Testicular biopsy in Seville

At Viamed Fertility Institute, we know that receiving a diagnosis of azoospermia, meaning the absence of sperm in the ejaculate, can have a deep emotional impact on a man. However, in assisted reproduction, “not seeing them” does not always mean that “they do not exist”.

Testicular biopsy is the advanced surgical technique that allows us to go directly to the source to retrieve sperm where they are produced or stored, when indicated after prior assessment by the urologist.

From the safe environment of Viamed Hospital Santa Ángela de la Cruz, our medical team works to ensure that male infertility is not the end of the road, but an obstacle that can be overcome with precision and hospital technology.

What are testicular biopsy and epididymal aspiration?

Both are microsurgical techniques designed to obtain sperm when they do not appear naturally.

Although we are talking about a medical intervention, it is a painless process performed under local anaesthesia or sedation, ensuring that the patient feels no discomfort during the procedure at our hospital in Seville.

TESA vs. TESE

which is the best option for your case?

At our centre in Seville, we adapt the technique according to the diagnostic need and the ease of obtaining sperm:

TESA, or percutaneous aspiration

This is the least invasive method. A fine needle is used to aspirate sperm. It is ideal as a first step in cases where we know sperm production exists but there is an obstruction.

TESE, or open biopsy

If aspiration is not sufficient, we perform a small incision to obtain tissue fragments. This allows embryologists to search more deeply within the seminiferous tubules, which is vital in cases of low sperm production, known as secretory azoospermia.

Surgical safety at Viamed Hospital Santa Ángela de la Cruz

Performing a testicular biopsy within a highly complex hospital makes a critical difference to the success of treatment:

Who is this intervention recommended for?

This technique is the definitive solution for men in the following situations:

Vasectomy

Men who wish to become fathers again and do not want to, or cannot, reverse the vasectomy.

Obstructive azoospermia

Due to infections, trauma or congenital absence of ducts.

Secretory azoospermia

When the testicle has production difficulties, but isolated “foci” of sperm production may still exist.

Cystic fibrosis

This is often associated with absence of the vas deferens.

Beyond retrieval

The meiosis study

At Viamed Fertility Institute in Seville, we do not only search for sperm for IVF. In cases of recurrent miscarriage or implantation failure, the tissue obtained during the biopsy can be subjected to a meiosis study.

This cytogenetic analysis allows us to see how chromosomes are organised during sperm production, giving us key answers about why previous treatments may not have worked and how we can help ensure the success of your future Life Project.
