Since ancient times, men have never lost their attention to the penis. The function of the penis and testicles often affects the male reproductive system and sexual ability. However, with the development of the economy and the increase of age, men are facing more and more mental pressure. Many men find that their sexual ability is far worse than before. At this time, appropriate medication and exercise intervention are very necessary. Next, let us learn about the relevant content of using penile blood flow to test sexual ability. Penile flow index (PFI): It is a non-invasive method to measure the blood supply status of the penis. It is generally believed that PFI < 6 indicates normal penile blood vessels; if PFI > 6, angiography will show lesions. The closer the occlusive lesions are to the small arteries of the penis, the greater the PFI value.Normal value PFI < 6 indicates normal penile vascularity. Clinical significance Abnormal result: If PFI> 6, then the angiography will show the lesion. The closer the occlusive lesion is to the penile arterioles, the greater the PFI value. People who need to be examined: Patients with sexual dysfunction.
Unsuitable people: patients with penile injuries. Pre-examination contraindications: (1) The examinee must make an appointment in advance; (2) Before the examination, the examinee must explain his/her usual erectile function and ejaculation latency to the doctor; (3) A few days before the physical examination, pay attention to your diet. Do not eat too much greasy or indigestible food, do not drink alcohol, and do not take medications that may damage liver and kidney function; (4) The day before the physical examination, you should take good rest, avoid strenuous exercise and emotional excitement, and ensure adequate sleep to avoid affecting the physical examination results. It is best to take a shower. Requirements during the examination: (1) Do not be shy or nervous during the examination, as this may accelerate blood flow and affect the examination results. (2) Lie flat on the tester during the examination and do not move around randomly. (3) Cooperate actively with the doctor and take good care of the equipment.
The patient is asked to lie flat on the tester. The ultrasound probe emits ultrasound waves to the human blood vessels. The probe receives the echo signal to obtain the average blood flow velocity, test the penile cavernous arteries, and automatically calculate the penile blood flow index (PFI value) through a computer to determine whether the sexual dysfunction is caused by vascular lesions. It can also be used to test systolic and diastolic pressures.
