A key step in evaluating male fertility

Testicular biopsy is a specialized procedure used to retrieve sperm through a direct puncture of the testicle for use in assisted reproduction treatments.

It is a fundamental tool in the diagnosis and management of male infertility.

What is a testicular biopsy?

A testicular biopsy is a procedure that allows for the retrieval of sperm directly from the testicles for analysis and, in some cases, to obtain viable sperm for use in assisted reproduction treatments such as in vitro fertilization (IVF) with ICSI.

It is primarily recommended for men with azoospermia (absence of sperm in the semen), men who are unable to ejaculate naturally due to a medical condition, or when other tests have not provided a clear diagnosis of male factor infertility.

No. The procedure is performed under local anesthesia or sedation, so the patient does not experience pain during the intervention.

After the procedure, it’s common to feel mild discomfort in the area, which typically goes away within a few days with proper care and the specialist’s recommendations.

Testicular biopsy is an essential test in the diagnosis of male infertility.

It also offers an option for retrieving sperm in cases where none are found in the ejaculate, allowing for their use in advanced treatments such as IVF with ICSI. This significantly expands the chances of achieving a pregnancy.

The procedure involves extracting a small tissue sample from the testicle, and it can be done in two ways:

  • Percutaneous biopsy: using a fine needle
  • Open biopsy: through a small surgical incision

The choice of technique will depend on each specific case and the specialist’s recommendation.
