Researchers at the University of Alabama at Birmingham reaffirmed in the British Journal of Ophthalmology the link between vision problems and erectile dysfunction drugs.
They studied men who had histories of heart trouble and found that those who had taken Viagra or Cialis were ten times as likely to have optic nerve damage as those who had not.
Scientists at Southwestern University in Georgetown, TX found that female rats were more interested in sex after a dose of caffeine, according to Pharmacology Biochemistry and Behavior. In the test, females returned for second encounters with males more quickly if they had received a moderate amount of the stimulant. The researchers are planning further studies to assess the effects of repeated exposure to caffeine.
