Azoospermia patients need to bring all the examination information to the consultation, including previous semen routine, seminal plasma biochemistry, hormone examination, ultrasound, etc., and compare before and after several examinations. Special attention should be paid to the fact that azoospermia patients must be seen in person, and the doctor needs to know in detail whether the patient has had sperm in the past, and whether the woman has a history of conception; to know whether he has suffered from inflammatory diseases such as mumps, testicular inflammation and epididymitis in the past, and whether he has taken medications such as cottonseed oil regularly, which can have a negative effect on the reproductive system. Testicular palpation is also done during the patient’s visit, which is also very important for the diagnosis of the disease. The doctor needs to know the size of the testicles, whether the epididymis is full, and what the hormone levels are, to help determine whether a testicular biopsy might show sperm.
