>Over the 26 years of the study, they found a striking decrease in the percentage of normal motile sperm. Between 1988 and 1998, sperm motility declined by 2.5 per cent per year and following a short period when stud dogs of compromised fertility were retired from the study, sperm motility from 2002 to 2014 continued to decline at a rate of 1.2% per year.
>In addition, the team discovered that the male pups generated from the stud dogs with declining semen quality, had an increased incidence of cryptorchidism, a condition in which the testes of pups fail to correctly descend into the scrotum.
>Sperm collected from the same breeding population of dogs, and testes recovered from dogs undergoing routine castration, were found to contain environmental contaminants at concentrations able to disrupt sperm motility and viability when tested.

More like mammals
Its the estrogens in the water man. Not tinfoil look it up
It happening to you, too
>>65752
dog population control...
like the zika virus...population control
>>65908
I'm not averse to people like you getting sterilized.
>>65752
This is being done intentionally.
Makes sense, just the other day my dog was asking me to take him to the groomers to get a trendy haircut. Then he let a chocolate lab mount his gf.
Nu dogs confirmed.

Definitely nothing to do with the centuries of inbreeding required to create the genetic freaks we refer to today as "dog breeds"
>>65914
A true top shelf kek
>>65752
I wish this would happen to humans.
>>65894
If I'd been castrated at a young age I think I'd be a lot happier now
>>67917
Have you seen Children of Men?
>>67917
You should say third world humans.

Holy kek.
>>67917
Isn't it? I remember hearing sperm counts were consistently decreasing across first world countries. I'm sure it's something to do with plastics and chemicals with estrogenic properties. That or growth hormones in food.
>>65914
I hope you get sterilised
>>65752
Yes good goy, spray more fertilizers and pesticides on your lawn.
>>67935
I have. I didn't say I want total infertility.
But if it was maybe a lot harder, but still possible to procreate, that might be the sweet spot.

>>67917
But it is. We might die out before we go explore space
So who is picking which breeds to get rid of? Food?
Why is everybody referencing Children of Men all of a sudden?
is that the new high school reading or something?
>>68314
feels great to be third world, brah
>>65752
Oh boy big shock, selectively breeding for physical traits with little to no mind paid to genetic risk factors and bad traits has resulted finally in impotency.

Just a thought. The pill is not completely water soluble and in heavily populated areas (e.g. London) the water is filtered a fuck ton.
> Tablet components remain in water
> Water given to dogs
> Dogs semen quality decreases
