Rapper Dr. Dre has lost his longstanding battle with a gynecologist of the same name. In 2015, Dr. Drai, a Pennsylvania-based gynecologist, filed to trademark his name - Doctor Drai - and won the right to keep using his trademark name.

But according to the gynaecologist's application, he has been going by the name Dr. Drai for many years. He has authored books and even made public appearances using it.

Although Dr. Drai's talents lie in the anatomy of the human body, the rapper had tried to pump the brakes on that application, claiming it would cause confusion in the marketplace since their names sound alike.

Andre Romelle Young, better known by his stage name Dr. Dre, is an American rapper, record producer, and entrepreneur. He is the founder and current CEO of Aftermath Entertainment and Beats Electronics.
