With the improvement of living standards, people’s lives are becoming more and more irregular, male diseases are also the development trend of the young, affecting the physiological function of the man’s enemies are mainly the following kinds. No. 1 enemy – soft sofa sitting on a soft sofa for a long time, will bring serious harm to the male scrotum, this is because the normal sitting position is to the pelvis as a fulcrum, and the scrotum on the “safe and sound” to stay between the legs, but when you sit on a soft sofa, the fulcrum will sink, so that the legs will be unconsciously clamped. But when you sit on a soft sofa, the fulcrum will sink, so the legs will unconsciously clench, so that the scrotum pressure, impede blood flow. As a result, toxic substances released by the testicles accumulate in the body, thus affecting testicular health. In addition, the supply of nutrients is also interrupted, the testicular secretion of testosterone function is also weakened, how can the sperm “effective production”? No. 2 enemy – fitness bicycle Men to do fitness, health bicycle is the first choice of many people, but do not think that the longer the pedal, the healthier the body, because the time is too long, it will let the scrotum wear and tear, stones, and even swelling of the seminal vesicles and other problems, or even affect the physiological function. The main reason, the problem is out of the bike bench, because the bike bench is not only hard, and the front protrudes, men in the above pedal often inadvertently touch the scrotum, and long-term collision is not only nerve damage, scrotum flaccid, will also make the seminal vesicles and testicles network appears to be swollen phenomenon; the most serious is because of the impact of the blood circulation, so that the penile blood supply is insufficient to affect the function of the erection. Enemy No. 3 – heavy metals I believe that we are not unfamiliar with the physiological function of the killer, because heavy metals not only on the physiological function of the impact of the body’s health is also serious harm, among the lead, mercury, cadmium on the physiological function of the greatest impact. When the body ingests excessive lead, it will seep into the semen or eggs and stored, affecting the secretion of reproductive hormones, resulting in a reduction in the number of sperm, deformities, as well as reduce the chances of conception phenomenon. Mercury can lead to loss of physical desire and impotence, and in severe cases, it can make men infertile. Cadmium affects the secretion of sex hormones and causes damage to the liver and kidneys, so how can there be sexual interest? Enemy No. 4 – cigarettes “smoking is hazardous to health”, but also on the physiological desire to have the same negative impact. The reason why smoking leads to a decrease in libido is that the harmful substances contained in cigarettes will harden the blood vessels, hindering the flow of blood, leading to the emergence of the situation of inactivity. At the same time, it can make the penis not straighten and become curved, which affects normal intercourse.
