Coffee is the drink that most of us love However, excessive consumption of coffee can cause some changes in the human body.

Similarly, the testosterone level can also be changed by coffee. Do you know what impacts coffee has on the testosterone level of your body? 

It is no surprise that a study has shown that there is an increase in testosterone due to excessive coffee intake.

The primary sex hormone in the body of males is testosterone. It plays a vital role in men’s bodies as it helps them develop a healthy reproductive system (along with secondary sexual characteristics) when they grow up. Coffee increases its level in males.

Coffee does not kill testosterone. In fact, drinking coffee regularly can result in an increase in testosterone hormones in the body. This is because coffee contains an aromatase inhibitor that boosts testosterone production. Overall, coffee is recommended for those with low testosterone levels.

Moreover, males usually have more testosterone levels in the morning than the rest of the day. If they consume coffee in the morning, the caffeine will increase testosterone even more. 

Furthermore, this hormone is assumed to be in a naturally increased amount. However, some males do not have the same testosterone level in their bodies compared to other men.

Suppose a man’s testosterone level is lower than needed. In that case, he can consume more caffeinated coffee to increase it when needed.

Caffeinated coffee has been shown to increase testosterone by 21%, but decaf coffee seemed to have no effects whatsoever on testosterone.

Research showed that coffee could not lower the testosterone level. This experimental research concluded that the only impact of coffee on testosterone level was observed when caffeinated coffee was consumed.

Can I Drink Coffee Before a Testosterone Test?

You shouldn’t drink coffee before a testosterone test. Health experts advised against drinking anything but water before a testosterone test, especially coffee since caffeine can mess with the results of your test.

A testosterone test is simply a blood test to analyze the testosterone level in one’s body. This test is taken to see the “natural amount of testosterone your body normally secretes.” 

If coffee is taken before this test, your testosterone will increase. Consequently, the test will show an amount of testosterone that you do not naturally possess.

Moreover, experts suggest that you must not take anything before the testosterone test except water. Food can affect your testosterone level. For example, sugar decreases testosterone levels. Only water should be taken before the testosterone test to get the most accurate results.

Hence, you must not consume coffee before a testosterone test. It is not recommended at all. 

Best time for testosterone test: Fasting is suggested before this test. An average person cannot stay hungry for hours without feeling dizzy and weak. Hence, one should get tested in the morning. At this time, everyone wakes up hungry and can quickly go for tests to get the most accurate results. The time between 7 AM-10 AM is the best for this test.
