Scientists' row over G spot nears a climax

PARIS (AFP) - After more than half a century of debate and bedroom exploration, a row about the location of the fabled G spot may be settled at last, the British weekly New Scientist says.

The G spot, named after a German gynaecologist called Ernst Graefenberg who first mooted its existence in 1950, is said to be a highly sensitive area in the vagina that, when stimulated, gives a woman a powerful orgasm.

But where the G spot is located has been clouded by evidence that is subjective or downright contradictory, and some experts have even concluded that it does not exist.

The answer, according to Italian researcher Emmanuele Jannini, is that, yes, the G spot does exist, but only among those women who are lucky enough to possess it, New Scientist reports.

Jannini, of the University of L'Aquila, used ultrasound to scan a key vaginal area among nine women who claimed to experience vaginal orgasms and 11 who said they didn't.

The target was an area of tissue on the front vaginal wall located behind the urethra. Tissue was notably thicker in this space among the first group of women compared with the second, the scans revealed.

Jannini, who reports the research in full in the Journal of Sexual Medicine, says the evidence is clear: "Women without any visible evidence of a G spot cannot have a vaginal orgasm."

"For the first time, it is possible to determine by a simple, rapid and inexpensive method if a woman has a G spot or not," he believes.

Some experts question whether what Jannini calls the G spot is a distinct structure or the internal part of the clitoris, whose size is highly variable.

Others say more work is needed to confirm Jannini's belief that the G spot is missing in women who don't experience vaginal orgasm. The G spot could be there in all women, but with differing degrees of sensitivity, they believe.

Women who do not have a G spot should not despair, according to the New Scientist report.

"They can still have a normal orgasm through stimulation of the clitoris," said Jannini.

科学研究：女性G点之谜

英国每周发行一刊的《新科学家》发表文章评论：医学界在经过半个多世纪的讨论与两性实验之后，之前吵的沸沸扬扬的“G点”问题，包括它是否存在；如果存在，那具体位置又在哪里等等，最后终于找到了解释。

“G点”一词出自德国妇科医生Ernst Graefenberg名字的首字母。他在1950年时首次假设了它的存在。据说，女性的G点位于阴道内，是个高度敏感的区位。当G点受到性刺激时，可以带给女性很强的性快感。

但是G点的位置到底在哪里，一直以来说法不一。有人说，认为G点存在的想法太主观或完全与事实相悖，有些专家甚至推断根本不存在很么G点。

但是根据《新科学家》的报道，一位意大利的名叫Emmanuele Jannini研究人员对此给出了肯定的回答。G点确实存在，不过只出现在一些幸运的女人身上。

阿布鲁佐大学的Jannini对20名女性进行了超声波实验，结果9名妇女说有性快感，剩下的11人则说没有性快感。

实验的焦点被放在尿道后的前阴道壁组织部分。扫描显示，第一组妇女的组织较第二组的稍厚了一点。

Jannini在《性医学》杂志上全文发表研究成果，认为证据一目了然：女人如果不能亲眼所见G点的存在，那她就不可能产生性快感。

他认为，判断一个女人是否有G点的方法既简单快捷，又节省经费，这还是头一次。

一些专家至今质疑Jannini所说的G点，它到底是单个的结构，还是阴蒂的内部组织，两者的大小大相径庭。

还有不同的声音说，像Jannini所说的那样，G点只在有性快感的女人身上存在，还需要进一步研究证明。

Jannini在报告中说，没有G点的女人不必为此失落因为就算没有G点，女人照样可以通过刺激阴蒂来获得生理上的满足。
