The invention discloses an early
screening method for
varicocele susceptible people, which comprises the following steps: a detected person statically sits in an examination cabin for 30 minutes, basic information of the detected person is acquired, the detected person takes off clothes of the
whole body, stands 1 meter away from a detection probe of a detection instrument, two legs are slightly separated, two hands are held on the head, and armpits on two sides are exposed; a first
infrared thermogram is shot, the
core temperature of the body is measured, the right side of the examined person is turned by 45 degrees, the tip of the
penis leans against the center of the
abdominal wall upwards through the right hand, pubic hair is pushed aside through the left hand, a second
infrared thermogram is shot, the surface temperature of the
scrotum on the left side is measured, the left side of the examined person is turned by 45 degrees, and the tip of the
penis leans against the center of the
abdominal wall upwards through the left hand; the pubic hair is pushed aside with the right hand, a third
infrared thermogram is shot, the surface temperature of the right
scrotum is measured, relevant data are collected and analyzed, susceptible people with
varicocele are screened out, intervention is conducted in advance, and the incidence rate of
varicocele is reduced.
