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.

So drinking containers should generally be ceramic, glass, or stainless steel?

I might as well stop using condoms.

Switch to PS5 + Mountain Dew. 30 minutes before sex, microwave a cookie in tupperware and drink a beer. For added protection, download the critically acclaimed MMORPG Final Fantasy XIV. With an expanded free trial which you can play through the entirety of A Realm Reborn and the award winning Heavensward expansion up to level 60 for free with no restrictions on playtime.

I've never written about this before but thought it might be useful for someone who may be experiencing the same/similar problem and believes there's no real prospect of having children. During several years of trying to conceive, I undertook 2 sperm tests with the clinic and on both occasions drew a blank - literally nothing. I can't describe how brutally crushing this is to receive as news - especially from a poorl…

"Hey honey I found out about this new procedure called microdissection testicular sperm extraction..."

"I'm going to have to stop you right there"

I'm just kidding around, but that could really use a better name.

Generally yes. Beware of drinking bottles made from stainless steel. A lot of them are lined with plastic to avoid the metallic taste.

What system would that be? This seems like pure speculation to me so could you elaborate a bit more?

It just sounds like straightforward anti-natalism/extinctionism to me. My wife has a similar mindset

Yes you're right, I completely misinterpreted their comment when I read it this morning.

Though it is a funny Alex Jones quote there might actually be some meat to it.

I think I'm missing something. On the Results in study [b], they say > Semen parameters did not seem affected by caffeine intake, at least caffeine from coffee, tea and cocoa drinks, in most studies. Conversely, other contributions suggested a negative effect of cola-containing beverages and caffeine-containing soft drinks on semen volume, count and concentration. If tea and coffee don't cause an effect, but cola and…

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.
