including age which tends to speed it , and arousal level before climax, with higher or...

When the blood vessels of the corpora cavernosa relax and open up, blood rushes in through the cavernosus arteries to fill them. The blood then gets trapped under high pressure, creating an erection. Sexual stimulation and friction provide the impulses that are delivered to the spinal cord and into the brain. Ejaculation is a reflex action controlled by the central nervous system. It is triggered when the sexual act reaches a critical level of excitement. It has two phases. Cleveland Clinic is a non-profit academic medical center. Advertising on our site helps support our mission. We do not endorse non-Cleveland Clinic products or services. How It Occurs The blood vessels in the penis relax and open up, allowing blood to fill them. Blood trapped under high pressure creates an erection. What is the anatomy of the penis? The penis is made up of: Two chambers called the corpora cavernosa, which run the length of the organ and contain a maze of blood vessels shaped like cavernous spaces like a sponge The urethra, or channel for urine and sperm, which runs along the underside of the corpora cavernosa Erectile tissue, which surrounds the urethra, two main arteries and several veins and nerves The shaft, the longest part of the penis The head glans , which is at the end of the shaft The meatus, or opening at the tip of the head where urine and semen are discharged How does an erection occur? An erection begins with sensory and mental stimulation. During sexual arousal, nerve messages begin to stimulate the penis. Impulses from the brain and local nerves cause the muscles of the corpora cavernosa to relax, allowing blood to flow in and fill the open spaces. The blood creates pressure in the corpora cavernosa, making the penis expand and creating...

Life provides turning points of many kinds, but the most powerful of all may be character-revealing moments. Verified by Psychology Today. Save Your Sex Life.

That means that the situation you are in may be contributing to your ED verses a biological cause. If the answer is yes then chances are your ED is situational. If you are not waking up with erections anymore, then your ED is most likely biologically based and seeing a Urologist or Family Practice Doctor for help would be appropriate. Having biologically based Erectile Dysfunction makes you are good candidate for medications such as once a day Cialis or Viagra. Something else to consider with your ED is your porn use. If you are masturbating to very stimulating porn on a regular basis then it might be difficult to get as aroused in the bedroom with your partner. Consider masturbating without technology as visual images in your head are less stimulating then watching something live. Another factor that contributes to ED is not having enough stimulation before beginning or attempting sex. Many men have a sexual script that is kissing for a minute or two and then trying to proceed to intercourse. As men age they require more stimulation up front to get and maintain an erection firm enough for sex. Engaging in some foreplay either on you or on your partner is a great way to get your arousal levels up and get...
