"Smoking is harmful to health" and has a negative impact on sexual desire. The reason why smoking leads to the decrease of sexual desire is that harmful substances contained in cigarettes will harden blood vessels, hinder blood circulation and may lead to inaction. At the same time, medical research also pointed out that smoking also has an impact on the penis, which will make it stretch and bend, affecting normal sexual intercourse.
Black boy #2: Soft sofa
Medical research has found that sitting on a soft sofa for a long time will cause serious damage to men's scrotum. Because the normal sitting posture takes the pelvis as the fulcrum, the scrotum "safely" stays between the legs, but when you sit on the soft sofa, the fulcrum will sink and unconsciously clamp the legs, thus pressing the scrotum and hindering the blood flow. In this way, the toxic substances released by testicles will accumulate in the body, which will have a great impact on the health of testicles. In addition, the supply of nutrients is also interrupted, and the function of testosterone secretion by testis is weakened. How can we "effectively produce" sperm? Therefore, remember that soft sofas must not sit for a long time.
Black boy #3: Bicycle
When men go to the gym, a healthy bicycle is the first choice for many people, but don't think that the longer you step on it, the healthier your body will be, because stepping on it for too long will cause scrotal abrasions, stones, and even swelling of seminal vesicles, which will affect sexual function.
The main reason is that the problem lies in the bicycle stool. Because the stool is not only hard, but also prominent in front, men often accidentally touch the scrotum when stepping on it. Long-term collision not only damages nerves and softens scrotum, but also causes swelling of seminal vesicle and testis net. The most serious problem is that blood circulation is affected, and insufficient blood supply to penis will affect erectile function.
Black boy fourth place: metal
I believe everyone is familiar with this kind of sex killer, because heavy metals not only affect sexual function, but also cause serious harm to health, especially lead, mercury and cadmium.
Excessive intake of lead will seep into semen or eggs and store them, which will affect the secretion of reproductive hormones, leading to decreased sperm count, deformity and pregnancy. Mercury can cause problems such as decreased sexual desire and inaction, and even make men infertile in severe cases. Cadmium can affect the secretion of sex hormones and cause damage to liver and kidney. Why are you interested in sex appeal?
