Inside the male scrotum, the temperature is a couple of degrees lower than inside the rest of the body. For some reason, sperm formation in mammals is impossible at higher temperatures. I had to move the production facilities to the "outdoor area" and carefully monitor the temperature.
Distinguish between the temperature of the internal environment of the body and the temperature of its skin. The temperature of the internal organs is different and depends on the intensity of the biochemical processes occurring in them. The liver has the highest temperature (up to 39 °). The temperature of the skin is much lower than the temperature of internal organs, therefore, when measured in the rectum, it is 0.5-0.8 ° higher than when measured in the armpit. The temperature of the human skin is not the same in its different parts: it is higher in the armpit, the temperature of the skin of the neck, face, trunk, extremities is slightly lower.
In humans, the temperature when measured in the armpit ranges from 36-37 °, on the hands and on the skin of the feet even lower (25-30 °) and the lowest on the skin of the toes (24.4 °).
