Researchers using advanced flow cytometric technology, after more than a year of experimental found that smoking can cause the male rats born fine function badly damaged, sperm to greatly reduce child ability and the results for further study of the dangers of smoking male corresponding offers clues.
According to introducing, the scientists are only 20 male rats on special poisonous tank, every day make them passive smoking sixty minutes (every ten to twelve a), eight weeks of take out after ten rats testis and epididymis of; Another ten rats in the "stop smoking" 48 days later, was also take out testis and epididymis.
They will testis and epididymis down into individual cells, from molecular level research rat sperm DNA change. Two groups of smoking rats and normal rats anatomy contrast, researchers found that: the first ten rats born of sperm cells, sperm are significantly lower than normal DNA maturity rats, and another ten only "stop smoking" rats born of pure function is only the first 10 recovery.
Experts think, sperm development is a fragile change process, in which any link may suffer from toxins to pure obstacle was violated. Cigarette smoke contains three thousand six hundred DuoZhong toxic chemicals and carcinogenic, teratogenic content, extremely easy interference of normal testis born fine process, cause semen quality drop, sperm to reduce child ability.
