  journal={Archives of Sexual Behavior},
Eleven nulliparous women manually self-stimulated to orgasm, each on three separate occasions. Pelvic contraction pressure was measured by an anal probe and a vaginal probe simultaneously. Near the perceived start of orgasm, a series of regular contractions began in nine of the women. Anal and vaginal contraction waveforms were synchronized with each other, and the same number of orgasmic contractions occurred in each lumen. Anal pressure had a higher resting baseline and greater amplitude… 
Women's Orgasm
Cognitive-behavioral therapy for anorgasmia focuses on promoting changes in attitudes and sexually relevant thoughts, decreasing anxiety, and increasing orgasmic ability and satisfaction, and studies of brain imaging indicate increased activation at orgasm.
8–13 Hz Fluctuations in Rectal Pressure Are an Objective Marker of Clitorally-Induced Orgasm in Women
This work proposes that outbursts of alpha fluctuations in rectal pressure represent involuntary contractions of muscles in the rectal vicinity, the first objective and quantitative measure that has a strong correspondence with the subjective experience of orgasm.
Orgasm in women in the laboratory—quantitative studies on duration, intensity, latency, and vaginal blood flow
Sexual arousal by clitoral self-stimulation was used by healthy, young adult women volunteers to induce orgasm in the laboratory and data obtained on the duration of orgasm from questionnaires or interviews have suspect validity.
Heart Rate Change as Evidence for Vaginally Elicited Orgasm and Orgasm Intensity
The purposes of this study were a) to further replicate previous findings on vaginal eroticism, using heart rate change as corroborative evidence for the subjective perception of sexual arousal and

The levator contraction upon penile thrusting leads to genital responses that could facilitate sexual performance that comprise widening of the vaginal introitus, vaginal elongation and ballooning of the upper vagina as well as uterine elevation.
An Electrophysiologic Study of Female Ejaculation
The hypothesis that female orgasm is not associated with ejaculation is investigated and it is found that the female orgasm was notassociated with the appearance of fluid coming out of the vagina or urethra.
Relationships among cardiovascular, muscular, and oxytocin responses during human sexual activity
Positive correlations between measures are consistent with a possible functional role for OT in human sexual response and subjective orgasm intensity correlated significantly with increased levels of OT in multiorgasmic women only.
Pontine control of ejaculation and female orgasm.
Activation of a localized region on the left side in the dorsolateral pontine tegmentum, which is termed the pelvic organ-stimulating center, occurs during ejaculation in men and physical orgasm in women.
Is Pelvic Floor sEMG a Measure of Women's Sexual Response?
It is suggested that intravaginal and perianal sEMG respond to erotic stimuli, whereas bulbocavernosal s EMG responses do not.
A new device for simultaneous measurement of pelvic floor muscle activity and vaginal blood flow: a test in a nonclinical sample.
The aim of this study was to test a new vaginal device0-a vaginal photoplethysmograph with build-in surface electromyography (EMG)--that allows simultaneous assessment of pelvic floor muscle activity and vaginal blood flow and to pick up small, involuntary changes in pelvic floor activity associated with anxiety.


The male orgasm: Pelvic contractions measured by anal probe
Pelvic muscle contractions during sexual response can be monitored conveniently by the anal probe method described, and individuals' patterns could be grouped into three types, based chiefly on the location of the regular contraction series within the subjective span of orgasm.
Vaginal and pelvic floor responses to sexual stimulation.
Vaginal vascular responses to vibratory stimulation of the clitoris, recorded as changes in the amplitude of oscillations of light reflectance at the heart-beat frequency, are very repeatable and may be regarded as a tonic counterpart of the well-known phasic bulbocavernosus reflex.
A self‐report investigation of two types of myotonic response during sexual orgasm
Abstract The researchers set out to obtain self‐reports of individual's orgasm reactions in an attempt to discover whether individuals discriminate between orgasms in qualitative terms using
Types of Female Orgasm
The controversy about clitoral versus vaginal orgasms was discussed in Chapter 10. In this article, the Singers offer a new typology of orgasm, which tries to integrate recent physiological research
The “clitoral versus vaginal orgasm” controversy and some of its ramifications
Up until relatively recently in our history there was very little interest in the female sexual response. Women were supposed to be pure and chaste and a lady was not even supposed to be interested
An anal probe for monitoring vascular and muscular events during sexual response.
A method for quantifying physiological changes in the pelvis during sexual response is presented which simultaneously measures changes in blood volume and muscle tension in men and women using an LED-transistor photoplethysmograph and pressure transducer.
Models of female orgasm
A path-analytic model was developed which is consistent with the hypothesis that heterosexual and monosexual behaviors act as mediators between extraversion, neuroticism, and attitudes toward masturbation, and subjective coital or masturbatory orgasmic responsiveness, and the results did not support the concept of a unidimensional orgasm process.

Responses indicated that, on the average, the strength and degree of gratification provided by an orgasm is not related to the method of induction or to the subjective localization of the pulsating sensations.
Sexual Behavior in the Human Female
"Sexual Behavior in the Human Female" was originally published in 1953, five years after the male volume. The material presented in this book was derived from personal interviews with nearly 6,000
