Testosterone protects men from allergies

It was long known that men suffer more rarely from inflammatory diseases than women, but now a new research at  the Institute of Pharmacy of University Jena has found how sexual hormones play an important role in this.
They found that in male cells the enzyme phospholipase D is less active than in the female ones and suggest that testosterone makes men less susceptible to inflammatory diseases and allergies than women.

The Jena pharmacists concluded that the male sex hormones play a key role in the modulation of the immune response. This would also explain another phenomenon that has been previously noticed, that is, testosterone can protect men from arteriosclerosis.
