A doctor from Montclair accused of ejaculating on one of his patients claims that his semen may have gotten onto the 22-year-old woman because he forgot to wash his hands after masturbating, the NY Post reports.

Dr. David Newman, 45, told cops that he masturbated in the lounge before treating the woman for shoulder pain at Mt. Sinai Hospital in Manhattan on Jan. 11, according to The Daily News.

He told police during an interview at his home on Jan. 12 that he believes semen may have gotten onto the patient's blanket and then her face, according to the reports.

Newman allegedly also gave the woman an extra dose of morphine that was not listed on her chart.

Since the accusation, four additional women have come forward and claimed Newman assaulted them, reports say. He is no longer employed at Mt. Sinai Hospital.

Newman is charged with two counts of sexual abuse and facilitating a sexual offense.
