Yeah, to an extent, but the benefits out weight the mild inhibition of it (which I never personally witnessed). I was scared of it for a long time, but I felt better on it especially when you are taking other hormones. Anything that increases metabolism is going to increase enzyme conversion enhancing downstream effects (similar to magnesium).
Coconut oil increases metabolism (thyroid via T3). T3 regulates 5AR and is androgenic, anti-estrogenic along with also increasing androgen receptors. It also contains a similar natural chemical similar to pregnenolone.
Polyunsaturated fats like vegetable oils are estrogenic, anti thyroid and inflammatory- avoid them.
Fin really slowed down our thyroid badly due to the increase in estrogen, prolactin, cortisol and serotonin, which makes sense since thyroid (T3) is androgenic. This is my personal opinion, but I think the reason why everyone's digestion is so screwed up and also immune issues, b/c when the metabolism is slowed from the thyroid being suppressed and body temp is not adequate, candida can grow, not enough HCL acid for digestion, parasites, pathogens etc.
Bacteria/fungus etc. can't survive in high temperature heat (like your optimal body temps or higher)- just like when you get a "fever" when your sick.
Also the increased cortisol levels suppress the immune system. So it is just a viscous circle.
DHT increases body temp via thyroid. DHT is very PRO thyroid, which a lot of it comes down to the "fat loss" effect of DHT and similar androgens. I notice it all the time but when my DHT levels are higher I sweat way more and can eat whatever the fuck I want and stay lean as hell.
And for all you R-andro users androsterone actually is a
