Both ED and low testosterone (hypogonadism) increase with age. The incidence of the latter is 40% in men aged 45 years and older.  Testosterone is known to be important in mood, cognition, vitality, bone health, and muscle and fat composition. It also plays a key role in sexual dysfunction (eg, low libido, poor erection quality, ejaculatory or orgasmic dysfunction, reduced spontaneous erections, or reduced sexual activity). 
Erectile dysfunction affects millions of men. Although for some men erectile function may not be the best or most important measure of sexual satisfaction, for many men erectile dysfunction creates mental stress that affects their interactions with family and associates. Many advances have occurred in both diagnosis and treatment of erectile dysfunction. However, its various aspects remain poorly understood by the general population and by most health care professionals. Lack of a simple definition, failure to delineate precisely the problem being assessed, and the absence of guidelines and parameters to determine assessment and treatment outcome and long-term results, have contributed to this state of affairs by producing misunderstanding, confusion, and ongoing concern. That results have not been communicated effectively to the public has compounded this situation.
Patients should continue testosterone therapy only if there is improvement in the symptoms of hypogonadism and should be monitored regularly. You will need periodic blood tests for testosterone levels and blood tests to monitor your blood count and PSA. Testosterone therapy has health risks, and thus doctors should closely monitor its use. Testosterone therapy can worsen sleep apnea and congestive heart failure.
In order to establish whether normal erections are occurring overnight (nocturnal erections), the doctor may organise nocturnal penile tumescence (NPT) testing. This involves wearing a monitor overnight in your own home. The data from this monitor is then assessed to analyse how often erections occurred, how long they lasted, and how rigid and large the penis was during the erections. If NPT testing is normal, the cause of erectile dysfunction is usually psychological. If not, further testing of the blood flow in the genital area may be required to see if there is blockage or leakage. The doctor may also organise a blood test of levels of hormones such as testosterone, prolactin and thyroid stimulating hormone to see if these are contributing to the erectile dysfunction.
Stiffy Solution: Obviously, no one should ever go off a prescribed med without consulting with a doctor. But there are erection-friendly alternatives to nearly every daisy-wilting medicine listed above. And your dude shouldn't let embarrassment keep him from talking to his GP about this — doctors are well aware that erectile difficulties are a possible side effect for all of these medicines; they just don't know which patients will experience what side effects, so they're waiting for you, the patient, to bring it up.
One thing you need to know. When you are experiencing anxiety, you get a stress response. You can read more about this here. A stress response is what you automatically feel, say, if a fight broke out near you. Your body gets ready to protect itself. During a stress response, blood is diverted away from less important areas to help your heart beat faster.
Heart disease isn't the only risk. ED is also a predictor of stroke, because when the arteries are narrowed there is more chance of a blood clot, which can spread to the brain. It is also a common complication of diabetes. But embarrassment stops people seeking help, says Jackson. "We need to encourage men to talk to their spouses about this problem, instead of making an excuse to avoid sex.
*All medications have both common (generic) and brand names. The brand name is what a specific manufacturer calls the product (e.g., Tylenol®). The common name is the medical name for the medication (e.g., acetaminophen). A medication may have many brand names, but only one common name. This article lists medications by their common names. For information on a given medication, check our Drug Information database. For more information on brand names, speak with your doctor or pharmacist.
Sexual stimulation causes the release of neurotransmitters from cavernosal nerve endings and relaxation factors from endothelial cells lining the sinusoids. NOS produces NO from L-arginine, and this, in turn, produces other muscle-relaxing chemicals, such as cGMP and cyclic adenosine monophosphate (cAMP), which work via calcium channel and protein kinase mechanisms (see the image below). This results in the relaxation of smooth muscle in the arteries and arterioles that supply the erectile tissue, producing a dramatic increase in penile blood flow.
Additionally, the physiologic processes involving erections begin at the genetic level. Certain genes become activated at critical times to produce proteins vital to sustaining this pathway. Some researchers have focused on identifying particular genes that place men at risk for ED. At present, these studies are limited to animal models, and little success has been reported to date.  Nevertheless, this research has given rise to many new treatment targets and a better understanding of the entire process.
Everyone knows that regular exercise is good for the body and the mind, and in many cases, exercise can be good for relieving stress and helping men’s bodies produce more testosterone. In some cases, however, exercise can be detrimental. This is the case in cycling as long and regular rides can cause the nerves in the perineum to be compacted, leading to a loss of feeling in the penis and/or testicles. Over time, this nerve compaction and damage may lead to either erectile dysfunction or ejaculatory dysfunction.
Since you’re the talker, this is an argument that you’re going to have to win. Really let him know that you feel insecure and unloved when he doesn’t say “I love you.” Tell him it makes you worry about how he really feels when he doesn’t say anything. Tell him that it hurts you that he won’t step the slightest bit out of his comfort zone to say three words that would make you feel so much better. Let him know this doesn’t mean he has to suddenly get all lovey-dovey and give you a cheesy nickname and lay on the sugar so sweet your teeth rot, you adorable little honeybee — because then you might both puke. (I just threw up a little in my mouth myself while typing that.) But that’s not what you’re asking. Let him know you just want an “I love you” now and then. That’s not unreasonable. He doesn’t have to go overboard and you may not get the constant affirmation you prefer — but you can both compromise.
