Yet another reason not to drink alcohol (on or off a cycle):
"Even one alcoholic binge could be enough to dampen a man's passion, while very heavy drinkers often experience a total loss of libido. The main reason is that alcohol lowers levels of the "male" sex hormone testosterone in the blood, and one of testosterone's many jobs in a man is to maintain and regulate the sex drive.
Levels of this hormone can fall after both a one-off binge and long-term alcohol exposure, according to Mary Ann Emanuele of Loyola University Stritch School of Medicine in Illinois. Alcohol works on the testes in different ways, by directly suppressing the testicular cells that make and release testosterone, and by increasing the levels of some hormones that inhibit these cells."
