Overindulging in alcohol leads to alcohol-induced erectile dysfunction that may be temporary, in which a person either is unable to get an erection or gets an erection that is weaker than usual.
Alcohol affects sexual activity in the following ways:
Depressed Central Nervous System (CNS)
Alcohol consumption leads to decreased sensitivity of the penis. It affects the transmission between the brain and the penis. A 2018 study confirms that drinking alcohol depresses your neurotransmitters and hormones involved in sex drive.
Alcohol has diuretic effects, which increase the frequency of urination. Frequent urination leads to dehydration and decreased bodily fluids, affecting blood circulation toward sex organs. Dehydration triggers the body’s angiotensin hormone, which decreases blood flow toward the penis, leading to erectile dysfunction.
Decreased sex hormones
Alcohol drinking before sex may alter the level of sex hormones in the body. A study suggests that alcohol consumption leads to decreased levels of testosterone in the body, decreasing the libido in men.
