Scientists discover key ingredient in sexual reproduction

to treat male infertility.

For example, in the process known as in vitro fertilization, egg cells are taken from a woman and fertilized with sperm in a laboratory test tube. By adding nitric oxide to the mix, men with nitric oxide deficiency might one day be able to use their own sperm in the process instead of relying on a sperm donor.

Just say NO

Often confused with nitrous oxide, or 'laughing gas', nitric oxide (NO) is a simpler compound consisting of a single atom of nitrogen (N) bound to a single atom of oxygen (O).

Long dismissed as a toxic air pollutant, NO has won tremendous respect in recent years, as medical researchers learn more about the important role it plays in human physiology. Nitric oxide maintains blood pressure and flow by keeping our blood vessels open - a significant discovery for cardiologists as well as for the manufacturers of the impotence drug, Viagra. NO also functions as an important neurotransmitter in people and is used by white blood cells to kill tumors, bacteria and other invaders.

Based on the latest findings in Nature, this simple but essential gas may turn out to hold the key to successful fertilization in human beings and throughout the animal kingdom.
