> A recent study found that male infertility rates increased nearly 80% from 1990 to 2019. The reasons driving this trend remain a mystery, but frequently cited culprits include obesity, poor diet and environmental toxins.
> Infectious diseases such as gonorrhea or chlamydia are often overlooked factors that affect fertility in men. Accumulating evidence suggests that a common single-celled parasite called **Toxoplasma gondii** may also be a contributor. An April 2025 study showed for the first time that „human sperm lose their heads upon direct contact“ with the parasite.
> Infected cats defecate Toxoplasma eggs into the litter box, garden or other places in the environment where they can be picked up by humans or other animals. **Water, shellfish and unwashed fruits and vegetables** can also harbor infectious parasite eggs. In addition to eggs, tissue cysts present in the meat of warm-blooded animals can spread toxoplasmosis as well if they are not destroyed by cooking to proper temperature.
> Toxoplasma remains in the body for life as dormant cysts in brain, heart and muscle tissue. These cysts can **reactivate** and cause additional episodes of severe illness that **damage critical organ systems.**
> Between **30% and 50% of the world’s population is permanently infected** with Toxoplasma due to the many ways the parasite can spread.
There is a very poor joke about childless cat ladies here. . . Wait. It’s proof of the joke. Oh my God. Don’t show this to conservatives.
Tinfoil hat time: maybe this parasite co-evolved with cats to reduce the number of offspring the people had so they could devote more resources to their cats.
Here I spent all that money getting a vasectomy and I could have just left it to my parasites. Oh well, hindsight.
I’m infertile because I’m fat and no one wants me, so I guess the obesity link checks out 😆
Babe wake up, new birth control method just dropped
If there’s any truth to this it’s actually disturbing
Seroepidemiology surveys suggested that the consumption of raw cow milk was significantly related to *T. gondii* infection

Wait hol up… but if you’re having sex daily wouldn’t that mean you’re producing new sperm constantly? What the fuck are these parasites doing, throwing a party in my nutsack and sniping every sperm that gets produced? Hmmm the logic doesn’t seem to check out from this study… unless 50% of men are walking around with a sack full of parasites munching on sperm! Lolz
Hmmmm a new reason to share the cat box cleaning duties!
Do you want to have a Children of Men? Because this is how you get a Children of Men
Tldr: cats and parasites working together to not be replaced as the organism that receives the most attention by preventing human baby births from happening in the first place /s
Am I the only one who has basically stopped caring? I mean, it sounds like we’re fucked wherever we look: Microplastics, climate change, forever chemicals, these little parasite bois…
Like bruh, sometimes I wonder, is there’s even a point to push through the Pareto Principle when it comes to a healthy lifestyle?
This basically confirms my conspiracy theory that theres something wrong with fertility worldwide but governments aren’t saying anything to avoid panic. This plus the effects on fertility by long-covid and the increase in obesity and mental health issues paints a very scary picture of a rapidly declining population.
I’m more worried about that shit infecting my brain like in Trainspotting
So can this be harnessed for male birth control similar to how Botox is now used medically
Somehow, it feels just like outside cats with wildlife.
„Whoooops Morty, you might want to go freeze some sperm.“
How is this going to affect the sperm racing community?
Well that’s just great. So now I can’t even feel superior to RFK Jr anymore, because I too have brain parasites? Thanks Reddit.
Nature trying its hardest to tell Kennedy you can’t stop contraceptives. Ban abortion and limit access to birth control? Cool, parasites.

Hm. But why would toxoplasmosis all of a sudden increase after the year 1990?
One of the best ways to avoid this is to keep your cats indoors. Then, they have a far less likely chance of getting this.
Reading this makes me feel like the inside of my skin needs a bath
Undercooked pork is a more likely transmission than cat feces in most places. Transmission from cats is fairly difficult.
Cats ingest an infected rodent and T gondii matures and begins reproducing in the cats intestine. Eventually the cat begins shedding oocysts for 1 to 3 weeks. These oocysts take 48 to 72 hours to become infectious where consuming feces will start an infection in an intermediate host, ie rats, pigs, or humans.
So really have to have the correct sequence of events and timing to contract from a cat, making it unlikely for anyone who doesn’t own a large number of cats or who likes to garden in areas with a high feral cat population.
Whereas in Germany there is a raw pork dish which is likely responsible for the high rate of infection.
