The chemicals in Sunscreen Can interfere with the function of Sperm

The chemicals in Sunscreen Can interfere with the function of Sperm - Some of the chemicals contained in products of sunscreen, it can interfere with the function of sperm cells. Some of which mimic the effects of the female hormone progesterone, says a recent study in Denmark.

"The results of this study to the attention of many people and explains partly why cause factor of infertility in men is increasing lately," said the study's senior researcher, Niels Skakkebaek, MD, DMSc, a professor at the University of Copenhagen and researcher at Copenhagen University Hospital, Rigshospitalet.

Even though sunscreen works to reduce the amount of UV rays of the Sun penetrate the skin allow it in a way we are, in fact it is precisely some of the chemicals in sunscreen lotions can absorb into the skin and gives a negative effect, said Skakkebaek.

Sunscreen chemicals found in the human blood sample and a urine sample at the 95 per cent of men in the u.s., Denmark and other countries.

Skakkebaek and his colleagues tested 29 of 31 products sunscreen in the u.s. and the European Union, as well as researching healthy human sperm cells obtained from several donors. Sperm cells undergo testing in buffers that resemble conditionsin the tuba.

Specifically, researchers are evaluating the calcium signal, which appears in the cells caused by changes in the concentration of calcium ions. Movement of calcium ions in the sperm cells play a major role in the function of sperm cells, according to Skakkebaek.

CatSper ion channel is the sperm calcium is very important for the fertility of the man. This channel is the main receptor of sperm for progesterone, a atraktan (towing) powerful hormones for human sperm cells.

Progesterone binding with calcium ions cause CatSper entered into sperm cells for a while, control multiple functions of sperm required for fertilization.

The researchers found that 13 fruit products, or 45 percent, of 29 products sunscreen can disrupt normal sperm cell functions.

"This effect is already started on a low dose (of chemicals contained in products), below the level that is commonly found in people who wear sunscreen to all parts of his body," said Skakkebaek.

Furthermore, nine of the 13 products, seems to induce calcium ions by means of CatSper channels enable, and thus meaning that mimic the effects of progesterone. In short, the sunscreens are screwing up the sperm motility and endocrine, Skakkebaek said.

Skakkebaek advocated further clinical studies to investigate whether sunscreen products affects the fertility of women as well. "Our Study also urged, in order that the Government examine again the effect of sunscreen against fertility before giving permission to trade."
