British researchers claim that drinking coffee in large quantities is fraught with a decrease in reproductive ability in men.
Scientists conducted a study with the participation of 2.5 thousand male volunteers who consumed various types of coffee-containing drinks and coffee.
The researchers studied the semen samples of the participants in the experiment, and found that coffee significantly reduces the amount of sperm contained in semen.
So in men who often consumed coffee drinks, 2-3 cups per day, sperm fertility was reduced to 35 million sperm per 1 milliliter.
And the sperm of non-coffee enthusiasts contained 50 million active sperm per ml.
Experts noted that coffee lovers are often workaholics, which also has a negative effect on reproduction..
