In a testicular biopsy tissue from the testicles is collected and examined in the microscopy to extract spermatozoids. There are several methods depending on the reason for the exam. Your doctor will inform you about your options.
The biopsy is made in cases where spermatozoids have not been found in the semen analysis and other tests have not succeeded. In some cases, the collected spermatozoids can be used for in vitro fertilization.
A testicular biopsy can also be performed if tumours or rare masses are found. If a test, such a testicular ultrasound, suggests there may be a tumour in the testicle, the doctor may recommend a biopsy to determine if the tumour is benign or carcinogenic.
