As the summer heat approaches, people always do their best to prevent the heat. But many men have neglected one thing: to “cool down” the scrotum. The scrotum is most afraid of heat and humidity. The man’s “treasure trove” – the scrotum, the appearance looks like a deflated broken tire, which is mainly caused by the scrotum appearance of many very thick skin folds. The scrotal skin is very sensitive to external temperature. When the temperature is low, the smooth muscles of the scrotal meatus and the levator muscle contract to raise the position of the testicles, and the scrotal skin tightens into dense folds and retracts to the perineum to prevent heat dissipation, which helps to keep the heat in. On the contrary, when the external temperature rises, the smooth muscles and testicular muscles relax, and the testes descend and leave the torso, and the scrotal skin relaxes accordingly, increasing the area of heat dissipation and facilitating local heat dissipation. This is how the scrotum regulates the temperature inside the scrotum. Do not underestimate this ability of the scrotum, it is too important for human reproduction of future generations. This is because the temperature has a great influence on the sperm production process of the testes. The temperature inside the scrotum is about 2°C lower than the body temperature, which is the most suitable temperature for sperm production; too high a temperature, sperm production will be impaired, the testes are very unfavorable to the manufacture of sperm, or even completely stop, while the secretion of testosterone will also be reduced, it is possible to make the middle-aged male partial lack of androgen syndrome appear early, and these changes may lead to male infertility or sexual dysfunction. In fact, damage to the testicles caused by high temperatures in life is more common and easily overlooked. For example, prolonged systemic febrile diseases, long-term exposure to high temperatures (cooks, boilermakers, welders, blacksmiths, etc.), and even long-term sauna baths and tight underwear can raise the temperature of the testicles. The “heat” has killed too many men’s dreams of “heirloom” and made too many of them “extinct”. The modern male is sitting still for a long time, the scrotum is confined to a narrow space for a long time, it is difficult to breathe, its own temperature will rise. The skin of the scrotum is very loose, very thin, quite sensitive, if often in a hot and humid, airtight environment, plus the legs rubbing when walking, it is easy to produce on the abrasive eczema, scrotal eczema. The reason for scrotal eczema is complex, but it is generally believed that it is related to sweating, resulting in local skin impregnated with sweat, while the work and living environment is hot and humid, or wearing tighter or chemical fiber underwear is a very important triggering factor. The main symptom of scrotal eczema is the painful “itch”, especially from the original hot and humid environment, take off the pants to contact the cooler temperature, but also let people have to scratch it, so the more you scratch the skin the more injured, and then the skin becomes thicker and thicker, the skin becomes thicker and want to scratch, forming a vicious circle. This will not only fail to relieve the itch, but will also aggravate the condition, and in serious cases will affect sleep and work. If the bacterial infection becomes pus, it causes local inflammation and inflammation and swelling of the lymph glands. Due to the sensitivity of the site, many patients avoid treatment and delay the condition. Those who have these symptoms should not use drugs indiscriminately and should go to the hospital in time. When some people find itchy scrotum, they scratch it with their hands or scald it with hot water and strong soapy water, which actually leads to thicker skin and worsening of the condition, which is very wrong. For the treatment of scrotal eczema, eczema is related to allergies just like eczema in other areas, so any medication used to treat allergies can be used to treat scrotal eczema. Scrotal eczema must be treated with medication to get better. The scrotal skin is thin and tender and has a higher absorption capacity for topical medication than other parts of the skin, so it cannot be treated with strong hormones, but rather with weak to medium-acting hormones. Patients should choose different medications according to their condition. For patients in the acute stage, mild, non-irritating local treatment should be given, depending on the stage of the disease and the skin lesions; for patients in the chronic stage, while implementing local treatment, appropriate oral medication should be taken for systemic treatment, and in particularly serious cases, injections or infusions are needed. Some men also often find discomfort in their private parts during the hot and humid summer months, and can occasionally smell a bad odor and an increase in foreskin scale. This situation, every summer, the foreskin caused by inflammation and the increase in the number of patients, the weather is hot and humid, the foreskin is very easy to breed bacteria and fungi, etc., will stimulate the sebaceous glands within the foreskin to produce more foreskin scale, can produce odor, serious cases can produce foreskin glansitis. The actual fact is that you can find a lot of people who have a history of diabetes, so in addition to the usual attention to clean local hygiene, if you have recurring episodes of circumcision, it is advisable to have circumcision treatment. In the summer, men should pay particular attention to the care of the scrotum, which can be summarized as “two more and two less”: more activities, more opportunities for scrotal heat dissipation; less sitting, less tight underwear. Specifically, you should avoid prolonged exposure to high temperatures and try not to wear jeans; it is advisable for men to take off their outer pants and wear a loose, light and breathable cotton underwear after they go home; don’t sleep on your stomach to avoid squeezing your scrotum, if conditions allow you to sleep naked; take fewer saunas or hot baths; and take a break every hour when driving or cycling. In addition, patients should eat more fresh fruits and vegetables, take proper supplements of vitamin B2 and B6, eat less seafood, spicy and other stimulating foods, and also quit drinking. It is important to thoroughly clean the scrotal crevice and pay attention to keep it dry; it may be worthwhile to slightly sprinkle some prickly heat powder to absorb sweat.
