Beef Cause Less Fertile Sperm

Eating meat is not always good for health. In addition to triggering cholesterol, meat was also disrupt the continuity of reproduction. Recent studies of scientists United States (U.S.) says that beef potentially damage human sperm.

Scientists from the University of Rochester said that pregnant women who eat too much beef risk of having a baby boy with low sperm quality. The definition of low is less fertile.

Not beef it is a trigger, but the chemical content contained there. The content of chemical substances that are triggering the growth that is already banned in Europe since 1988 ago. In 1979, the U.S. also had to ban the use of hormones testosterone and progesterone in cows. But the fact is still widespread use in the meat industry.

Rochester scientists are testing sperm count among U.S. men born between 1949 and 1983. Mother of the men who ate more than seven times that of beef per week to produce children who have sperm quality workers.

Their sperm concentration is only 43.1 million sperm per millimeter in seminal fluid. The mothers who ate less beef delivery boy with a sperm concentration of more dense, 56.9 million sperm per millimeter.

Infertile Caused By Beef

Mothers who ate more beef producing sons with 17.7 percent of sperm quality standards established under the World Health Organization. According to WHO, the level of sperm concentration of 20 million sperm per milliliter is considered infertile.

Professor Shanna Swan, head of the study say that the most blame in this case is the use of the content contained on the trigger growth of beef. Swan admitted he had not yet had a chemical-specific data content of what is found in beef, but it is definitely not a pesticide or lifestyle factors.

"In theory, fetuses and small children are very sensitive to steorid sex. We are very concern about the consumption of residues of steroids in meat by pregnant women and small children, "said Swan, told BBC News.

Study material exposures trigger role in the growth of beef was repeated at the European men who were born after 1988.

Meanwhile, Dr Allan Pacey, senior lecturer in andrology from the University of Sheffield, said although he has yet to produce sperm until puberty, testicular organs they've developed to prepare produce sperm. The scientists also had time to analyze the impact of estrogen use of chemicals contained in water, plastic or cosmetic ingredients. These chemicals can affect the critical stages of testicular development sons.
