First, the main study that all of this is based on: Small study, only 5 ppl UV lamp (NOT sun!) was applied to the either the chest or genital region of men for ⬆️ amt of time (up to 20 min) across consecutive days (up to 5) https://tahomaclinic.com/Priva...

So what happened? "After 5 irradiations of the *chest*, the hormone output [androsterone] was ⬆️ to 155 i.u./L, that is, an ⬆️ of 120%" "After 5 irradiations [of the *genitals*] during 6 days, the androsterone excretion was ⬆️ from 70 to 205 i.u./L, nearly 200%" Not bad

What happened after UV exposure was STOPPED? Chest: "5 days w/o tx, output fell back to 80 i.u./L...examination 2.5 wks later showed it to be again 70 i.u./L" Genitals: "10-day interval w/o irradiation, hormone output went back to its ‘normal’ level of about 70 i.u./L"

We can assume something happened while the UV lamp was applied This effect faded away once the UV lamp exposure was removed Theory: What if the UV lamp was detoxing/destroying testicular toxin(s) while applied, only to have the testicles re-toxify after the UV lamp was stopped?

Let's clear something else up first All studies I've seen on T changes d/t light exposure in animals & humans are done w UV lamps NONE were w sunlight This is important "They" say: - sunlight=bad - tanning=bad - rat poison D3 supps (TeraD3 & D-Con)=good I say the opposite

It's not very scientific to: - use studies to claim UV light benefits are the *same as the sun* - while also claiming that UV lamps & tanning beds are *all bad* Pick a side, bucko This site is great & debunks fearmongering garbage science on UV/tanning: https://www.thetanningguru.com...

Big question: Is there a compound that is BOTH known to be toxic to testicular function AND that is detoxed/destroyed by UV light? Yes. Yes, there is This compound is the toxin known as "vitamin" A I'll elaborate (you know I always do)

Let's show some studies in actual humans Then we'll get to (much less valuable) cell-based (in vitro) studies The human studies always trump everything else While we're here, you should know there is NO DIFFERENCE in toxicity bw NATURAL & SYNTHETIC forms of "vit" A, see below:

On to the human (in vivo) studies ⬆️ "vit" A in Egyptian men, ⬇️ testosterone Study: Estradiol Testosterone Ratio, Serum Retinol Binding Protein 4 and Insulin Resistance in Overweight and Obese Egyptian Men http://ibimapublishing.com/art... Results following

⬆️ RBP4 levels, which mean ⬆️ "vit" A levels were assoc w: ***⬇️ testosterone*** ⬆️ estrogen ⬆️ estrogen to testosterone ratio (bad) ⬆️ Body Mass Index (BMI), aka fatter men ⬆️ waist circumference, aka fatter belly ⬆️ insulin resistance (bad) THAT'S BAD. What about women?

Same thing in women Study: Retinol-binding protein 4 is elevated & is associated with free testosterone & TSH in postmenopausal ♀️ NOTE: Retinol-binding protein-4 is a valid surrogate test for blood "vitamin" A levels What did it show?

In postmenopausal women: ⬆️RBP4 levels aka ⬆️ "vit" A = ***⬇️free testosterone*** ⬆️TSH (bad) In premenopausal women: ⬆️RBP4 aka ⬆️ "vit" A = ⬆️BMI aka fatter women None of that is good Sure does establish a pattern in HUMANS though! https://link.springer.com/arti...

Now that I've demonstrated that more "vit" A floating around the blood equals lower Testosterone Does "vitamin" A damage the testicles in other ways, such as related to sperm production (the recent hot topic for health goo-roos to tweet about)?

"Animal Vit A" aka retinol, damages sperm-producing Sertoli cells: Study: Retinol supplementation induces oxidative stress & modulates antioxidant enzyme activities in rat sertoli cells https://pubmed.ncbi.nlm.nih.go...

"Active Vit A" (all-trans retinoic acid) destroys sperm-producing Sertoli cells: "RA at high doses (1-10 microM) ⬆️ TBARS levels & induced a ⬇️ in cell viability" Viability = the ability to function adequately That's not good https://pubmed.ncbi.nlm.nih.go...

"vit" A damages sperm-making & transporting tubes "all-trans retinoic acid completely inhibited seminiferous cord formation" Are you seeing the pattern yet? https://pubmed.ncbi.nlm.nih.go...

Any human evidence of "vit" A weakening sperm? "men who consumed organ meats had significantly ⬇️ progressive sperm motility & ⬆️ LH levels than men who did not consume organ meats" For most, organ meats = liver = "vit" A ⬆️LH = ⬇️ T levels https://ncbi.nlm.nih.gov/pmc/a... More below

More reproductive system destruction Accutane is 13-cis retinoic acid & is an "active" form of "vit" A in the body Some of the retinol you eat turns into Accutane aka 13-cis retinoic acid, there is no denying this biochemistry See images below for what "active vit A" destroys

What happens when MALE baby mice can't break down retinoic acid ("active vit A")? "in which endogenous RA is not degraded, develop mild ovotestes, but more important, steroidogenesis is impaired & the reproductive tract feminized" Ovaries in their balls https://pubmed.ncbi.nlm.nih.go...

Did you know pharma is researching male birth control via STOPPING the detoxification process of "vit" A? Must be pretty toxic to the balls then! See below FYI, female birth control has been shown to ⬆️ "vit" A in blood since 1975 (for a future thread) Weird coincidences, no?

After all that evidence of "vit" A damaging, mutating, and debilitating normal testicular function... Does UV light detox/destroy "vit" A? "ultraviolet irradiation causes a functional vitamin A deficiency" Yes. Yes, it does this via oxidation https://www.nature.com/article...

Scrotal (ballsack) skin is not very thick, and light easily penetrates it This is why UV light applied to the balls caused a greater ⬆️ of T than the chest It directly detoxes/destroys "vit" A in the balls Both approaches work, 1 worked better This is the connection

@NutriDetect Doc. How about IR light for your thyroid? There is good research on that… IR light for your balls is a NO GO!!!

@SaludStrategica I have not looked into it If you have links to IR for the balls being bad, pls share

@NutriDetect @SlfImprvmntKrg So you’re against liver consumption as it is high in vitamin A?

@suny0urballs @SlfImprvmntKrg To put it mildly. Make sure to read both parts of this thread: https://mobile.twitter.com/Nut...

@NutriDetect So for those who can't scrot-sun, I take it a UV lamp is a viable replacement?

@LaddybirdXmd That's what the original study was done with, so yes

@NutriDetect Any thoughts on a natural sunscreen to cover tattoos with?

@AdiSxBridge Zinc oxide based

@NutriDetect See 'Sun worship exercise'.. old school eastern medicine.. bathing anus area and genitals in the sun.. feel the sunlight penetrate the tissues. Other exercises utilise low light (sunrise and sunset), for naturally boosting phyiological processes. 😊🖐

@NutriDetect @SASWARPIG Observe their weird flexes. Empathize with them. Talk about what they are really worried about. You'll never have to say "balls".

@NutriDetect @ngolotesla what do you think of UVB lamps?
