10 Facts you did not know about the penis

10 Facts you did not know about the penis

Smoking causes several diseases, including cancer. For the penis to be erect, a set of actions involving the brain, nerves, circulation, hormones, muscles and the erectile tissue itself is necessary. Studies have shown that the smoker has impairment in all of these participants. In addition, when men of the same age and with the same comorbidities are compared, those who smoke are more likely to suffer from erectile dysfunction.

2. Prostate diseases may be related to erectile failures

The prostate is a gland that is just in front of the bladder and its main function is to produce part of the semen. When the man grows older, the prostate gland changes. Some conditions such as benign prostatic hyperplasia (BPH) and prostatitis can make it difficult to empty the bladder and cause symptoms that interfere with the quality of the erection. Tadalafil, a known impotence drug, can also be used to treat BPH.

3. Erectile dysfunction may be a sign of future heart disease

Penile erection depends on good blood circulation. When there are constant failures and the cause is related to atherosclerosis (clogging of blood vessels), the problem may not be restricted to the penile circulation. There may be fat plaques (atheromas) in other arteries, including those that nourish the heart, the coronary arteries. Studies have shown that men who have suffered acute myocardial infarction have been living with erectile dysfunction about three years earlier.

4. Although not made with bone, the penis can fracture

The fracture of the penis can occur and is a medical emergency. When the penis is hard, hard, it is not possible to bend it. The fracture of the penis occurs exactly when a significant trauma causes the rupture of the layer that lines the corpora cavernosa. The most common mechanism is the sexual relationship where the partner stands over the partner, sitting on the erect penis. During movement, the limb moves and the partner's body forces the suddenly folding penis. Classically a popping occurs, the erection stops immediately and a large hematoma forms on the organ. The penis looks like an eggplant!

5. Keeping the penis flaccid gives work

That's right! In order for the penis to circulate just the amount of blood needed to nourish the cells, the brain constantly orders the muscles that surround the arteries and the wall of the corpora cavernosa to contract, limiting the flow of blood. On the other hand, when sexual arousal occurs, the brain understands that it must prepare the limb for a relationship and the order becomes relaxation of the muscles and consequent dilation of the vessels and spaces within the corpora cavernosa. The blood flow increases greatly and erection occurs.

6. Ejaculation control depends on training

The command of ejaculation occurs in the brain. Some areas of the brain concentrate specialized cells that are stimulated during excitation, and when a certain threshold is reached, the phenomenon of ejaculation happens. Ejaculate means to emit the semen. Usually ejaculation happens along with orgasm, which is the sensation of pleasure associated with the climax of sexual activity. Physiologically, ejaculation would be a reflex, that is, something involuntary (without control). Therefore, in the beginning of the sexual life, it traditionally happens quickly. With sexual maturation, man learns (training) to prolong pleasure and to exercise some control over the moment of ejaculation.

7. Peyronie's disease is named after a French doctor who described for more than 200 years a type of fibrosis that occurs in the body of the penis and causes different deformities during erection . Even today there are many questions about the causes of this fibrosis. It is believed that minor trauma would cause injuries to the lining layer of the corpora cavernosa and there would be exaggerated scarring that would eventually produce a fibrotic tissue that would limit the elasticity of one of the cylinders and cause tortuosity.8. Ejaculate back? Yes, it may happen.

Semen is released in jets forward during ejaculation thanks to a command of the brain that contracts and closes the prostate, at the same time as it pumps the posterior urethra through the rhythmic contraction of the surrounding muscles ( bulbous). So it's as if the prostate was the cannon's breech. For the "shot" to go forward, the prostate needs to close the entrance of the bladder. When it does not close completely, the semen goes backwards, that is, into the bladder. The so-called retrograde ejaculation most commonly occurs in individuals with diabetes mellitus, neurological diseases, after some prostate surgeries or with the use of medications to treat benign prostatic hyperplasia (such as tansulozine and doxasozine). All of the described conditions cause failure of the prostate at the time of ejaculation.

9. Testosterone has less relation to erection than you might think

The main male hormone, testosterone, is involved in many functions in the body. But, unlike popular belief, testosterone is not one of the major hormones involved in penile erection. Other substances have a greater participation. The history proves this in the reports of cases where the eunuchs (men castrated, without testicles) were able to maintain erections and sexual activity within the harem. On the other hand, testosterone levels relate more significantly to libido, to sexual desire. In addition, testosterone plays a key role during puberty in the development of male sexual characteristics such as coarse voice, hair distribution, penis growth, and so on. Sleeping poorly impairs sexual performance

Sleep quality interferes with various systems in our body. Poor sleepers find it harder to restore their energies to the next day. More recent studies have shown that those with obstructive sleep apnea, one of the most common dysfunctions among men who snore and present daytime sleepiness, have a detrimental effect on their sexual performance. When obstructive apnea is classified as severe, erectile dysfunction often occurs and even failure of erectile drugs to occur. On the other hand, men with sexual impotence and sleep apnea who did not respond to sildenafil had good erections with the drug when they used CPAP, a device that treats obstructive apnea.

Zika virus: WHO expects about 4 million infections and convenes emergency committee

The session aimed to inform countries of more details of the epidemic that struck Brazil and 22 other countries, with cases already confirmed. WHO Director-General Margaret Chan was present and stressed that WHO is deeply concerned about the rapid evolution of the situation for four main reasons: The possible association of zika infection with birth of malformed infants and syndromes neurological diseases, such as microcephaly - noting that the WHO still does not accept this causal relationship due to a lack of medical evidence, of proof Possible international dissemination of the virus due to the huge geographic distribution of the mosquito With this, Chan called an emergency committee for next Monday, February 1, to discuss the epidemic, the relationship with neurological syndromes and what can be done internationally to minimize the problem.
