Age is also best avoided as it is the number one cause of bodily deterioration, disease and death.

Comments like this from commenters like this are why I love HN. Does BPA-free plastic improve anything? What about containers of non-prepared food? I can see not eating directly from any, but I think it's pretty hard in the developed world to rid ourselves of plastics entirely in the storage of foodstuffs. Also, do we know whether the changes in sperm quality you mention affect congenital childhood maladies? (I reali…
All plastics are endocrine disruptors [a], though the an easy filter is softer = worse. If anything food related is in contact with plastic there will be plastic in the food. The pH and temperature of the food have a big impact on plastic leaching. And sperm quality mostly affect fertility. The egg and the body if the woman is incredibly effective at selecting quality sperm and rejecting bad sperm. There are multiple…
Am I right?

There is an ongoing discussion on the effect of caffein on sperm quality. There are articles which describes a possible route for DNA damage to the sperm from caffein https://www.cureus.com/articles/109365-effect-of-stress-and-... . From personal (lab) experience there is a clear difference to the smell of sperm from a coffee to a non coffee drinker, so it ends up there somehow. Whether it truly has an effect is stil…
Caffeine has no smell so what you are detecting is some other component or effect on the semen taste. Many things can affect the taste of semen.
My wife and I have a beautiful daughter about to turn 2. But she wouldn't have existed if it weren't for IVF (in vitro fertilization). Had to stab her stomach with needles for a while to make hormones to mass produce eggs and then they took my sperm to put into her eggs and see which ones took. Five viable pairings happened. Three were put into her and out came the one kid. Other two are in cryo for future use, and h…
> and my wife was 38 at the time of conception. This sounds obvious, but apparently isn’t to a lot of younger people. 38 is considered quite old to start having children (yes it happens, but it’s called a “geriatric pregnancy” for a reason), and I’m sure it contributed to the difficulties conceiving. A lot of young folks have been convinced that child birth can be put off more or less indefinitely while you pursue a…
Young folks haven't been convinced of shit, it's just literally not an option. Most young people are barely scraping by, can't buy a home, can't rent a medium sized apartment, have terrible health care, unreliable or unpredictable scheduling, etc etc.
"Oh we made do in earlier times" Yes and a lot of the younger generations feel those scars every day, they feel the anxiety from not having enough money in the household, and develop scarcity mindsets that they will fight for the rest of their lives. Of course they don't want to do that to their own kids.
Let alone even being in a relationship at all, one that's stable enough that you genuinely believe you will be together for at least 20 years.
Young adults aren't putting off kids "to pursue a career", we are trying desperately to survive in a world that was picked clean by previous generations and kneecapped before we got a chance at it.
Several years ago, I switched to products that are EWG verified [1], meaning a product's ingredients are safe for humans. Some of the EWG verified products are quite expensive, so it took a while to find a brand that was affordable and safe to use. I've switched everything to that brand (shampoo, conditioner, soap, dishwasher and laundry detergent, cleaners, ...). They even have a search engine that allows you to sea…
I've switched everything to that brand -- could you share that brand? It would save us a lot of research.
I did my Master Degree in Organic Chemistry where we tried to develop a male contraceptive pill. I spend a lot of time studying sperm so here is a short list of thing to avoid regarding sperm quality (not ranked): 1. Eating and drinking from plastics (This includes aluminum cans which are plastic lined) [a] 2. Heating food in ANY type of plastic [a] 3. Caffein intake [b] 4. Sugar intake [c] 5. NOT exercising regularl…

Years ago, I published a paper suggesting that humans have genomic evidence of strong selection pressure on some sex hormone pathways. So, I am quite curious about whether sperm counts are plummeting solely because of environmental changes (e.g., human created hormone influencing toxins, including "the pill") or also because natural selection in humans has drastically changed with the advent of modern society. In spe…
> “One can view the decline in sperm counts as a biomarker for male health in general,” says Kristensen.
> In fact, a study in a 2018 issue of the journal Andrology found a higher risk of hospitalization among men who had lower sperm concentrations. Those with sperm concentrations below 15 million/mL—considered low—had a 53 percent greater risk of being hospitalized for any reason over the course of 36 years than those with more robust sperm concentrations between 51 and 100 million/mL. This effect persisted even after the researchers controlled for body weight, smoking, and other factors.
Sounds to me like that supports the chemicals theory.

It is interesting, I have a friend group that consists of about 5 married couples all of whom have been having issues conceiving and have been trying for a while now, but are still having issues. Curiously enough my wife and I just had our 4th and every time we've conceived within two months (even when I was hoping it would take a little longer). From what I hear our friends story is not unusual and many in our age b…
I'm a Catholic and fairly traditionally minded and am surprised by what you're saying since at my church, couples in this age range are on their fourth or fifth kid by the time they're 30. Even amongst the newest married couples, most are expecting within the first year. I understand we have different beliefs and such but since we're all in the same environment, how do we explain the simultaneous existence of the see…
