A doctor has appeared in court accused of giving a woman a cup of coffee which contained his own semen.

Nicholas Chapman, 54, denies two charges of trying to engage a woman in sexual activity without her consent.

One incident allegedly happened on September 13, 2021, and the other is said to have happened between September 12, 2020 and September 12, 2021.

Chapman, of Kingston St Mary in Taunton, is said to suffer a medical condition which means he produces excess semen, and remnants could have been unintentionally transferred to the coffee.

Prosecutor Richard Posner told the trial at Gloucester crown court that the woman had discovered a ‘suspicious gloopy substance’ at the bottom of her cup after the doctor made her a coffee.

Mr Posner said: ‘The woman became concerned about the taste of the coffee that Dr Chapman had made her on a number of occasions and she recalls spitting it out.

‘On September 13, 2021 she was throwing away the contents when she saw a gloopy substance in the bottom of the cup.’

The woman contacted police and was told to put the evidence in the freezer. She handed it to police three days later and a test confirmed the substance was semen and DNA evidence led back to Chapman.

She then told police it was not the first time a cup of coffee made for her by Chapman had ‘tasted funny’.

When he was arrested later that month, he said in response: ‘That is one hell of an allegation to make.’

Chapman says he has a medical condition called prostatitis, which produces excess semen and he deals with this when he is in the toilet on a daily basis.

In his defence, Virginia Cornwall said: ‘Dr Chapman did not have any sexual interest in this woman and did not behave inappropriately towards her.

‘He denies making the woman her coffee on that day and states that he denies putting anything in her coffee at any time.

‘Dr Chapman can only assume that somebody else put his semen into the coffee as he collects it on a regular basis and places the contents in plastic bottles and undertakes his own testing of it.’

The trial continues.
