What does it consist of?
In obtaining a small fragment from one or both testicles. This does not affect the function of the organ.
When is it done?
In cases of certain types of infertility in order to establish how the testicle works in relation to the production of sperm (histological study) or to detect whether there are certain genetic problems (cytogenetic study).
How is it done?
With local anaesthesia and on an outpatient basis, one sole incision of 1-2cm is made in the testicular sac. The layers surrounding the testicle are opened up until arriving at same and obtaining a small fragment.
Testicular biopsy technique
How long does it take?
Approximately 20 or 30 minutes.
Are there any complications?
Generally there are no problems. In exceptional cases there may be a hematoma (bruise) of differing intensity.
