As the saying goes, “people depend on their clothes”, everyone wants to look beautiful or handsome, so the requirements for clothing will be higher, and will choose some clothes that make them look beautiful, sexy and handsome. But when people focus on the appearance of beautiful, but ignored a problem, whether it will have an impact on health? Some sexy clothes, in fact, on the “sexual well-being” will have a negative impact. Many people because of the desire to be sexy, may damage their sexual health, affecting the quality of married life. The fact that the perineum is too tight, poorly ventilated, easy to breed bacteria, easy to lead to urinary tract infections, will also affect fertility. Although jeans are trendy, fashionable and wearable, it is not advocated to wear them for a long time, especially in the summer, it is best not to wear them. The fabric of the jeans is thicker, heat and ventilation is poor, long time wear will lead to male testicular area temperature rise, the adverse effects on fertility is great. The number of infertility patients is increasing day by day, of which the decline in sperm quality is one of the important reasons. Both research and clinical studies have found that high scrotal temperatures in men are not conducive to sperm survival. In particular, men with idiopathic infertility or varicocele have testicular temperatures that may be higher than the average person, and these men are more unsuitable for wearing tight-fitting clothing, so it is important to draw attention to this.
