A controversial therapy could soon be banned in the city of Rochester.

Mayor Lovely Warren joined a group of supporters outside the Out Alliance Friday afternoon to introduce legislation to city council to put an end to conversion therapy in Rochester.

Conversion therapy is a treatment used to allegedly make a person identify as heterosexual if they’re gay or to conform their gender identity with their biological sex at birth.

Out Alliance Director Jeff Myers says the practice is rejected by most medical professionals and can lead to negative outcomes such as depression, anxiety, drug use, or even suicide.

"It is an absolute amazing opportunity to know that we live in the city that we can live as our authentic selves,” Myers said. “So many folks who come through out center at Out Alliance have been damage by conversion therapy, their lives have been disrupted. They don't know where to go forward because they have been stuck in their past and the hurtful things that have happened. So again on behalf of the Out Alliance and behalf of the entire LGBTQ community I have to say thank you, thank you, thank you!"

New York City adopted similar legislation last year.

Rochester's Pride week starts Saturday.
