An Orthodox scientific group has sparked controversy by giving a platform to a Jewish organisation that believes homosexuality can be cured.
The Association of Orthodox Jewish Scientists invited Arthur Goldberg to speak at its annual convention in Connecticut last month.
Mr Goldberg is a proponent of reparative therapy, which seeks to transform gays and bisexuals into heterosexuals through therapy.
In 1999, he co-founded JONAH (Jews Offering New Alternatives to Homosexuality). Opponents claim such therapies are ineffective and even harmful.
