Hapless lovers are not the only ones who get lost down there: Even sexologists cannot agree on what is what, and where, among women's female parts, according to a father-daughter team of researchers in Italy, Drs. Vincenzo and Giulia Puppo.

In a new review in the journal Clinical Anatomy, Vincenzo, of the Italian Center of Sexology in Bologna, and Giulia, a biologist at the University of Florence, point out some problems with some of newer anatomical and physiological terms researchers have been using since the mid-1990s.

The G-spot? Out. Vaginal orgasm? Out. Female penis? In. It is the best way to refer to female erectile organs, according to the Puppos.
