I recently listened to an interesting podcast onfrom the New York Times about transgender treatment for adolescents.

The politicians in the USA are trying to (ban this treatment / remove this right) for the first time in two decades, due to the fact that, as they affirclaim, "We have to stop kids thinking they are trapped in the wrong body".

"banning a right" is a pretty unnatural phrase. It's more natural to talk about removing a right. Or if you want to keep the word "ban", you can use "ban this treatment".

Since it's a quotation, it's better to focus on the actions of the speaker. Affirm is also usually not used to introduce a quote.

They believe that (youngs people / youths) may regret their choices.

"youths" is the traditional single word noun for talking about young people of unknown gender, but it's slowly falling out of favour (partly due to how it has been used in American and British politics around "inner city youths", especially young black people), so it's safer to just say "young people" I think.

On the other side others believe that, while a small group is takingwill benefits of from this new law, the majoranceity will suffer.

Politics and medicine arhave never been this entangled before.

"before" puts this sentence in the past so "have" instead of "are"

In the 1980s, the Netherlands was the only state that provided trans treatment for adults (hormones and surgery).

At that time a doctor called Peggy started to investigate about adolescents behaviours on this topic, and discovered that the younger they were, the happier they became after starting this type of treatments.

"this type of treatment" / "these types of treatments" - type and treatment should be considered single or plural together here.

I think in this case, you could go with singular or plural here as long as you're consistent. "this type of treatment" has the idea of a single bucket of treatments (all gender related treatments as group) while "these types of treatments" puts a little more emphasis on there being different subcategories of treatments (e.g. hormones and surgery as different subcategories)

She managed to change the law, allowing 16 years old kids to takhave a choice.

Peggy had a solution even for the youngests: she started sexperimenting with a drug that would stop puberty hormones diffusing in the body.

One day a 13 years old showed up to her office and, after making sure he didn't have any mental issue persuaddriving him, she started this treatment.

As soon as he reached 18 years old he started taking testosterone , since at 16 he was too scared aboutof other people judging him.

Thanks to him Peggy published an article that contribuited in creating ato change: the Dutch Protocol was created, allowing every 16 years old to tmake a choisce about their own body.

"every" is followed by a singular noun

From my perspective, as soon as every (adolescents / teen) is provedn mentally stable, a treatment can be started.

"adolescent" is a pretty formal term, which is not wrong in this context, but I think teen reads a little more naturally here.

I would say "youth", it's not like "i giovani." 😃

adolescents'= the genitive of the plural has the apostrophe after the last letter.

Hmm, I would use persuade more i the sense of convincere. Usually a negative connotation.
