As one of the leading experts in the world on the subject of the so-called “G Spot” and Female Ejaculation, I find it frustrating that the debate on their existence still continues. This is an area of great interest to the public, particularly to women, and every so often the popular media will write a sensationalized story about a scientific study on the question of whether there is any physiological or physical basis for the “G Spot” and Female Ejaculation. With some exceptions, i.e. a 2009 Playboy story[1], these mainstream media stories rarely explore the real issues involved and only seem to be interested in headlines that catch the public’s attention.

Just this last January, 2010, there was a rather poorly done statistical study in the Journal of Sexual Medicine of 1,804 female twins where 56% of the women reported being aware of having a “G Spot”.[2] The conclusion of the article was that either there is not really a “G Spot” OR perhaps 44% of the women did not understand the concept of a “G Spot” and hence were unaware that they had one. The study completely missed earlier statistical studies in the 1980’s of women that came to the exact opposite conclusion to the question of the existence of the “G Spot”. [3] [4]

The mainstream media capsulated the study with titles like, “What an anti-climax: G-spot is a myth” and “Friday Weird Science: the “reality” of the G Spot and the mainstream media.” These stories were controversial and grabbed the public’s attention, but they added little to an understanding of the real issues involved.

In addition to my landmark 1996 study[5], there have been numerous recent scientific studies in the “Journal of Sexual Medicine” involving MRI’s[6], perennial ultrasound[7], and chemical studies[8], that conclusively support the existence of the Female Prostrate (“G Spot”) as an organ and the source of Female Ejaculation.

Once again, I think the problem is in the confusion caused by the use of the term “G Spot” as opposed to the correct anatomical term, which is Female Prostrate. In his article, Gräfenberg only uses the word “spot” twice and he uses it to make the opposite point to the way it has been popularly used. He states that “….there is no spot in the female body, from which sexual desire could not be aroused.” and “Innumerable erotogenic spots are distributed all over the body, from where sexual satisfaction can be elicited; these are so many that we can almost say that there is no part of the female body which does not give sexual response, the partner has only to find the erotogenic zones.”[9]

Therefore, it is logical for scientists and medical doctors to have a problem with the notion there is a single “G Spot” on the anterior wall of the vagina, as opposed to a prostate gland that surrounds the urethra, which is similar to men, and is capable of expelling fluid the same as the male prostrate. Until we become clear about the terms we are using, this controversy will appear over and over again and I will continue to feel frustrated with this matter.
