The government in Spain's Catalonia region said Tuesday it was investigating a clinic in Barcelona that is allegedly offering treatments to "cure" homosexuality.
The Policlinica Tibidabo in the Catalan capital is offering pills and psychiatric treatment to "convert" homosexuals, Spanish newspapers said.
Those coming for treatment are often followers of a particular religion who believe homosexuality is incompatible with their beliefs, Spain's leading daily El Pais reported.
"We do not consider homosexuality as an illness, far from it."
She said the clinic could face fines if the month-long probe concludes that such treatments are being carried out.
Homosexuality was only legalised in Spain in 1979, shortly after the death of dictator Francisco Franco whose regime shipped off gays to institutions that some activists have likened to concentration camps.
The Socialist government of Prime Minister Jose Luis Rodriguez Zapatero has sought to promote gay rights as part of a liberal social agenda.
In 2005 it passed a law to allow same-sex marriages, making Spain only the third member of the European Union, after Belgium and the Netherlands, to do so.
