The volumetric procedure was invented by Kurt Freund and is considered to be particularly sensitive at low arousal levels.
Kurt Freund (17 January 1914 – 23 October 1996) was a Czech-Canadian physician and sexologist best known for developing phallometry (the objective measurement of sexual arousal in males), research studies in pedophilia, and for the "courtship disorder" hypothesis as a taxonomy of certain paraphilias (voyeurism, exhibitionism, toucherism, frotteurism, and what he called "preferential rape").

Hebephilia

This meta-analysis extended previous meta-analytic research by showing phallometric responding to both male and female pedophilic and hebephilic stimuli predict sexual re-offence.
According to research by Ray Blanchard et al. (2009), male sex offenders could be separated into groups by victim age preference on the basis of penile plethysmograph response patterns.

LGBT rights in the Czech Republic

Same-sex sexual activity was decriminalized in 1962 after scientific research by Kurt Freund led to the conclusion that homosexual orientation may not be changed (see the History of penile plethysmograph).

Cavernous nerves

cavernous nerves of penis
For prostatectomy nerve-sparing surgery, the surgeon applies a mild electrical stimulation near the cavernous nerves of penis to verify their locations and avoid operative trauma.
During surgery, a doctor may apply a small electrical stimulation to the nerve and measure the erectile function with a penile plethysmograph.

A corresponding device in women is the vaginal photoplethysmograph.

Nerve-sparing surgery

Nerve-Sparing
For prostatectomy nerve-sparing surgery, the surgeon applies a mild electrical stimulation near the cavernous nerves of penis to verify their locations and avoid operative trauma.
It is commonly applied in radical retropubic prostatectomy where surgeons may visually identify the cavernous nerves of penis or apply an electrical stimulation penile plethysmograph diagnostic test to verify the nerves.

Paraphilia

There is some evidence that phallometry can distinguish groups of men with biastophilia (a paraphilia involving rape) from groups of men without it.
He states that while a man's sexual arousal can be directly measured from his erection (see penile plethysmograph), a woman's sexual arousal cannot be measured as clearly (see vaginal photoplethysmograph), and therefore research concerning female sexuality is rarely as conclusive as research on men.
