Have men jerked themselves into infertility?

What? I’ll have to look into that! Zinc and copper depletion??? Oh my…

Ok so this is what I found:

www.frontiersin.org

This study aimed to investigate the situations of pornography use among male college students of China, to explore the addiction possibility for pornography use, and to study the associations between pornography use and reproductive hormone levels and semen quality. Five hundred sixty-eight participants met the inclusion criteria and finished all of the questionnaires and hormone level and semen parameter examinations. A majority of participants (except one) had pornography use experience, 94.2% participants started pornography use before college, and 95.9% participants reported they had masturbation experience when using pornography. Early contact to pornography, frequent pornography use, high amount of time spending on pornography use, and frequent masturbation during pornography use were correlated with addiction trends. Earlier pornography use was found to be associated with lower serum prolactin (PRL), follicle-stimulating hormone (FSH), and progesterone (Prog), as well as lower sperm concentration and total sperm count. Higher frequency of pornography use was associated with lower serum estrogen (E2). In conclusion, pornography use was common among male college students in China. Early contact, high frequent use, and high frequency of masturbation during pornography use could lead to addiction trends and aberrant reproductive hormone levels and semen quality.

Yup....

"students with higher pornography use frequency had lower E2 concentration in serum...

...earlier pornography use, higher-frequency exposure to pornography, higher-frequency of masturbation when using pornography were associated with lower sperm concentration and total sperm count (p < 0.05).

6.5% of students thought it would be easier to achieve sexual satisfaction when using pornography than with a real sexual partner...

As we discussed in the previous section, adolescence is a key time for reproductive maturation, from sexual hormone secretion to sexual organ development. The time of puberty initiation and the time for first sexual encounter were found to be two developmental milestones associated with reproductive maturation (38). Earlier contact to pornography might lead to disturbance of sexual hormone secretion, and therefor lead to lower sperm concentration in adult semen."

Thank you for finding this! someone @ National Geographic with this lol

We did-perhaps this is Mother Nature's way of pulling the plug on us!

That sounds right to me, also there's the factor of Millennials being much more overworked than their parents and having much lower paying jobs when adjusted for inflation with fewer benefits. More work = more stress = more health issues.

Plus global warming and nutty, fascist, or plain incompetent government looming over it all...even more stress!

Side note: love your username hahaha.

It's legit almost comical how porn consumption doesn't even get a side note here. How has no one though to look at that as a potential cause?

Tbh I think you two are onto something, because a lot of medicine (both clinically and research-wise) tends to be quite patriarchal. Medication dosages, research participants, even the default pronouns of hypothetical medical doctors or surgeons, often favour men.
