Investigations in which mice were presented to the SARS coronavirus found that the guys were more helpless to disease than the females, a difference that expanded with age.
The male mice created SARS at lower viral exposures, had a lower insusceptible reaction and were more slow to clear the infection from their bodies. They endured more lung harm, and kicked the bucket at higher rates, said Dr. Stanley Perlman, a teacher of microbiology at the College of Iowa who was the senior creator of the investigation.
At the point when scientists blocked estrogen in the contaminated females or evacuated their ovaries, they were bound to bite the dust, yet blocking testosterone in male mice had no effect, showing that estrogen may assume a defensive job.
