Chen Guangbiao's ice bucket challenges faking ice water immersion for 5 minutes to cause infertility

People's Daily, Beijing, March 20 (Reporter Zhao Jinghan) Recently, Chen Guangbiao admitted that the "Ice Bucket Challenge" he participated in was fake. The statement that "soaking in ice water for 5 minutes can cause infertility", which was exposed as fake, also attracted the attention of netizens. In this regard, the reporter asked relevant experts for confirmation.

Chen Guangbiao admits that the "Ice Bucket Challenge" is fake

Last year, the "Ice Bucket Challenge" was very popular. Chen Guangbiao, the always high-profile "China's first good", was not willing to lag behind. He posted two videos on his microblog, which showed that he had soaked in ice water below 0 ℃ for 30 minutes, and launched a challenge: if anyone surpassed him, he would donate 1 million yuan.

His behavior was soon questioned by people. According to media reports, Wen Deyuan, the director of the Hunan Institute of Sexual Health and the director of the Affiliated Hospital of the Hunan Institute of Sexual Health, believed that "soaking in ice water at about 0 ℃ for 5 minutes will cause infertility." Therefore, Chen Guangbiao's move must be fraudulent.

This question triggered a great discussion among netizens. Some netizens believe that Chen Guangbiao "practises martial arts in Shaolin, and his physique is obviously superior to that of ordinary people". The length of immersion in ice water is also related to individual differences. It is not possible to rely solely on rigid data to tell the truth, pointing directly at Wen Deyuan's anti-science under the banner of science.

Wen Deyuan insisted that the human body soaked in a mixture of ice and water at 0 ℃ for 30 minutes would seriously damage the reproductive system of natural people. If it is not corrected, it will lead to blind obedience of others and irreversible physical injury. To prove this, he conducted an experiment. In the affiliated hospital of Hunan Provincial Institute of Sexual Health, the medical staff organized a special "ice bucket challenge", with the challenger being mice. Results After 5 minutes, the seminal vesicles of 3 mice were frozen and lost their vital signs.

Recently, Chen Guangbiao finally admitted that the two ice bucket challenge videos released on Weibo were not soaked in ice water, but "performance art". "The truckload of ice was real, and the bucket of ice poured on my head was also real, but half of the hot water was put in the bucket in advance, and the temperature was about 50 ℃. The temperature in the bucket of ice water mixed with hot water was about 25 ℃, about the same as that in the hotel's swimming pool."

Immersion in ice water for 5 minutes may not lead to infertility

For the statement that "soaking in ice water for 5 minutes can cause infertility", the reporter verified it with Guo Jun, director of the andrology department of Xiyuan Hospital, Chinese Academy of Traditional Chinese Medicine.

Guo Jun told the reporter: "This statement is a bit absolute. The cold environment has bad stimulation on the testicles, may cause damage, and is bad for sperm quality. This is certain. But if you say that soaking in ice water for 5 minutes will lead to infertility, I don't think it is certain."

At the same time, Guo Jun said that in fact, too cold or too hot environment will stimulate the testicles of men, which may seriously affect the reproductive function. "The normal temperature of the human body is below 37 ℃. The testicular sperm production and sperm maturation need to be carried out in a temperature environment of about 35 ℃. If the constant temperature environment is damaged, it will be detrimental to sperm production and development, and affect sperm quality. In order to achieve constant temperature, the scrotum acts as the 'thermostat' of the testicle. The scrotum keeps warm during contraction and cools down during relaxation. However, the regulating function of the scrotum is limited, we think The height should not exceed 40-42 degrees. In comparison, cold is better than hot. For example, when sperm is frozen, it is minus 80 degrees. "

He cautioned that for men at the reproductive stage (preparing for pregnancy), try not to expose their testicles to overheating or supercooling. The maximum temperature should not exceed 40 ℃, and the low temperature should not be lower than 0 ℃. Especially during pregnancy preparation, hot baths and hot springs should be avoided.

In response to Chen Guangbiao's ice bucket challenge, Guo Jun said that we have no right to intervene in personal behavior, but we should not encourage actions with health risks.
