Number one competitor-soft sofa
Sitting on a soft sofa for a long time will cause serious damage to men's scrotum. This is because the normal sitting posture is based on the pelvis, and the scrotum is "safe" between the legs. However, when you sit on the soft sofa, the fulcrum will sink, so that your legs will be caught unconsciously, thus pressing the scrotum and hindering the blood flow. In this way, toxic substances released by testicles will accumulate in the body, thus increasing the impact on testicular health. 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?
The Second Biggest Competitor-Fitness Bicycle
When men go to the gym, a healthy bicycle is the first choice for many people, but don't think that the longer they step on it, the healthier they will be, because stepping on it for too long will cause scrotal abrasions, stones and even swelling of seminal vesicles, which will affect their physiological functions. 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 will not only damage the nerves, make the scrotum soft, but also swell the 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.
The third largest competitor-heavy metals
I believe everyone is familiar with this physiological killer, because heavy metals not only affect physiological functions, but also do serious harm to health, especially lead, mercury and cadmium. When the human body ingests too much lead, it will seep into semen or eggs and store them, which will affect the secretion of reproductive hormones and lead to the decrease of sperm number, deformity and pregnancy. Mercury can cause problems such as decreased physiological desire and inaction, and even make men infertile in severe cases. Cadmium can affect the secretion of sex hormones and cause damage to the liver and kidneys. Why are you interested in sex appeal?
The fourth biggest competitor-cigarettes
"Smoking is harmful to health" also has a negative impact on physiological desires. 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, the penis will not bend straight, affecting normal sexual intercourse.
