I don't think anyone should be sterilized without their own consent. But in this case, the consent of their guardian should be enough, if it is a temporal form of sterilization.
But this only if there are no other options.
In the case of that woman, why didn't they give her an IUD, implanon or put her on bc pills?
And for guys, there are hormonal treatments which strongly decrease the desire to have sex, or even interest in it.
The thing is that she obviously isn't responsible enough to take them... she really didn't have anyone watching over her. Though I think bc would be a good idea too...for a guardian to make sure happens (if the guardian/government) thinks they need thm.
I think that treatment is a good idea. For males, i think the hormones are just confusing. They would be okay without it.. with it they are confused, putting themselves at risk and others at risk.
