I'm not read up on a lot of literature related to this. I did know that fat stores a variety of different toxins which are released as people lose weight, but i'd be skeptical to link this to low birthrates. The idea that you're drinking womens hormones after an extensive (and often multi-tiered via personal filters) filtration system is a tad far fetched. The burden of proof is definitely on claimant.

As a tangential example, people have made a big deal out of the hormones you ingest from red meat (cows are probably on tren if we're being honest) and that hasn't manifested in any sort of uptick in test levels in the general public. And I'd wager the odds are much greater with direct meat ingestion vs drinking water.

Honestly you could probably exclusively drink egirl piss and not notice anything. Not to mention excess test aromatizes into estrogen anyway, but yeah...
