Ozone Exposure Lower Quality of Sperm


Jakarta, sperm quality is affected by many things, from food eaten, physical activity undertaken, to environmental influences. Researchers found that exposure to ozone in the atmosphere also affect the process of sperm development in men.

A study of men who live in Los Angeles found that exposure to ozone can reduce sperm quality. The study, published in the journal Environmental Health Perspectives this could add to the understanding of the causes of infertility in men.

This study analyzed the semen samples collected from a sperm bank in Los Angeles and compare it with the air quality.

The researchers found that exposure to high ozone levels near the homes of donors adversely affect semen quality. The impact of pollutants were found capable of affecting the entire development cycle of sperm in the body (spermatogenesis).

"We found an inverse relationship between ozone exposure and sperm concentration at all points studied. Our data show that sperm are vulnerable to toxic exposure in the entire period of spermatogenesis," said the researcher, Rebecca Z. Sokol as reported Altpenis, Monday (01/23/2012).

This study also analyzed other pollutants such as nitrogen dioxide, carbon monoxide and other fine particles. Each of these air pollutants is believed to affect sperm production, but no affect sperm density.

What causes the ozone mempu reduce sperm production remains unclear. Exposure to ozone is known to cause oxidative stress is known to interfere with testicular function and sperm.

Exposure to ozone can cause an inflammatory reaction, both in the male genital tract or form toxic chemicals that circulate in the body. Both could be expected to cause a decrease in sperm concentration.

"Many of the findings that demonstrate the potential hazards of the environment on the reproductive system. Some of them reported a decline in sperm counts in certain industrialized countries. The validity of these findings is still reaping the controversy. But most researchers agree that the decline in semen quality may be associated with the location geographically, "said Sokol.

Jakarta , smoking menthol may pose a risk of stroke is greater than other types of cigarettes, especially for non-smokers and women. Researchers from Canada found the risk of stroke for smokers of menthol two times larger than a regular cigarette smokers who inhale. As for nonsmokers who breathe secondhand smoke menthol risk of stroke can be tripled. "Menthol in cigarettes stimulates upper airway cold receptors that can block the breathing mechanism. Not clear why only smoke menthol cigarettes increased risk of stroke and no increased risk of other cardiopulmonary diseases," said Dr. Nicholas Vozoris, one of the researchers from St. Michael's Hospital in Toronto . Research on menthol cigarettes was published on April 9, 2012 in the Archives of Internal Medicine. "These findings mean that smoking is not better than other types of menthol cigarettes.

Roche Develop Breast Cancer Drug Innovation

Yogyakarta , breast cancer is still the highest position as the leading cancer killer of women around the world. However, the treatment given so far is still not optimal in relieving cancer growth. Compared with other countries in Europe and the United States who have cancer incidence rates reaching 70-100 per 100,000 people, the incidence of cancer in Indonesia is still unclear because population-based study to find out it has never been held in Indonesia. But estimated the incidence of cancer in Indonesia is 17-25 per 100,000 people. "Breast cancer alone there are three kinds, the first and most (around 60-70 percent) are caused by hormonal reactions, the latter is the result of the expression of a protein called HER2 cells splitting excess and the third did not get into them. However, the most severe is the result of overexpression of HER2 breast cancer because of more malignant, can develop faster, more prone to metastasis and more resistant to standard drugs, "said ...
