Libido, or sexual desire and arousal, is a symphony of biochemical signals:

• DHEA (see Tip 46):  In animals, DHEA promotes libido, orgasms, and sex appeal.

• Dopamine:  A neurotransmitter, it is a primary brain chemical responsible for desire and arousal.  By prompting the release of Lutenizing Hormone Release Hormone, dopamine causes men to produce testosterone.

• Testosterone: The key hormone necessary for sexual desire in both men and women, and is critical for men to achieve erection.

• Oxytocin:  A protein produced in the brain, it reaches peak levels during orgasm.

After ruling out other possible causes of decreased sexual desire, a qualified physician can identify whether biochemical imbalances play a contributing role
