Male sperm count has fallen by more than 50% globally in the last 50
years, leaving researchers scrambling to understand why. Could it be
pollution, PFAS and other potential toxins in our food and water, an
increase in obesity and chronic disease, or even the ever-present mobile
phone?

A new study explored the role of cell phones and found men between the
ages of 18 and 22 who said they used their phones more than 20 times a
day had a 21% higher risk for a low overall sperm count. The men also
had a 30% higher risk for a low sperm concentration, a less important
measure of sperm count in a milliliter of semen. The study did not
specify whether the men called or texted or used their phones to do
both.

On the positive side, researchers found that as phone technology
improved over the 13 years of the study, the impact on sperm count began
to ease.

�I am intrigued by the observation that the biggest effect was
apparently seen with older 2G and 3G phones compared to modern 4G and 5G
versions. This is not something I am able to explain,� said Allan Pacey,
deputy vice president and deputy dean of the faculty of biology,
medicine and health at the University of Manchester in the United
Kingdom, in a statement. He was not involved in the study.

Another plus: There was no decline in the shape and motility of the
sperm, which refers to the way sperm swim to their destination,
according to the study.

�Whilst sperm numbers matter, the ability of sperm to swim, have healthy
intact DNA and be the right shape, is at least as important,� said
Alison Campbell, chief scientific officer of Care Fertility, a network
of fertility clinics, in a statement.

�This is a fascinating and novel study which should not cause alarm or
drastic changes in habits,� said Campbell, who was not involved in the
study. �Men looking to conceive, or wanting to improve their sperm
health should exercise (but not overheat in their groin area), eat a
balanced diet, maintain a healthy weight, avoid smoking and limit
alcohol and seek help if they are having problems conceiving.�

An electronic field
Mobile phones have become indispensable parts of our lives. However,
cell phones do emit low-level radiofrequency electromagnetic fields, or
RF-EMF. If those cell phones are emitting at maximum power, the study
said, surrounding tissue can be heated up to 0.5 degrees Celsius or
about 33 degrees Fahrenheit.

�Cell phones are constantly sending and receiving signals and they are
going to receive and send more intense signals when they�re in use,�
said Dr. Alexander Pastuszak, an assistant professor of surgery and
urology at The University of Utah School of Medicine in Salt Lake City.

�But especially with the modern cell phone, like that signal is going to
vary depending on whether you�re talking or whether you�re sending data,
said Pastuszak, who was not involved in the study.

Radiofrequency electromagnetic fields are greatly reduced when texting
and highest when downloading large files, streaming audio or video, when
only one or two bars are displayed, and when in a fast-moving bus, car
or train, according to the California Department of Public Health.

The agency recommends keeping the phone away from the body and head �
use the speakerphone or headphones instead � and carry the phone in a
backpack in a backpack, briefcase or purse.

Whether those fields can actually damage male fertility, however, has
been a source of controversy and debate for years in the scientific
community.

Studies in mice have found RF-EMF fields at levels similar to cell
phones do lower male fertility and contribute to sperm death and changes
in the tissue of the testes. However, other animal studies have not
replicated those effects, and there are huge differences between humans
and mice in how sperm are created.

Observational studies in humans have also found that frequent use of
mobile phones was connected to a decline in sperm viability as well as
an impact on how the sperm swam. But those studies have been small and
short. And they didn�t necessarily control for factors such as smoking
and alcohol consumption, leaving many scientists unimpressed.

�I have been asked many times over the past decade whether there is any
link between mobile phones and male fertility. However, I have been
largely unconvinced by the data which has been published to date,� Pacey
said.

�However, (this) study is a little step forward in the debate because
this is a large epidemiological study which appears to have been very
well conducted,� he said. �It is a study in the real world � and that is
good in my opinion. However, we should be cautious about its
interpretation as it only shows an association between mobile phone use
and semen quality.�

Young military men
Men could choose whether they carried their cell phone in a trouser
pocket, breast pocket, belt carrier or elsewhere, but over 85% of them
placed their phones in their pants pocket when not in use.

Results showed that men who used their phones one to five times a day or
less than once a week had much higher sperm counts and concentration. As
cell phone usage climbed, sperm count dropped, with the lowest levels
among men using their phone 20 or more times a day.

Researchers also evaluated the impact of cell phones over different
periods of time. The greatest association between low sperm count and
concentration and phone use were between 2005 and 2007. As companies
moved from 2G up to 5G, the association weakened, in line with the
�corresponding decrease in the phone�s output power,� the study said.

�It�s very, very difficult to draw a definitive conclusion from this
type of study because it�s not controlled well enough to be able to do
that,� Pastuszak said. �They can�t control for the day-to-day exposures
of living in an urban environment, and those should not be understated.
Even stress levels can impact spermatogenesis and hormone production.�

As an infertility expert who works daily with couples trying to
conceive, Pastuszak points to the fascinating complexity of factors that
impact infertility, for which sperm count and concentration are minor
players.

�Total sperm count may not reflect actual decreases in fertility
potential,� he said. �I can�t look a patient in the eye and say, just
because you have 100 million sperm per milliliter with 50% motility and
a sperm count of 500 million, that you�re going to be fertile,� he said.

�It�s the quality of sperm that counts. If you have quality sperm there
is a good, decent or even great chance that you can have a child, even
if you have just a literal handful of sperm.�
