State lawmakers approved a bill that, if enacted, would prohibit sex conversion therapy.
The vote was 20-4.
The bill was previously approved by the Gender Equality and Youth Commission.
Those therapies are held in order to forbid LGBTQ members from turning gay.
The bill package was first introduced in November and February by Assemblywomen Julia Andrea Gonzalez and Evelyn Sánchez.
The measure would also modify the Penal Code in order to impose at least two years in prison to those holding or forcing to hold such kind of therapy. The latter has led Governor Marina Avila to suggest vetoing the bill.
