A study suggests that men who drink tea may have a better chance of conceiving.
Researchers in China studied the sperm quality of nearly 1,400 men.
Their results showed that Kappa Semi males had higher sperm concentration and mass.
The sperm-enhancing benefits were only seen in men who drank tea three days a week, so experts don’t know if drinking a cup every day is better.
Researchers at Hubei University, the city where Covid originated, concluded that ‘drinking tea improves men’s reproductive health’.
Sperm numbers have been declining over the past few decades, prompting warnings of a male fertility crisis.

Researchers in China who studied the sperm quality of nearly 1,400 men found that tea drinkers had higher sperm count and sperm count. Pictured: A sperm approaching an egg.
What is a low sperm count?
A low sperm count is when a man has less than 15 million or 39 million sperm per milliliter of semen.
Although a successful pregnancy can still occur, it makes it more difficult to conceive naturally.
Sperm problems, including low sperm count and sperm quality problems, affect one in three couples who struggle to conceive.
If men are unable to conceive after a year of trying, they are advised to contact their doctor who can arrange a sperm analysis.
This includes testing the quality and quantity of sperm.
Victims may be advised to continue trying, undergo IVF, use donor sperm or hormone therapy to increase sperm count.
Low sperm count can be caused by hormonal imbalances, genetic problems, undescended testicles, or genital infections.
Excessive alcohol consumption, smoking, and use of drugs such as marijuana and cocaine are known to worsen the condition.
Being fat affects sperm quality, say doctors.
That’s why men who want to be fathers remember the benefits of eating a balanced diet and exercising regularly.
Certain healthy foods, such as fruit, green leafy vegetables and beans, have been independently linked to better sperm concentration and motility – the ability to move more efficiently.
Similarly, fertility studies have suggested that red meat, coffee and sugary snacks can lower sperm quality.
But the experts behind the latest project say that the effect of drinking tea on sperm is not clear.
Between April 2017 and July 2018, they recruited 1,385 people who provided four samples each.
Volunteers were also asked about their health and lifestyle.
All participants were healthy and were being investigated as potential sperm donors by the Human Sperm Bank of Hubei Province, China.
The results were published in a scientific journal Chemosphere28 percent drink tea, 72 percent don’t.
The volunteers did not say what kind of tea they drank, whether they had added milk or sugar.
But it was practiced in China, where green, oolong, and black teas were prevalent—and often combined with water.
Compared to non-tea drinkers, cup drinkers had higher sperm count — the number of sperm per milliliter — and sperm count, which is the total number of sperm per ejaculate.
Low sperm count is less than 15 million per milliliter of semen, and low sperm count is less than 39 million per milliliter.
The researchers found that men who drank tea at least three days a week had five percent higher sperm count and 0.4 percent higher concentration.
However, those who drank tea less than three days a week did not see the same benefits—in sperm count and concentration—as non-tea drinkers.
The team found that those who drank tea for 10 years or more had 15.3 percent higher sperm count than those who did not drink tea.
However, there was no relationship between tea consumption and sperm motility and structure – two other factors that can affect male fertility.
The researchers, led by Xia-ren Liu, concluded, “Our findings provide evidence that drinking tea can improve male reproductive health.”
The benefits of drinking tea may be down to the polyphenols – compounds in the drink that are packed with antioxidants and are known to boost sperm survival.
A low sperm count or concentration can make it difficult for a man to conceive naturally – a problem that affects a third of couples who struggle to conceive.
If men are unable to conceive after a year of trying, they can have their sperm tested by their doctor.
There are also home tests available at pharmacies and online. But doctors caution that these are understudied and not very thorough.
Studies have shown that sperm count has plummeted, prompting fertility experts to fear that the situation ‘endangers human survival’.
Dr. Shana Swann, an epidemiologist at the Icahn School of Medicine at Mount Sinai in New York City, produced a groundbreaking 2017 study that found that sperm count has more than halved worldwide over the past four decades.
She warned that chemicals such as phthalates in toiletries, food packaging and children’s toys are to blame everywhere. The chemicals cause hormonal imbalances that can cause ‘reproductive harm’, she said.
Factors including tobacco and marijuana smoking and increased obesity may play a role, Dr. Swan said.
