Mike Pence proposed an electroshocks treatment. I think that this might be a possibility. There must be something that gets activated in the brain or that do not work correctly, so we might also fix this.
Even in my country, there are clinics offering electric shock therapy for the Sodomite community members. But I don't know how effective this treatment is. How the sexual orientation can be changed by administering electric shock?
Answer is: it is not.
Homosexuality has been considered as a disease for long and no one ever "cured" it even with electroshock or whatever.
The answer is that it's not a disease...
It's a natural phenomenon and you can't do shit about it.
And what the fuck is your country? Where do you live? Saudi Arabia? Syria? Or worse, USA?
