The arrest of spiritual leader Asaram Bapu for allegedly assaulting a 16-year-old girl and the potency test that he he had to undergo has brought the procedure into the public eye. Many Indians hearing the news that Asaram cleared his potency test, were left asking the question 'what exactly is a potency test?'
A potency test is a medical examination that allows the authorities to prove potency, which basically means that the accused is physically capable of committing sexual assault. With the prime defence in a rape or assault case being impotence, the authorities are well within their rights in requesting or even issuing a warrant for a potency test. So there are three male potency tests which are conducted to prove virility and that the accused, generally an elderly person is in fact physically capable of the crime he is charged with.
The tests are generally conducted by a Uro-Andrologist, who would be part of a hospital's fertility department.
The three tests are;
1. A Semen Analysis: evaluates certain characteristics of a male’s semen and the sperm contained therein. It is done to help evaluate male fertility,
The most common reasons for laboratory semen analysis in humans are as part of a couple’s infertility investigation and after a vasectomy to verify that the procedure was successful. It is also commonly used for testing human donors for sperm donation, and for animals semen analysis is commonly used in stud farming and farm animal breeding.
2. Penile Doppler Ultrasound: This test shows how much and how well blood flows into and out of the penis. It is primarily used for men with Severe Erectile Dysfunction which does not respond to oral medication (like Viagra).
The Doppler effect is used to tell which direction the blood is flowing. In order to have an erection, blood must flow into the penis, but not flow out. But there is a condition know as Venous Leak Syndrome, where the veins do not “shut off” at the right time, so too much blood flows out of the penis, and the erection is not firm. The Doppler ultrasound can find this problem. If this problem exists the only solution is surgery.
Also, erectile dysfunction can be caused by nerve damage, like from diabetes. In this case the nerve signals may not reach the penis, so the blood flow will appears identical to a normal , flaccid penis. In the case of nerve damage, Viagra won’t help, and prosthetic penile implants are required.
3. Visual Erection Examination: During the visual examination the doctor examines the penis in both states, aroused and flaccid, to check for any sort of dysfunction or damage. It also tests Morning Erection in Patients.
