10 分钟Hey listeners, Rachel here.
It's been a year since I started hosting Science Quickly,
and because of that, I have a quick favor to ask.
We would love to get your feedback on how Science Quickly has been doing and how you might like to see us evolve.
That's why we're putting out a listener survey.
If you complete it this month, you'll be eligible to win some awesome Scientific American swag.
You can find the survey at sciencequickly.com slash survey,
or we'll also have that link in our show notes.
It would mean a lot to us if you took a few minutes to complete the survey.
We promise it won't take too much of your time.
Again, you can find the survey at sciencequickly.com.
Thanks in advance for letting us know your thoughts.
For Scientific American Science Quickly, I'm Rachel Feltman.
The World Health Organization estimates that infertility impacts one in six adults globally.
But when it comes to addressing infertility, male partners are often left out of the equation.
Some studies suggest that in 18 to 27 percent of cases where a heterosexual couple seeks medical help for fertility issues,
doctors won't bother to run any tests on the man.
Those stats might make you think male fertility issues are rare, but that's definitely not the case.
According to some estimates,
male fertility issues are the sole cause of infertility in some 20% of cases and contribute to the problem in another 30 to 40% of cases.
