The Sperm Count Nosedive

Let’s start with some cold, hard facts. Research indicates that sperm production has taken a significant nosedive since the 1900s, putting male fertility and overall health at risk. A meta-analysis conducted by Carlsen et al. in 1992 reported a worldwide decline in sperm counts from 1938 to 1990, based on the semen analyses of nearly 15,000 men from 23 countries.¹

More recent studies have reinforced this alarming trend, with a review suggesting that global sperm counts have plummeted by more than 50% over the past 50 years.² Another study found a staggering 51.6% reduction in average sperm count worldwide between 1973 and 2018, with the decline becoming even steeper after 2000.³

The Testosterone Tumble and Sperm Stress

Now, you might be wondering, “What’s causing this sperm apocalypse?” While there are certainly several complicated factors, there are a few culprits taking center stage: declining testosterone levels and poor sperm quality.

Environmental toxins, lack of exercise and movement, and life stresses are of course playing major roles here, but so are dietary fats. Enter PUFAs, Polyunsaturated Fatty Acids, which have infiltrated modern diets, replacing the good old saturated fats and animal fats that our ancestors thrived on.

The yellow and gray lines (shortening, margarine and vegetable oils) are higher in PUFA relative to the blue and orange lines (animal fats).⁴

And guess what? Your sperm are not fans of this dietary revolution. The reduction in testosterone and sperm quality has correlated strongly with a massive change in dietary fat consumption. We’ve shifted from a diet higher in saturated fat and animal fats to one dominated by PUFAs. This change isn’t just affecting your waistline — it’s messing with reproduction!

while PUFA’s are listed as part of the problem, I think it’s video games, metrosexual trends and interference by females with that male toxicity bullshit that neutered the latest bunch.

Man up out there, stop being pussies.
