Testicular biopsy is often recommended when semen analysis shows a complete lack of sperm. It can help determine if the issue is due to a blockage (obstructive azoospermia) or problems with sperm production within the testicles (non-obstructive azoospermia).
Additionally, testicular biopsy is performed to retrieve sperm directly from the testicles when it is not present in the semen. The extracted sperm can then be used for IVF procedures.
Testicular biopsy may also be recommended when the cause of male infertility is unclear, and after other tests like semen analysis and hormone testing have not provided a definitive diagnosis. The biopsy can help identify underlying conditions like testicular cancer or other abnormalities that may be impacting fertility.
