Alcohol and Male Sexual Function

If a man drinks excessive amounts of alcohol, he can develop a number of sexual problems, including erectile dysfunction and delayed ejaculation.

Having a few drinks might help you relax, but too much drinking, especially over time, can ruin your sex life.  Alcohol is a depressant that affects your central nervous system.  This system is necessary for proper sexual functioning. 

Here are some sexual problems that result from too much alcohol:

Erection problems.  Blood flow to the penis is essential for getting a good erection.  But alcohol can damage the blood vessels to your penis and make erections difficult.

Ejaculatory problems.  Many men who drink too much develop delayed ejaculation.  This means it takes them 30 minutes or more to ejaculate, no matter how aroused and stimulated they are.  Some men can’t ejaculate at all.

Low testosterone/hypogonadism.  Drinking too much alcohol can cause testosterone levels to drop.  Low testosterone often leads to diminished sex drive and erectile dysfunction. 

Risky behaviors.  When people drink alcohol, they’re more likely to engage in risky behaviors, like unsafe sex.  With this comes a host of potential issues, like sexually transmitted diseases (STDs) and unwanted pregnancies.  Affairs are another common consequence, leading to relationship issues that can worsen sexual relations with a committed partner.

The bottom line: be careful when you’re drinking.  And if you think you have a drinking problem, be sure to get help.
