The doctor also failed to offer the woman a blanket, despite a support person requesting one. The patient said she experienced significant pain after the procedure.
In its decision, the HDC found the doctor breached professional boundaries by discussing his own health.
The doctor gave evidence that he shared details of his own health with patients to help them understand their condition, and to illustrate how they could manage to cope and lead a reasonably functional life. He also said it was an attempt to be empathetic, and not to minimise the woman's condition.
But the HDC found doing so had minimised and devalued her experience.
It also found he breached standards by failing to conduct a thorough examination, failing to use an assistant, using inadequate sterile precautions, and failing to properly document the procedure.
The HDC recommended he review his practice and report back to the HDC. It also recommended the Medical Council conduct a review of Dr B's competence and conduct.
