The 36-year-old was arrested in 2010 in Himachal Pradesh and is being tried in Bangalore. He told the city court that is trying him that he is like a child and not capable of having sex. The court then ordered a series of medical tests, which he appealed against in different courts.
Nithyananda disappeared from his Bangalore ashram four years ago after local television channels ran footage that allegedly showed him in a compromising position with an actress.
He was located and arrested in Himachal Pradesh nearly two months later. Four of his associates from the ashram have also been charged with rape.
A US-based woman has also alleged that she was sexually abused by Nithyananda for five years, a charge denied by him. Other women disciples then claimed that they had been asked to have sex with him and his associates.
Nithyananda had a huge ashram on the outskirts of Bangalore.
