Amino acid good for sex, helps trees too

UMEA, Sweden, Dec. 20 (UPI) -- Swedish researchers have found that an amino acid that aids sexual performance in men also helps spruce trees develop stronger root systems.

A team led by Torgny Nasholm, a forestry professor at the Swedish University of the Agricultural Sciences, created a fertilizer laced with arginine, Vasterbotten-Kurrien reported. The amino acid improves sperm production and blood circulation in the genital area.

Nasholm found that trees given the fertilizer had stronger root systems. As an additional environmental benefit, the trees were able to draw nitrogen more effectively, allowing less nitrogen fertilizer to be used.
