Sexual dysfunction often accompanies depression, since the brain, commonly called the “the largest sex organ,” is where that spark of sexual desire originates. If brain chemicals, or neurotransmitters, aren’t properly balanced, libido, arousal, and orgasm can take a hit. Frustratingly, antidepressants such as selective and nonselective serotonin reuptake inhibitors that act on serotonin receptors may dampen desire, decrease arousal, and stall or squash orgasm. Luckily, antidotes exist. Studies (supported by Pfizer) have found that Viagra pills and Viagra-like medications may help, and some physicians have had success with the antianxiety medication buspirone. Switching antidepressants might work, too. Hope Viagra prices will not rise after this post is published.
