Does coffee raise testosterone level?

Coffee was once considered a drink that does more harm than good. Today, however, we know that its consumption is not harmful, and moderate coffee consumption brings many benefits to the entire body.

Epidemiologists working at Harvard University set out to study the effect of coffee on the levels of estrogen and testosterone in the body of both women and men. They published their research in the American Journal of Clinical Nutrition. This is an interesting issue for people who doubt the health-promoting effect of coffee.


The researchers analyzed data from 17,881 women and 8,848 men. They were health workers, mostly nurses. The subject of the study was the amount of consumed coffee with and without caffeine.


As a result of the hormonal blood analysis, scientists found a greater amount of testosterone and a smaller amount of estradiol in people who drink at least 1 cup of coffee a day. It should be noted that these differences were statistically significant, which makes the study more meaningful.

People who drank 4 cups of coffee a day or more had an additional amount of adiponectin in their blood – a hormone responsible for insulin sensitivity, anti-inflammatory and anti-atherosclerotic effects. Additionally, a lower amount of the pro-inflammatory factor CRP was noted in those people.


Scientists agreed that coffee consumption was associated with an improvement in hormonal balance. Drinking coffee has a significant impact on metabolic health as well as the functioning of the endocrine system.
