Orgasm is a complex, multimodal reflex induced typically by genital stimulation. Genitally stimulated orgasms (GSOs) activate excitatory neurochemical pathways in the brain and spinal cord that ultimately stimulate sympathetic outflow and the inhibition of parasympathetic spinal circuits in the lower lumbar cord. However, some women claim to have orgasms spontaneously without genital stimulation.
To report the case of a 33-year-old woman who developed the ability to attain and control the duration of a subjective orgasmic state without genital stimulation after tantric training.
Blood was taken at weekly intervals before, during, and after spontaneously-induced orgasms that lasted 5 or 10 minutes, or after a 10-minutes period of book reading. Plasma was analyzed using ELISA for luteinizing hormone, follicle stimulating hormone, free testosterone, and prolactin. The woman also provided subjective scores for different types of orgasms using the Mah and Binik (2002) Orgasm Rating Scale (ORS).
Prolactin levels post orgasm increased by 25% and 48%, respectively, after the 5- or 10-minutes non-genitally stimulated orgasm (NGSO), and were still elevated from baseline 30 minutes after orgasm. No changes were observed in FSH or free testosterone. The pattern of sensory, affective, and evaluative orgasm ratings after a 10-minutes NGSO was similar to orgasms induced by clitoral or anal stimulation. Book reading did not result in any change in prolactin.
Prolactin surges after orgasm are an objective marker of orgasm quality. The increase in prolactin after her NGSOs indicate that they induce the same physiological changes as GSOs and result from "top-down" processing in the brain.

性高潮是一种复杂的多模式反射,通常由生殖器刺激诱发。生殖器刺激引发的性高潮(GSOs)会激活大脑和脊髓中的兴奋性神经化学通路,最终刺激交感神经输出并抑制下腰段脊髓中的副交感神经回路。然而,一些女性声称在没有生殖器刺激的情况下能自发达到性高潮。
报告一名33岁女性的案例,该女性在接受密宗训练后,具备了在无生殖器刺激的情况下达到并控制主观性高潮状态持续时间的能力。
在持续5分钟或10分钟的自发诱导性高潮之前、期间和之后,或在10分钟的读书时段之后,每周采集一次血液。使用酶联免疫吸附测定法(ELISA)分析血浆中的促黄体生成素、促卵泡激素、游离睾酮和催乳素。该女性还使用Mah和Binik(2002年)的性高潮评定量表(ORS)对不同类型的性高潮给出主观评分。
在5分钟或10分钟的非生殖器刺激引发的性高潮(NGSO)之后,性高潮后的催乳素水平分别增加了25%和48%,并且在性高潮后30分钟仍高于基线水平。促卵泡激素或游离睾酮未观察到变化。10分钟的NGSO后的感觉、情感和评价性高潮评分模式与阴蒂或肛门刺激引发的性高潮相似。读书未导致催乳素发生任何变化。
性高潮后催乳素激增是性高潮质量的客观标志。她的NGSO后催乳素的增加表明,它们引发了与GSOs相同的生理变化,并且是由大脑中的“自上而下”处理过程导致的。Pfaus JG, Tsarski K, 一例无生殖器刺激的女性性高潮案例。性医学2022;10:100496。
