Abstract
Atrazine is the most commonly used herbicide in the U.S. and probably the world. It can be present at several parts per million in agricultural runoff and can reach 40 parts per billion (ppb) in precipitation. We examined the effects of atrazine on sexual development in African clawed frogs (Xenopuslaevis). Larvae were exposed to atrazine (0.01–200 ppb) by immersion throughout larval development, and we examined gonadal histology and laryngeal size at metamorphosis. Atrazine (≥0.1 ppb) induced hermaphroditism and demasculinized the larynges of exposed males (≥1.0 ppb). In addition, we examined plasma testosterone levels in sexually mature males. Male X. laevis suffered a 10-fold decrease in testosterone levels when exposed to 25 ppb atrazine. We hypothesize that atrazine induces aromatase and promotes the conversion of testosterone to estrogen. This disruption in steroidogenesis likely explains the demasculinization of the male larynx and the production of hermaphrodites. The effective levels reported in the current study are realistic exposures that suggest that other amphibian species exposed to atrazine in the wild could be at risk of impaired sexual development. This widespread compound and other environmental endocrine disruptors may be a factor in global amphibian declines.
You can just identify as a penis haver. According to troons every identity is true and valid. I for one identify as someone who has 10 penises and all of them have their own personality.

I remember when they were talking about BPA mimicking estrogen and how that was a potential cause of reproductive problems. Alex was then going on about it and then every news outlet was trying to bash him by calling him a kook who thinks juice boxes make fish gay.
I remember that being a serious wake up moment that things are fucked. I wonder if all of this garbage with pollutants has anything to do with troon brain hurts?

...this is literally not news to anybody (except maybe Alex Jones). Also you should see some of the other genetic defects pollutants cause. Some of them are totally metal as shit.