Dr. Liou says that some men come to him after getting a prescription from their primary care doctors, claiming that the drug doesn't work. Sometimes it's because they used it incorrectly. "The biggest misconception is that these drugs are an on/off switch for erections," Dr. Liou says. But the drugs don't work well without sexual stimulation. "During that time, you need to be with your partner and have foreplay," Dr. Liou says. "Don't take it, do the taxes or the dishes, and then meet at the bedroom thinking you'll be ready to go. It's not like that."
By contrast, psychogenic impotence typically is abrupt in onset, often in relation to psychological trauma, and may wax and wane. Patients with psychogenic impotence may have total erectile failure with one partner but not another, or be impotent during sexual intercourse but not during self-stimulation. Normally occurring spontaneous erections in the morning suggest psychogenic rather than organic causes for impotence.
Uncooperative boners might be related to low testosterone, which could be caused by anything from being overweight or stressed to having a chronic health condition, says Paduch. And in men who have taken anabolic steroids, it's not uncommon for them to end up suppressing their natural testosterone production. If you abuse it over a long period of time, you can really mess with your natural testosterone levels, as well as your fertility and erectile function, he says.
The pathogenesis of organic ED is related to dysfunction of the endothelium. Endothelial cells can become injured through a variety of mechanisms, most of which cause oxidative stress on the tissues. Many of these causes of oxidative stress are related to lifestyle issues which lead to hypertension, diabetes and dyslipidaemia (figure 1). Endothelial cell dysfunction results in reduction of endothelium-dependent vasorelaxation as well as increased adhesion of leukocytes to the endothelium. Endothelial cell injury then leads to a variety of sequelae, including ED, other types of vasoconstriction, atherosclerosis and thrombus formation.18
I am a woman who is currently in menopause. My sex drive has increased and i believe that it can equate to a teenage boy. My s.o. has erection dissatification. He can not penetrate. He prefers oral. He will become erect and orgasm. He works very hard to please me but sometimes I want intercourse. It makes me feel like he isnt attracted to me. I have been with him for quite some time and believe he has always had this problem. I dont understand why. I understand when you say that your wife has no interest. It can be hurtful.
Penile implants: This treatment involves permanent implantation of flexible rods or similar devices into the penis. Simple versions have the disadvantage of giving the user a permanent erection. The latest (and most expensive) device consists of inflatable rods activated by a tiny pump and switch in the scrotum. Squeezing the scrotum stiffens the penis, whether the person is aroused or not. The penis itself remains flaccid, however, so the diameter and length are usually less than a natural erection, and hardness is lacking, although it's sufficient for intercourse.
The 4 ED medicines we prescribe – Generic sildenafil 20 mg, Viagra (also sildenafil), Cialis (Tadalafil), or Levitra (Vardenafil) - are generally safe but shouldn’t be used as recreational drugs. They’re meant to treat a medical condition and can cause serious side effects including but not limited to an erection lasting more than four hours, sudden loss of vision in one or both eyes, and sudden decrease or loss of hearing.
Obviously, there are worse problems than a guy saying "I love you" too often, but if it's a problem, it sounds like the two of you need to have a long conversation. You need to understand why he likes to say it so much: Is it because he's insecure or hoping to comfort you or just breathlessly in love? (Or some combination of the three?) And he needs to understand how it makes you feel. So, if it really bothers you, tell him why.
The first step in treating the patient with ED is to take a thorough sexual, medical, and psychosocial history. Questionnaires are available to assist clinicians in obtaining important patient data. (See Presentation.) Successful treatment of sexual dysfunction has been demonstrated to improve sexual intimacy and satisfaction, improve sexual aspects of quality of life, improve overall quality of life, and relieve symptoms of depression. (See Treatment.)
Erectile dysfunction may be an unpleasant condition that no one really wants to talk about, failing to acknowledge it won’t make the problem go away. Your best defense against health problems like this is to learn everything you can about it so you can tackle the problem at the root. If you’re ready to stop living in embarrassment about your sexual function, become an advocate for yourself and your own health and talk to your doctor.
Stiffy Solution: Frustratingly enough, the only solution to exhaustion-based impotence is to get some rest, which is obviously difficult (or your dude wouldn't be having this problem in the first place). But if your guy has been resistant to getting help for his insomnia or asking for different hours at work, the inability to get his nine iron out on the putting green might be the thing that finally motivates him to make a life change. So, at least there's that.
Think of erectile dysfunction as your body’s “check engine light.” The blood vessels in the penis are smaller than other parts of the body, so underlying conditions like blocked arteries, heart disease, or high blood pressure usually show up as ED before something more serious like a heart attack or stroke. ED is your body’s way of saying, “Something is wrong.” And the list of things that cause erectile dysfunction can include:
