But we know it's not true anymore.
It's 50-50 for men and women.
Yeah, two major international studies were published.
In the first study, they showed that overall sperm count was 60% decline.
And in the follow-up study, they showed that there was a decline of about 2.6% per year in sperm count.
And that's a drastic drop.
Subsequent studies have shown that there was an increase in sperm count.
So what it demonstrates is that regionally, there is a decline in sperm count, but universally, it may not be as drastic as you think.
The studies attributed that to the Western diet and also an increase in environmental toxicants, chemicals, in particular endocrine disrupting chemicals, which can mimic hormones and as a result disrupt the normal hormonal signaling that makes sperm.
They're everywhere.
They're usually used in plastics, in fire detergent or retardants.
Yeah, the forever chemicals, yeah.
And we live in a soup, we're surrounded by these chemicals.
Now, there's a close association, but a causative link is something that has to be determined yet.
There are causes that we know
do result in post-sperm quality.
Smoking is one of them, and that can damage sperm.
Vaping is not the healthy alternative.
There's evidence to suggest that it can impact testicular health as well.
Really?
