Favourite treatment or procedure...

Imagine your are doctor or nurse in urology department. What treatment and procedure you like to give for male patient? Why you choose that procedure / treatment?

Penile plethysmography. The combination of chemical and electrical stimulation along with ultrasound would just be fun.

Electroejaculation and cystoscopy for evaluation of semen output from prostate.

After a full examination has taken place (naturally!), my female patient would be tested for arousal and orgasm intensity by electrical stimulation whilst her vital signs are closely monitored.
