The study was conducted upon the prior consent of the Ethics Committee of the UWM in Olsztyn (10/2020), according to the World Medical Association Declaration of Helsinki. The participants confirmed that they did not take any medications or nutritional supplements, were in good health, and had no history of blood diseases or diseases affecting biochemical and biomechanical factors. The students who agreed to participate in the study (47 men) were notified by e-mail and a text message whether they met the inclusion criteria and were provided with the date of final recruitment. The prospective participants were informed about the purpose of the study during a meeting held 2 months before the experiment at the University of Warmia and Mazury (UWM) in Olsztyn, Poland. The study was conducted in 2020 on 30 male volunteers aged 19–26 years (22.67 ± 2.02). Depending on the duration and strength of heat stress, cell death may also occur 11,12. Heat stress decreases the sperm motility or even density, therefore increases sperm deformity and the infertility rate among boars . Part of infertile men have symptoms that their temperature of scrotum is higher than that in males with normal reproductive function, and their sperm will lose qualities gradually as the temperature increases . The normal spermatogenic process needs the lower temperature in scrotum than in body. Recent research has shown that different treatment strategies should be used for testicular heat stress. Heat stress can affect most cell types in the testis, including spermatids, spermatocytes, spermatogonial stem cells, Sertoli cells, and Leydig cells. Heat stress of Leydig cells mainly effects the hormone secretion of Leydig cells . The most vulnerable cells to heat damage in humans and rats are the zygotene and pachytene spermatocytes and early round spermatozoa . Ball temperature doesn’t just affect testosterone. While you want to avoid heat, extreme or prolonged cold can cause numbness or discomfort. A 3–5 minute cold shower in the morning not only invigorates your body but directly impacts the testes. The testicles are designed to stay a few degrees cooler than the rest of the body. When it comes to optimizing male hormone levels, most guys jump straight into supplements and workouts. This happens because cold water immersion (CWI) can disrupt anabolic signaling and recovery, potentially leading to smaller strength and muscle size gains over time.

However, it’s important to see cold plunge therapy as just one piece of the overall wellness puzzle. If somebody says 10 minutes in the cold is good, then we'll do 20 minutes because it's going to be twice as good. Every single individual needs to learn about their own body's response to cold and their limits. However, cold-water immersion doesn't appear to negatively affect endurance training in the same way. For those engaged in resistance training, cold water may turn down the molecular signaling pathways that are normally activated after exercise. However, there is a group of people who consider that during colder months, this level improves. Once you feel more at ease, you can gradually extend the duration or lower the temperature, depending on your comfort level. For those new to cold plunges, it’s important to ease into the practice with care. To get the most out of cold plunges, plan them carefully to align with your fitness and recovery goals. Heat stress may lead to lower testosterone levels, affecting your overall energy and muscle function. Studies such as one from the American Journal of Physiology reveal that elevated scrotal temperature can decrease testosterone levels. Increased scrotal temperature impairs Leydig cells, which are responsible for testosterone production. The most optimised natural testosterone booster ever developed. Some evidence even suggests our testosterone can drop. The body controls this by using the cremasteric reaction to determine whether the balls are positioned low towards the abdomen or high. After a "cooling-off" period of several months following the study, all participants recovered fully. By week four, the sperm counts of all the volunteers were drastically reduced. A study in Fertility & Sterility asked men to wear specially-designed underwear hours per day for a period of 4 months. It's interesting to note that meat factory workers who are exposed daily (-40o C) showed a drop in serum testosterone as well. Testosterone influences body temperature regulation by affecting the hypothalamus, a part of the brain that controls body temperature. It is responsible for various functions in the body, including body temperature regulation. Testosterone is a hormone that plays a crucial role in men’s health. Antioxidants act to inhibit the generation of oxidative stress, maintain cell homeostasis, and promote cellular resistance to the high-temperature environment. These drugs target different cells and proteins in the testis, and most of them reduce cell damage by promoting HSP family expression and relieving oxidative stress.
