That’s a bit of twist: in fact amphibians, like humans, start out all female - atrazine just interferes with the development of male characteristics, making male frogs develop intersex or even completely female characteristics.

Can you elaborate on humans starting out all female ? Are you talking about the women's egg chromosomes ? I wouldn't call that a human.. an embryo has a strong claim to being a human, but an egg ?

[cluckindan]

A human embryo is a human embryo. It cannot develop into an apple or a zebra.

Not with that attitude it cant!

what was the relevance of this comment?

[bena]

All embryos start out biological female, it’s only after some time that the testosterone kicks in and differentiates males from females.

If you block that process, you’d wind up with an XY female.

Swyer syndrome being the representative example of this for those looking for more info.

I thought that would be considered intersex as there are some anatomical structures that do not rely on the testosterone to develop minimally, such as udecended (non/minimally functioning) testicles in an XY individual who has external femal genitalia.

[bena]

If you would call that intersex, then go for it. I'm not here to argue the semantics. These are edge cases that are fairly complicated.

We're talking about a person with a uterus, vulva, vagina, etc. But without the widening of hips or development of breasts that happen in most women. No penis, no scrotum, no vas deferens, no testosterone. Nothing you would find in the majority of men.

The only thing they have are testes and the testes present in these individuals are basically inert. They're usually removed because they're more likely to develop testicular cancer.

With hormone therapy, they will develop the secondary sex characteristics of women.

But the overall point here is that atrazine would need to be administered in utero to have the effects claimed by Alex Jones. Frogs reproduce externally. They lay eggs that are then fertilized. These eggs can be contaminated with surface atrazine which would then affect their development as described earlier.

so we need to ensure that pregnant women avoid atrazine, from sources such as drinking water

Note: the claim was “they’re turning the frogs gay!!” which is quite inaccurate in several aspects (who’s “they?”). The general thrust is correct, however.
