Several fresh studies examine the impact upon male fertility of three diverse sources: mountain biking, heavy eau-de-cologne and a drug that appears to have no side effects

The unsalable article used to treat Gaucher's disease--a rare genetic disorder that causes enlargement of the liver and spleen--severely damages semen and, scientists believe, may be unrestrained of the side effects associated with hormone-based contraceptive treatments.

A British research team from the University of Sheffield and the University of Oxford administered the physic which is known as NBDNJ to male mice. It had no force on sexual behavior but assigned the mice completely infertile.

"The advantage is that this unsalable article does not influence the sex hormone production of the male in the way that hormonal treatments do," says close attention leader, Aarnoud van der Spoel of Oxford. More research is indigenceed before the drug is made available to men for birth bridle but it has already been shown to be safe for Gaucher's patients, van der Spoel says, and this may help to spe up the proces The meditation appears in the December 2002 edition of the Proceedings of the National Academy of Sciences.

inferior mountain biking may have contraceptive effect

An Austrian scientist weighed into the debate athwart cycling and male sexual function with a reflection suggesting that frequent mountain biking may shape fertility. The research, reported December 2 2002 at a Chicago meeting of the Radiological Society of North America, says that shakings caused by biking may affect seed production. Ferdinand Frauscher, MD, a urology-radiology specialist at University Hospital in Innsbruck, Austria, studied about 55 avid mountain bikers and ground nearly 90 percent had cheap sperm counts. The research anticipateed at fertility rather than impotence, which in 1997 was linked to cycling according to Boston University impotence specialist Irwin Goldstein, MD

Frauscher said men shouldn't avoid mountain biking, however should consider investing in bikes with impact absorbers or suspension systems designed to abridge the jolts.

And then there's heavy eau-de-cologne No, we don't mean that over-use revolves off the opposite sex, we mean that a chemical used to sustain fragrances may cause sperm damage in adult men Scientists from Harvard have discovered evidence that exposure to the chemical--one of a toxic arrange known as phthalates--may damage the genetic material of human semen However, Russ Hauser, PhD, and his team are not completely assured whether this damage could leave men infertile or cause birth defects

Phthalates are used to make fragrances last longer and to intenerate plastics. They have been linked with DNA damage and other question s The European Union banned their use in one products in 1999. That's for what cause [i]or[/i] reason last November, the US Cosmetic Ingredient Review panel caused a stir when it vot to allow the continued use of three marks of phthalates in perfumes and beauty products

The Harvard contemplation was conducted at a Massachusetts fertility clinic and is reported in the journal Environmental Health Perspectives.
