Does Soy actually fuck with your testosterone levels?

Ttl

Probably, though not to the level of microplastics.

I wouldn't normally recommend Wikipedia for something; but, this article does a pretty good job of letting you know what to look out for.

TL;DR: Yes, and so do a lot of things, including nuts, oilseeds, and beer. If you want to counteract that, things like exercise and yelling unironically work at increasing your testosterone.

Don't get too caught up about it though: the dose is the poison etc. If you're only having those sorts of things in moderation and staying otherwise fit and healthy then your testosterone levels won't be tanking.

Yes.

This is just telling you that it makes you cum more.

It is unclear if phytoestrogens have any effect on male sexuality, with conflicting results about the potential effects of isoflavones originating from soy.[1] Some studies showed that isoflavone supplementation had a positive effect on sperm concentration, count, or motility, and increased ejaculate volume.[40][41] Sperm count decline and increasing rate of testicular cancers in the West may be linked to a higher presence of isoflavone phytoestrogens in the diet while in utero, but such a link has not been definitively proven.[42] Furthermore, while there is some evidence that phytoestrogens may affect male fertility, more recent reviews of available studies found no link,[43][44] and instead suggests that healthier diets such as the Mediterranean diet might have a positive effect on male fertility.[44] Neither isoflavones nor soy have been shown to affect male reproductive hormones.[43][45]

Pro tip: add the term "DOI" to your google search to get results that are science journal articles:

Short answer: No.

This idea iirc originates from a letter sent by a doctor to a journal in which he describes an interesting case of a man who grew manboobs - he was essentially allergic to soy and (unaware of this) did nothing but eat tofu, drink soy milk and essentially nourished himself on a largely soy based diet for about 6 months. The long-term aggravated allergic reaction had a ton of side effects, some of them hormonal.
Various rags and clickbait articles then spun this into "SOY CAUSES MEN TO GROW BREASTS!!!!"

Edit: Correction: A 2008 case report of a bloke who had a series of adverse reactions (including manboobs) because he regularly ingested 2 soy products - one being a daily intake of THREE QUARTS of soy milk.
