What Are Sperm Telling Us?
Something alarming is happening between our legs.
Sperm counts have been dropping; infant boys are developing more genital abnormalities; more girls are experiencing early puberty; and adult women appear to be suffering declining egg quality and more miscarriages.
It’s not just humans. Scientists report genital anomalies in a range of species, including unusually small penises in alligators, otters and minks. In some areas, significant numbers of fish, frogs and turtles have exhibited both male and female organs.
Four years ago, a leading scholar of reproductive health, Shanna H. Swan, calculated that from 1973 to 2011, the sperm count of average men in Western…

Sperm Count Zero
A strange thing has happened to men over the past few decades: We’ve become increasingly infertile, so much so that within a generation we may lose the ability to reproduce entirely. What’s causing this mysterious drop in sperm counts—and is there any way to reverse it before it’s too late?
The rise of Big Sperm: does the tech world have the answer to our semen crisis?
Sperm counts in western men are falling, and nobody is sure why. But relax – because help is here, with everything from home-testing kits to sperm-freezing.
Falling sperm counts 'threaten human survival', expert warns
Epidemiologist Shanna Swan says low counts and changes to sexual development could endanger human species.
Most men in the US and Europe could be infertile by 2060, according to a new study
Overall, this is a very disturbing report. There has been a longstanding debate among scientists as to whether sperm counts have decreased or not. But what’s different about this study is the quality of the analysis.
Sperm counts are falling. This isn’t the reproductive apocalypse — yet.
Seven questions about declining sperm counts you were too afraid to ask.
The Dawning of Sperm Awareness
Men are embracing sperm health, while society is recognizing that fertility isn’t just about women.

Sperm: why these secretive swimmers are the key to the future of fertility – and contraception
Despite the huge global demand for both fertility treatment and contraception, there are surprisingly few options to boost male fertility, or for male contraception. To have more options, we really need a better understanding of how human sperm work. Unfortunately, they are incredibly difficult to study in the lab. Not only are sperm the smallest cells in the body (25 times smaller than a grain of sand), they are unique and highly specialised, designed to survive outside the body.
A Smartphone Can Accurately Test Sperm Count
Men may soon be able to take their own sperm count — at home. With a smartphone. Yes, there's an app for that. You may be asking yourself, why?
Are Your Sperm in Trouble?
As a couple finishes its business, millions of sperm begin theirs: rushing toward an egg to fertilize it. But these days, scientists say, an increasing proportion of sperm — now about 90 percent in a typical young man — are misshapen, sometimes with two heads or two tails.

Boxers Or Briefs? Experts Disagree Over Tight Underwear's Effect On Male Fertility
If you've ever seen someone with testicles get kicked in the groin, then you probably know that male genitals — often portrayed as a symbol of male strength and virility — aren't actually that tough. But can testicles — or rather, the sperm they produce — be harmed by something as seemingly innocent as a pair of briefs?
Climate change: effect on sperm could hold key to species extinction
Currently, we have a disturbingly limited knowledge of which biological traits are sensitive to climate change and therefore responsible for local extinctions. However, a potential candidate is male reproduction, because a range of medical and agricultural studies in warm blooded animals have shown that male infertility happens during heat stress.

Sperm Counts Continue to Fall
Scientists are coming to a consensus that men in America and Europe are experiencing a worsening decrease in fertility. They disagree, however, about why.
These new sperm tests could be a fertility breakthrough
The Seed test, like others now in development, will help a man understand why he's infertile even if his sperm looks normal under a microscope. But while doctors may advise those men to lose weight or stop smoking in an effort to improve their epigenetic profile, there's no treatment yet. That means, often, the test results will be most useful in driving home that the infertility is real.
Unhealthy sperm can play a role in lost pregnancies
Bringing a pregnancy to term requires a healthy sperm and egg.
