Which part of the female body is named after Dr. Ernest Gräfenberg?

Explanation

The Gräfenberg Spot, often called the G-Spot, is located 2-7 cm inside a woman's vagina.Many women report that it is an erogenous zone which, when stimulated, can lead to strong sexual arousal and powerful orgasms. There is no anatomical proof for the G-spot, however. Some therefore believe that the G-spot is simply a myth created by the German gynaecologist Dr. Ernst Gräfenberg back in 1944. Sometimes the discussion on whether or not the G-spot actually exists continues.
