You contradict yourself in the very next sentence.

"helping" a doctor do their function is not the same as being "convenient" for a doctor. Especially in the context of "a lying down position", which makes "helps the doctor" imply a functionally needed assist in the child birth. Being "convenient" is further expanded on in my last paragraph, and it in no way has anything to do with functionally "helping" the child birth.
