However, a disadvantage of this modality is that it is invasive, and necessitates the use of radiolabeled compounds. Sexual arousal in women: the development of a measurement device for vaginal blood volume.
Sildenafil improves sexual functioning in premenopausal women with type 1 diabetes who are affected by sexual arousal disorder: a double-blind, crossover, placebo-controlled pilot study. The response was found to be highly variable and it did not consistently increase in response to pelvic nerve stimulation In addition, the electrode records oxygen diffusion across the skin, reflecting transient changes in blood flow It has been measured by a number of methods, including pH, filter papers and tampons.
Given this conflicting data, the vaginal thermistor will need to be assessed in future studies to determine its usefulness as a measure of sexual response. Sometimes there is a temptation to focus on physiology and anatomy, but we must not forget that the brain with all its psychological, social and emotional components, may be most important organ in female sexual function.
The data revealed that there was evoked and spontaneous clitoral electromyography that likely indicates a sympathetic tonus of the clitoris, similar to that of the corpus cavernosum of the penis in males In that study evaluating clitoral blood flow, they observed high positive correlations between examiners for measurement of maximum velocity, resistance, and pulsatility
Furthermore, we are not certain of the clinical significance of many of these measures. GSR can be performed in 2 ways, active and passive. The publisher's final edited version of this article is available at Fertil Steril. WoodardM. Given all of these limitations, some argue that physiologic measures lack standardization and are not suitable for use in large-scale clinical trials, citing that there are a number of validated surveys and questionnaires that are better suited for this purpose Studies that use instruments designed to measure female sexual function.
In his experiments, he applied electrodes to these erogenous zones which included areas such as the penis, vagina, tongue, lips, and othersmeasured them, and found that there were differences.
Neuroanatomical correlates of visually evoked sexual arousal in human males. Photoplethysmographic evidence for vasomotion in the vaginal circulation—drug induced vasodilation changes both the vaginal pulse amplitude and the ratio of low to high pulses recorded in the basal trace; Paper presented at the International Academy of Sex Research; Helsinki, Finland.
Normative values for female genital sensation. No significant differences were found in blood flow before and after the procedure. The publisher's final edited version of this article is available at Fertil Steril. The Genitosensory Analyzer GSA is used to measure temperature and vibratory sensation of the genitalia.
