The existence of an anatomically distinct female G-spot is controversial. Reports in the public media would lead one to believe the G-spot is a well-characterized entity capable of providing extreme sexual stimulation, yet this is far from the truth.
The aim of this article was to provide an overview of the evidence both supporting and refuting the existence of an anatomically distinct female G-spot.
PubMed search for articles published between 1950 and 2011 using key words "G-spot," "Grafenberg spot," "vaginal innervation," "female orgasm," "female erogenous zone," and "female ejaculation." Clinical trials, meeting abstracts, case reports, and review articles that were written in English and published in a peer-reviewed journal were selected for analysis.
The main outcome measure of this article was to assess any valid objective data in the literature that scientifically evaluates the existence of an anatomically distinct G-spot.
The literature cites dozens of trials that have attempted to confirm the existence of a G-spot using surveys, pathologic specimens, various imaging modalities, and biochemical markers. The surveys found that a majority of women believe a G-spot actually exists, although not all of the women who believed in it were able to locate it. Attempts to characterize vaginal innervation have shown some differences in nerve distribution across the vagina, although the findings have not proven to be universally reproducible. Furthermore, radiographic studies have been unable to demonstrate a unique entity, other than the clitoris, whose direct stimulation leads to vaginal orgasm.
Objective measures have failed to provide strong and consistent evidence for the existence of an anatomical site that could be related to the famed G-spot. However, reliable reports and anecdotal testimonials of the existence of a highly sensitive area in the distal anterior vaginal wall raise the question of whether enough investigative modalities have been implemented in the search of the G-spot.
女性 G 点的存在存在争议。大众媒体的报道让人相信 G 点是一个特征明确的实体，能够提供极度的性刺激，但事实远非如此。
本文旨在概述支持和反驳女性 G 点存在的证据。
使用关键词“G 点”、“格拉夫芬伯格点”、“阴道神经支配”、“女性 orgasm”、“女性性敏感区”和“女性射精”，在 PubMed 上搜索 1950 年至 2011 年间发表的文章。选择分析发表在同行评议期刊上的临床试验、会议摘要、病例报告和综述文章。
本文的主要观察指标是评估文献中是否有任何有价值的客观数据来科学评估解剖学上明确的 G 点的存在。
文献中引用了数十项试图通过调查、病理标本、各种成像方式和生化标志物来证实 G 点存在的试验。调查发现，大多数女性认为 G 点确实存在，尽管并非所有相信 G 点存在的女性都能找到它。对阴道神经支配的研究表明，阴道的神经分布存在一些差异，尽管这些发现尚未被证明具有普遍的可重复性。此外，放射学研究未能证明除了阴蒂之外，还有其他任何直接刺激能导致阴道 orgasm 的独特实体存在。
客观措施未能提供强有力且一致的证据证明存在与著名的 G 点相关的解剖学部位。然而，关于在前阴道壁远端存在高度敏感区域的可靠报告和轶事证据提出了一个问题，即是否已经实施了足够的调查方法来寻找 G 点。
