Magnetic resonance imaging of male and female genitals during coitus and female sexual arousal

Thank you for the excellent images and report. I am a retired doctor
of Chiropractic. I have several reference books, but I cannot find any
good explanation of the physiology and mechanism of an orgasm. I have had
a prostatectomy and can still have an orgasm, though not as pleasurable as
before my operation. Since I do not have to manufacture semen, I should be
able to have orgasms every few minutes. But there is a very long
refractory period- sometimes days. It appears to me that there must be
some component involved in orgasm.

I would appreciate any information you can send to me.

Thank You
