Unconsciously, the summer is coming, and the temperature is gradually rising.While everyone takes out a variety of modern "weapons" to fight against the heat, have you ever thought about who is more afraid of hotness than us?That's right, that's our sperm.
High temperature injury sperm
The core temperature of the human body (that is, the body temperature measured through the rectum) is 37 ° C, while the temperature of the testicles is 2 ℃ -3 ℃ lower than the core temperature.Our scrotum can keep the testicles with the best temperature of sperm development of about 35 ° C by contraction and relaxation.And the temperature of the sauna is much higher than that of the body temperature. What impact does this have on sperm?
Many documents at home and abroad have pointed out that too high temperature is not good for sperm development.Excessive temperature can reduce the number of sperm (semen volume, sperm density), decreased activity (average path speed, curve speed, sperm head side sideline) Sperm, cone head sperm, non -fixed head sperm, empty bubble head sperm, double head sperm, neck and mid -range defect sperm, tail defect sperm, etc.), and tail defects, etc.), and induced reproductive apoptosis.
The mechanism that affects the sperm morphology may be: 1. The temperature of the sperm caused by the warmth causes the sperm morphology, so that the ejaculation of the sperm in the epididymis is accelerated and the sperm is accelerated and matured through the epididymis.2. The warmth of the reproductive system metabolism and biochemical changes cause the testicular sperm tissue to destroy, the testicular sperm ability decreases, causing sperm to die in the testicles a large number of deaths, testicular atrophy, and volume shrinkage, resulting in abnormal sperm morphology.
The relevant domestic research results also show that sauna is related to the abnormal sperm.In a comparison test of infertility patients with a sauna history and 369 infertility patients with a history of no sauna, researchers concluded that sauna affects sperm form, especially the number of non -fixed head sperm has increased.In another comparison test of 310 sample samples, 944 sample sample samples of sauna history, and 306 samples of sauna history infertility groups, researchers concluded that the conclusions were exactly the same as the previous test.
In fact, in addition to sauna, sitting posture, sedentary, and too tight pants can cause the scrotum temperature to be too high.In short, sperm is very easy to be injured, don't warm them.
Sauna = infertility?not necessarily
So, can sperm abnormalities caused by high temperature can be equal to male infertility painting?For example, does it often cause male infertility for sauna?There are many studies on this issue. The results show that sauna does affect the form of sperm, but this does not mean that sauna will cause infertility.
A study of the relationship between the University of Turkurus in Finland and the pregnancy of pregnancy stated that sauna does not affect the fertility of men.Coincidentally, an article written by Hanuksera and others published in American Medical Journal also explained that sauna does not affect fertility.The article also pointed out that the concentration of testicular hormones and gonad hormones in serum will not change after many sauna, and the concentration of prolactin of men and women will temporarily rise during the bubble sauna.Although some studies have shown that sauna will reduce sperm activity. However, in Finland, the birthplace of sauna, the sperm count of local men is very high, and the Finnish man makes women's pregnancy shorter than the British.Of course, this study is done in the birthplace of the sauna.
In addition to Finland's research, Mashron University in Thailand also conducted a test. Normal adult men at the age of 30 at the age of 30 after two consecutive weeks of sauna, the sperm activity decreased significantly, but after a week after the sauna, sperm was stopped. The degree of activity is restored to normal.They concluded that the increased temperature of scrotum caused by sauna will lead to a reduction in sperm activity. Fortunately, this reduction is reversible.
However, although there is no evidence that sauna will make you completely break the son -in -law, if you are currently making a plan, in order to increase the possibility of pregnancy, it is better to steam less sauna.
