In the era of urban traffic congestion and advocacy of environmental protection and health, cycling is a great way to travel and exercise, but if the seat is not appropriate, it can indeed lead to perineal discomfort and even prostate disease. Therefore some people write articles suggesting less or no bicycling, I do not agree with this view. If you choose the right bicycle seat and adjust the angle, you can avoid the problem completely. The prostate is located at the bottom of the pelvis, near the perineum, between the anus and scrotum, and only a few centimeters from the skin, exactly where the force is applied to the front of the bicycle seat. The prostate is a chestnut-sized gland that surrounds the urethra, and most of the semen is prostatic fluid secreted by the prostate. If the bicycle seat is overly compressed and stimulated by the prostate, it will swell and congest, and the prostatic fluid will not be excreted properly, leading to prostate disease. These conditions are likely to occur among cyclists and racing bicyclists because the handlebars of racing bicycles are lower than those of ordinary bicycles, and cyclists have to lean over to ride, which makes the perineum more forward and increases the pressure on the prostate, and the racing seat is narrow, which also increases the force per unit area of the perineum. A few bicycle manufacturers have taken note of this problem by making the center of the seat concave or hollowed out to reduce pressure on the perineum, leaving the real force on the back sides of the seat, which corresponds to the position of the sciatic tuberosity. I have only seen few such products in the market. I hope that manufacturers pay attention to this situation. If you can’t buy such a car seat, friends can lower the front of the seat, so that the body’s center of gravity shifts to the rear, which can also reduce the pressure on the prostate. If you’ve got a lot of time, you’ll be able to get a lot of money for your business.
