A woman challenged her GP to a lie detector test to prove he had an inappropriate relationship with her.
Dr Mustak Kapadia, 44, is facing a fitness to practice hearing and could be struck off the medical register.
The locum doctor is accused of giving a female patient his personal mobile phone number and behaving to her in a sexually motivated manner.
The GP, who is now suspended, was working at Strawberry Gardens Medical Practice in Heysham when he allegedly pursued her.
The patient, aged around 40 at the time, gave evidence by video link and told the panel she was “in a very dark place” when Dr Kapadia visted her home in December 2011.
When accused of lying under cross-examination, she broke down and said she was willing to go on the Jeremy Kyle Show to prove she was telling the truth.
Dr Kapadia admitted sending a string of inappropriate text messages between November 2011 and January 2012.
However, it is in December 2011 that he is alleged to have taken things further and the woman alleges he tried to kiss her and then massaged her before she performed a sex act on him.
The pair continued to exchange text messages into the New Year but there was very little contact between them after the alleged incident, the Manchester panel heard.
The hearing continues.
