女性“G”点：带来性快感，减轻分娩痛
路透社纽约健康消息-研究发现，女性性敏感地带，即所谓的“G”点，不仅能引起性快感，还可以减轻分娩的痛苦。
G点位于阴道内壁的前端，靠近尿道和膀胱颈。大约在50年前，德国的产科医生恩丝特·古瑞芬贝格(Dr. Ernst Grafenberg)就对女性的性敏感地带进行了描述，“G点”中是G字就是取自于其名字的第一个字母。从那以后，许多科学家致力于研究G点是否存在以及其存在原因。一些动物研究表明，G点有使痛觉迟钝的作用，提示了它有着除产生性快感以外的其他作用。
美国新泽西州路特吉斯大学的贝丽弗·薇普博士(Dr. Beverly Whipple)领导的研究小组从20世纪80年代早期就开始研究动物研究成果是否可以延伸到人类身上。他们的研究结果一再证明答案是肯定的。研究报告发表在最近一期的《斯堪的那维亚性学杂志》上。
他们进行的十几次研究一次又一次发现：刺激G点可以显著地提高女性的痛阈；在分娩过程中按压G点有自然的止痛效果。

对墨西哥嗜好辣椒的女性的研究提供了更多的证据。薇普博士注意到，在她所在的地区，说西班牙语的妇女分娩过程中表现得特别痛苦，开始她认为这是文化差异造成的，她们不会掩饰痛苦。后来她的研究小组发现，这些爱吃辣椒的妇女在刺激G点后痛阈并不会提高。辣椒含有辣椒素，老鼠实验证明辣椒素可以降低G点的止痛效果。因此她开始怀疑到是辣椒素在作怪。辣椒素可能破坏了一种特殊的神经纤维，而这种神经纤维正是使G点有天然止痛作用的关键。
可以想象到，如果没有G点的话，妇女分娩将会更加痛苦。
The ``G‘‘ Spot May Govern Pleasure And Pain
NEW YORK (Reuters Health) - A woman‘s erogenous zone may exist for more than mere pleasure. Researchers say evolution may have designed the so-called ``G‘‘ spot to ease the pain of childbirth.

The German obstetrician Dr. Ernst Grafenberg--the ``G‘‘ in G spot--first described the female erotic zone some 50 years ago. Since then, researchers have wondered exactly why, and if, the G spot exists. Some animal research suggested the G spot has a pain-dulling effect, which suggests it has a role beyond pleasure.
Since the early 1980s, Dr. Beverly Whipple and her colleagues have looked at whether this animal research might extend to women. Their work has consistently shown that it does, according to Whipple, of Rutgers University in Newark, New Jersey.

``We hypothesize that childbirth would be much more uncomfortable without the G spot,‘‘ she told Reuters Health.
Whipple reported on her research in a recent issue of the Scandinavian Journal of Sexology.
She said that the G spot appears to be at the front of the vaginal wall, near the urethra, the neck of the bladder. In about a dozen studies, Whipple‘s team has found that stimulating this area in women significantly increases their pain threshold. Pressure on the G spot seems to create a natural analgesic that comes into play during childbirth.

Whipple said she found more evidence of this when she studied women in Mexico who enjoyed diets rich in chili peppers. Chili peppers contain a chemical capsaicin, which has been shown in lab rats to dull the pain-killing effects of the G spot.
Whipple said she began noticing that Spanish-speaking women in her area seemed to have particularly tough times during labor. ``At first I assumed it was a cultural difference, and they felt more free to express pain,‘‘ Whipple said.

But the animal research on capsaicin led her to suspect a different culprit: chili peppers. In their study of Mexican women, Whipple and her colleagues found that women who ate diets high in chili peppers did not have their pain thresholds raised when their G spots were stimulated. Capsaicin, she said, appears to destroy particular nerve fibers that are key to the G spot‘s natural pain-blocking effect., http://www.100md.com
