1) Penis: Pay attention to whether there are serious phimosis, hard constraints, tumors or abnormal development of inflammation.
2) urethra; no fistula, lower cracks, hard constraints.
3) Prostate: The size of the anal diagnosis can be checked, there are hard constraints, tubers, and can also massage the prostate liquid examination.
4) Testicles: Measure its size, palpation hardness, whether there are hard constraints, tenderness, and pension, whether it is cryptor test.
5) Sacrifice: Touch the hardness of the vasal tubes, whether there are nodules, tenderness, or whether there is an intravenous veins.
2. Laboratory inspection
Except for the semen examination as a compulsory item, the rest should be selected depending on the specific situation of the patient:
