According to Dr Laura, almost 40 per cent of all infertility cases are due to male-related issues and low sperm count
is the number one reason for male infertility.
The sperm counts
of those who ate pizzas, burgers and chips were 26 million lower than those on a "healthy" diet of fish, chicken, vegetables, fruit and water.
Speaking about it, lead author Dr Kristina Weibring said, aACoeWe wanted to examine in more detail if postoperative treatment, given to decrease the risk of recurrence after the removal of the tumorous testicle, would affect the sperm count
and sperm concentration long term in testicular cancer patients with no spread of the disease.
The result came as a surprise to Harvard University scientists measuring the sperm counts
of more than 600 men from couples attending a fertility clinic.
Instead, those participants who admitted ever taking the drug turned out to have higher sperm counts
He said: "Sperm counts
are declining at such a rapid rate it isn't just to do with genetics.
"Our study clearly shows that low sperm count
by itself is associated with metabolic alterations, cardiovascular risk, and low bone mass," Ferlin said in a statement.
RESEARCHERS are warning men's sperm counts
are falling at such rates that humans could fall under threat of extinction in the future.
Furthermore, recent studies have also linked lower sperm counts
with male health problems, including a number of illnesses and even premature death.
There have been many estimates of what is happening to sperm counts
, but they are conducted under different circumstances, usually with fairly small groups of people, and often in clinics that are treating couples with infertility problems.
Dr Hagai Levine, of the Hebrew University of Jerusalem, who co-led the research, said: "Given the importance of sperm counts
for male fertility and human health, this study is an urgent wake-up call for researchers and health authorities around the world to investigate the causes of the sharp ongoing drop in sperm count
, with the goal of prevention."
The study found a 52.4% decline in sperm concentration, and a 59.3% decline in total sperm count
in men from North America, Europe, Australia and New Zealand.
