Does beer reduce libido?

Patient's question:

Gender: Male
Age: 39
Current general condition: Good.
Doctor, my husband is 39 years old this year, and his health condition is basically good. However, there is a habit that makes me worry about him, which is: he drinks beer every night. Sometimes he drinks a lot, and sometimes he drinks a little. This habit has been going on for several years. Recently, I feel that his libido hasn't been as good as before, and I wonder if it's related to this habit. I heard that beer can lower libido, but I don't know if it's true. Is drinking beer often harmful to his body? What are the harms? Thank you for your answer!

Doctor's answer:

Hello, alcohol generally has adverse effects on the human gastrointestinal tract, heart, liver, and kidneys, leading to the occurrence of certain diseases, and excessive consumption of beer also carries the risk of gout. If beer is consumed chilled, the harm is even greater. The temperature of chilled beer is 20—30℃ lower than the human body temperature. Drinking large quantities can cause a rapid drop in the temperature of the gastrointestinal tract, a decrease in blood flow, leading to physiological dysfunction and impaired digestive function. In severe cases, it may even trigger life-threatening emergencies such as spasmodic abdominal pain, diarrhea, and acute pancreatitis.
Beer also does little to help with cooling down. As early as 1924, studies abroad examined the effects of beer on the human body. When each person consumed two bottles of medium-strength beer on an empty stomach, their reactions were similar to drinking 100 milliliters of strong liquor. The participants experienced a sudden increase in heart rate, an 88% increase in pulse frequency, a 38% decline in arm response ability, a 26% decline in static standing ability, a 14% decline in coordination, and a 5% decline in cognitive function. It is clear that beer, like strong liquor, increases physical consumption, making it easier to feel fatigued, and drinking beer intensifies thirst and sweating. Not only does it fail to achieve the purpose of cooling down, but it also affects cognitive function and work efficiency, potentially even causing errors and accidents at work.
