Testicular biopsy

To corroborate a diagnosis of infertility and other problems in male sexual health, in many cases, a doctor can recommend a testicular biopsy, so as to diagnose the man’s reproductive potential.

It is a surgery to remove a piece of tissue from the testicles. This tissue is examined under a microscope.

The biopsy can be done in many ways. These are:

  • Open biopsy: In this procedure, the skin of the testicle is cleaned with a disinfectant medication (antiseptic). The area is then covered, and a local anesthetic is applied.  A small incision is then performed through the skin and a small sample of testicular tissue is extracted. At the end, a stitch is placed to close the wound. If necessary, the procedure is repeated in the other testicle.
  • Puncture biopsy: The area is cleaned, and local anesthesia is used, as in the open biopsy. A sample of the testicle is taken using a special needle. This procedure does not require skin incisions.

This procedure is often commonly practiced diagnose the cause of male infertility. It is performed when a sperm analysis suggests that there are abnormal sperm and other problems that may interfere with reproduction in men. In some cases, sperm obtained from a testicular biopsy can be used to perform an in vitro fertilization or IVF.

The risks of a testicular biopsy are:

  • Bleeding
