Electromagnetic radiation: long-term heavy exposure to electromagnetic waves, can sensitive male germ cell testis severely damaged, the occurrence of rupture of the nucleus and cytoplasm of rupture, resulting in impaired spermatogenesis, infertility.
The thermal radiation: heat radiation also contributed to the decline in sperm quality an important factor and common cause of testicular heat sensitive, testicular sperm production process suitable temperature is 35.5° . When the temperature 2° ~ 4° impaired spermatogenesis can occur when; testicular environment in which the temperature exceeds 45° for two hours, that will hinder the formation of sperm and sperm motility.
Nuclear radiation: nuclear radiation on the testis, the most powerful destructive effects can easily lead to male infertility. In the testis is the organ most sensitive organ to radiation is one of low doses of radiation are sufficient to significantly lower sperm quality, can cause temporary or even no sperm. 200 to 300 roentgen radiations can cause impaired spermatogenesis, 600 to 800 roentgen doses will enable the complete loss of spermatogenesis, loss of normal fertility.
X-ray: Studies show that high-dose X-ray can cause sperm abnormalities, reducing the number of low quality, affecting germ cell genes, so that future generations have a serious genetic effects, which cause fetal malformations, miscarriage , premature delivery, mental retardation and so on.

The tonsilloliths are calcifications that form in the crypts of the tonsil formed by calcium salts or in combination with other minerals and are usually of small size. Some tonsilloliths give the sensation of a foreign object in the throat. They can be a nuisance, but they are not, in general, dangerous. They are one of the causes of halitosis, […]
