COVID-19 is surrounded by a lipid envelope; soaps break down lipids.

Yes, and you don't need an anitbacterial soap for that. A regular soap will be fine.

Yeah, but jon worded it like antibacterial soap would be ineffective (due to this being a virus), but it's not.

So, a quick rebuttal to this trash blog post recounting a trash publication. This is a cut-and-paste from a real rebuttal (Dore & Chignol, Fertility & Sterility, 2012), transcribed here for easy browsing. Link at the end:

"We think that the evidence presented in this article cannot support the claim that the observed effects are non-thermal and caused by exposure to a Wi-Fi radiofrequency electromagnetic field."

1. Keeping constant the temperature under the computer by an air conditioning system is not sufficient to ensure homo-geneity of the temperatures within the experimental area, be-cause the heat source from the laptop is not homogenous itself, and to exclude that there is no local variation in the samples temperatures. If the exposure design can be justified by the desire of being as close as possible to the actual conditions of use of a lap-top computer, the dosimetry used in these experiments is much too simplistic. There is no indication of the homogeneity of the field under the laptop, which may greatly depend upon the location of the Wi-Fi antenna within the computer.

2. The control samples,‘‘kept in another room away fromany computers or electronic devices,’’were not actually keptunder identical conditions. A more suitable experimental de-sign would have been a sham exposure design in which con-trol samples would have been exposed under the sameactively working computer, but with its Wi-Fi emission turned off.

3. Moreover, Avendano et al. state that‘‘[radiofrequency electromagnetic waves] from mobile phones may cause DNA damage’’and that‘‘research has shown negative consequences of electromagnetic fields on biological mechanisms,’’and they cite in support of their contention a highly controversial article(cite2). Genotoxicity of radiofrequencies is not a matter of opinion: radiofrequency energy absorption cannot break DNA molecules, and it should be kept in mind that there is no known biologically plausible mechanism by which non-ionizing radio waves of low energy can disrupt DNA(cite3). Recently, while classifying radiofrequency electromagneticfields (RF-EMF) as‘‘possibly carcinogenic to humans’’(group2B), the International Agency for Research on Cancer Working Group reached the overall conclusion that there is only weak mechanistic evidence relevant to RF-EMF–induced cancer in humans(cite4)

The conclusion of the rebuttal: "There is a serious message behind our rebuttal. Citing Avendano et al.(cite1) among the evidence of an association between Wi-Fi exposure and a genotoxic effect on humans perm would demonstrate how studies with an erroneous methodology can be used to support important public health claims and also the weakness of the evidence purporting to demonstrate a non thermal effect of Wi-Fi RF."

What's so wrong with a biscuit?

Like I said, I was going for the nuclear option and biscuits have sugar in. Sugar makes you fat. Fat belly means less testosterone. This is part of the anti-western diet thing.

> Sugar makes you fat.

Nonsense. Overeating makes you fat, not a specific carb. Having a biscuit with a few grams of sugar is not going to impact your health in a meaningful way if you're not overeating.

In my experience, Teflon will always be scratched. Yes, in theory you could "use it correctly", but nobody ever does. So it's better to simply not have them.

Whats a good alternative? The ceramic ones?

It may be difficult to get to happen in your relationship, because at least for me, my partner is insistent on using non-stick pans. If you have to have non-stick, ceramic or hard anodized are much healthier than teflon, although they aren't as non-stick so require some adjustments to cooking style.

The best things to use are cast-iron and cladded stainless steel. With both, you heat the pan more slowly to reach your appropriate temperature (you're looking for leidenfrost) and then you add oil, and cook. If you use healthy oils and heat before adding the oil, cast-iron is effectively non-stick once a seasoning develops and cladded stainless steel won't stick except with specific foods (eggs). But this is definitely a different methodology for cooking than most people are familiar with.

The other benefit of using non-teflon pans is you can use all types of utensils.

In my (layman’s) review of related literature, this seems to be the case. I’ve gone through phases of looking into for eg. what might optimise lean mass, testosterone, longevity, decrease cancer risk, sperm count etc. It’s all basically the same stuff. Unsurprising, really.

Can you share your study/findings? It'll help me and others who are searching for the same.

I’m afraid I don’t have comprehensive notes, but it’s not very complicated or new (perhaps disappointingly). Maintain a lowish bodyfat (10-15% for males, I think 20-30% for females), consume sufficient nutrients (including non-famous ones like k2) but lower-than-you’d-think calories, get enough but maybe not too much sleep, minimise stress, avoid endocrine disrupters (though if memory serves evidence here is thin), cold and hot treatments both have potential benefits (e.g suana), exercise is good (both aerobic and resistance). Fasting and/or low carb can improve the efficacy of radiotherapy in cancer treatment. Things like that.

You said "temporarily", so I want to remind you that all the same things are harmful to a child's development, especially when their systems are just coming online and establishing their baselines.

Yes absolutely! Still doing the dietary things for her. She gets to have hot baths though, and wear tight fitting underpants. FYI anyone else reading, if you have a boy Teflon is really something you should avoid.

I'm duplicating this text higher up, lest it be buried deep in the argument below:

> At normal cooking temperatures, PTFE-coated cookware releases various gases and chemicals that present mild to severe toxicity.

> Only few studies describe the toxicity of PTFE but without solid conclusions.

> There are some reports where PFOA was detected in the gas phase released from the cooking utensils under normal cooking temperatures.

> Due to toxicity concerns, PFOA has been replaced with other chemicals such as GenX, but these new alternatives are also suspected to have similar toxicity.

> The toxicity and fate of ingested PTFE coatings are also not understood.

Just want to share what I learned from personal experience:

Don't give up on winning over your partner's mind. It may take a little while, and you have to be patient, diplomatic, and gentle. People are resistant to change. But it is not hopeless, and it is worth it in the end, because their health is at stake.

Weight loss and proper exercise will probably deliver 99% of the improvements for 99% of the people. Stressing about heat, radiation, micro plastics, or other random stuff seems like extra stress for not that much benefit. Most people in Western world are either out of shape, or straight up obese. It makes sense that, that will have huge negative effects on fertility.

We tried for several months but after starting and following a workout regimen for a few weeks... it just happened! It's amazing what a little exercise can do for your body!

> following a workout regimen for a few weeks.

This got a chuckle out of me sir.

I imagine the sperm sent you a memorandum of protest about your unhealthy lifestyle. Sure it was an illegal strike but it worked.

Enamel Ceramic Cast iron Stainless steel In that order, in my opinion.

You left out the two I’ve been considering, hard anodized and high carbon steel. Any reason why?

We've switched to carbon steel from cast iron; while it's easy to warp the carbon steel (and we have), it still works fairly well on our electric range. The seasoning is just as good as cast iron. A heavier high carbon steel pan might avoid the warping issue, but ours are all pretty thin.
