The G-spot is known as the Grafenberg spot and is the term used to denote an area in the vagina that may consist of an erogenous zone. This erogenous zone when stimulated can result in high sexual arousal and intense orgasms. This is however a controversial term and research has been carried out on it since the eighties. There are many countering views about its existence. There are also arguments as to its exact definition and location. Studies on the G-spot in the field of medicine and sexuality are continuing even today.
The term G-spot came about after Ernst Grafenberg, a German gynecologist began researching the existence of this area in 1950. The term was coined later in 1981 by Addiego et al. The initial studies were based on a questionnaire that was circulated to 2350 women. The women who reported the existence of the G-spot also reported that they experienced ejaculation during orgasms. However, many physicians and gynecologists are still doubtful of the existence of this hypothetically erogenous area. The G-spot is supposed to be located on the anterior wall, a few inches inside the vagina. It is said to have the sensation of rippled tissue and is slightly uneven and rough, in comparison to the other areas of the vagina walls. When the G-spot is stimulated, it is said to become swollen and produce powerful orgasms which results in release of a high level of vaginal secretion. There are also some women who report a similar level of sexual arousal when there is stimulation of certain areas in the posterior and anterior vaginal walls at the same depth.
The definition and location of the G-spot as an erogenous zone is based on two methods. The first method is based on women's reports of arousal during stimulation of the area. The second method is based on the notion that stimulating the G-spot results in ejaculation in women. In one study it was found that when the anterior vaginal wall was stimulated, the area grew by 50%. The self reports showed higher levels of arousal during stimulation of the area. The criticism for the existence of the G-spot maintains that the positive evidence has been obtained from small sample groups and as such cannot be considered credible. Also, scientific research that has involved examination of the area in question has put forth that there is no point in the vaginal walls that has a higher concentration of nerve endings.
