Conversion therapies are practices that can be defined as any treatment aimed at changing a person's sexual orientation or gender identity. Many different approaches are used including psychotherapy, medication, electroshock therapy, aversive treatments and exorcism. It is generally difficult to obtain data or statistics about the prevalence of conversion therapy because, among other things, it is often done in secret. However, it is estimated that 5% of the LGBTI community have been offered conversion therapies and that 2% have undergone such therapies, but other sources suggest that these figures are much higher. The European Parliament has strongly condemned LGBTI conversion therapies and has made repeated calls on Member States to ban such practices.
