It is the latest humiliating punishment for the deviant doctor who, it was found, posed an ongoing risk to members of the public.

The case went to trial in 2023 and Nicholas Chapman, from Somerset in the UK, was sentenced to a 12 month community order after being found guilty of one count of attempting to engage in sexual activity without consent.

He was also issued with a 10-year restraining order preventing him from contacting the victim.

His sick actions were uncovered when his victim kept a sample of a drink he made for her after she became suspicious. She reported it to police and DNA tests confirmed a match with the doctor.

The court was told that he had filled up “hundreds” of specimen samples and was accused of adding them to his victim’s drinks.

The victim told the court that after having a sip of one coffee he made for her that she noticed a “salty taste”. When he made others for her she poured them out but saw a “gloopy” substance left in the sink.

A year later when she found a collection of specimens belonging to Chapman, she took a sample of the next coffee he made for her to police, triggering his downfall.

Chapman had claimed in court that he would routinely ejaculate into the toilet due to a medical condition and that the fluid may have ended up in the drink after him not washing his hands. He also later suggested that someone else must have done it as a prank.

In a victim impact statement reported by the BBC at the time, the woman said, “I’ve had to be open about this to my partner and family, but I often feel alone and that no one quite understands.”

“I hope in the future I am able to put this all behind me and move on with my life.

“Though I have to accept that the mental and emotional trauma I have suffered throughout this will always remain with me in some way.”

Judge Rupert Lowe told Chapman: “You are an intelligent professional of previous good character with good references. However, people did not know what you did in private.”

“Your defence at trial was absurd and unnecessary. Your claims were implausible and contradictory.

“You told the police a ridiculous story of having semen on your hand and admitted to masturbating at work. You then shifted your story about testing for a medical condition.

“The truth is, you masturbated at work as you had a high sex drive. The impact on your career and personal life has been considerable. You have brought that on yourself.”

The Medical Practitioners Tribunal Service reviewed Chapman’s case between June 23 and July 8 this year, noting there had been “no evidence of apology, reflection, insight or remediation from Dr Chapman in respect of his conviction”.

As well as the semen in the coffee, allegations about Chapman showing the victim photographs of an erect penis and unclothed women were found to be proved.

Tribunal chair Jonathan Storey said ending Chapman’s medical registration was the “the only sanction that would mark the seriousness of his misconduct and conviction”.

“Erasure would send a message to the medical profession and to the public that this type of behaviour was unacceptable.”
