Lead Pollution can cause male infertility

A recent study by U.S.scientists found that lead contamination may result in male infertility.Had found high lead content in the environment is hazardous to animal fertility, it is the first time confirmed that lead can cause human male infertility.
High lead level in the semen,the receptor in the sperm head used to identify the surface carbohydrate of ovum will reduce,and the ability of combination with the ovum is even worse,sperm destroyed occurred prior to the arrival of the egg are more generally.
We should prevent lead poisoning in the diet, living habits,and so on.First of all, prints and newspapers can't be used for food packaging,when packaging food,the bags should be avoided contact directly with the food on the pictures, trademarks,, especially in contact with acidic foods; fruits and vegetables should be washed before consumption,and should peel the skin as much as possible to avoid pesticide residues in the composition of lead.Do not use leaded paint to decorate home wall, floor and furniture and so on, otherwise, once the paint chip off, lead paint can easily cause lead pollution in room.Select lead-free cosmetics, hair dyes and so on. In addition,do not walk near the road with many moving cars,as there exist high levels of lead invehicle exhaust and road surrounding soil.Diet should contain adequate quantity of high quality protein, such as eggs, lean meat, poultry, fish, soy beans and soy products, etc.Should select the vitamin-rich food, especially vitamin c is more important. Adequate vitamin c, not only complement the depletionto caused by lead and slow down the symptoms of lead poisoning, vitamin c can also combine with lead into the lower solubility lead salt of ascorbic acid to reduce lead absorption in the intestine,while vitamin c is also directly or indirectly involved in the process of detoxification, and promote the discharge of lead. Adequate vitamin e can resist peroxidationbe caused by lead , vitamin d can be passed on to influence the regulation of calcium absorption and deposition of lead. Vitamin b1, b2, b6, b12 and folic acid,etc.,have certain effects on improving the symptoms and to promote the restoration of physiological functions . Appropriately eat some natural foods which have a certain anti-lead and lead-drive functions. Protein contained in milk can be combined with lead into the insolubleformation, the calcium contained in it can prevent the absorption of lead.
