New research found no evidence of an erogenous zone in the female vagina.

Despite 56 percent of women reporting having a so-called "G-spot," a King's College London study of identical twins between 23 and 82 says it may only be a figment of a woman's imagination, encouraged by popular culture and sex therapists, rather than , er, hard science.

When comparing pairs of twin sisters, scientists found that genetically identical pairs both reported having G-spots with the same frequency as fraternal ones. (If the sought-after erogenous zone is for real, identical twins -- who share 100 percent of their genes -- should both report having one much more often than non-identical twins.)

Sexologist Beverly Whipple, who popularized the term "G-spot" in the early '80s, disagrees with these findings. She attacks the new study's methodology for, among other things, not finding identical twins who have both slept with the same man. (Thus, it's not that the zone is missing, necessarily, she says, but men who can't find or properly stimulate it.)

Although one has to figure a guy who's bagged twins and lived to tell about it should have the skills to find any G-spot, real or imagined.
