Surgical Sperm Retrieval

At FIV Valencia, we choose the most appropriate treatment for each case: 100% focused on you.

How Do Techniques Like TESE and MESA Help? 

When no sperm is present in the ejaculate (a condition known as azoospermia), we at FIV Valencia employ these two techniques to obtain the necessary sperm for the best Assisted Reproduction treatment to achieve pregnancy: 

  • TESE (Testicular Sperm Extraction): This procedure involves taking a small tissue sample directly from the testicles to locate and extract sperm, particularly useful when sperm production is limited or impaired. 
  • MESA (Microsurgical Epididymal Sperm Aspiration): This method uses a fine needle to collect fluid from the epididymis, where sperm are stored after production. It is often used in cases where a blockage prevents the normal release of sperm.

When are TESE and MESA Techniques Necessary? 

In Assisted Reproduction, these techniques are recommended in the following cases, where there is/are: 

  • Difficulty retrieving sperm due to erectile dysfunction. 
  • A previous vasectomy. 
  • Only non-viable or dead sperm (necrospermia) present in the ejaculate. 
  • A complete absence of sperm in the ejaculate (azoospermia). 

Success Rates and What to Expect with TESE and MESA 

Your doctor will evaluate your individual situation, including hormone levels and medical history. Our goal is to provide you with all the information needed to understand the success potential of these techniques. 

TESE and MESA offer a highly effective alternative in cases where traditional methods have not succeeded. They allow for direct sperm extraction from where it is produced or stored, providing the opportunity to use viable sperm in Assisted Reproduction treatments such as IVF-ICSI and increasing the likelihood of success. 

These procedures are generally outpatient, involving a relatively quick recovery. 

Obstructive Azoospermia

This condition occurs when there is a blockage preventing the release of sperm. In these cases, the success rate of retrieving sperm can be very high, reaching up to 95%, as sperm production is usually normal.

Non-Obstructive Azoospermia

Here, the issue lies in sperm production. The success rate for finding usable sperm can reach up to 50%, depending on specific circumstances.

Costs of Specialised Laboratory Techniques 

While special laboratory techniques can increase the overall cost of IVF treatment, it’s essential to consider the potential benefits they offer. Costs vary depending on the specific techniques used and the complexity of each case. At FIV Valencia, we provide a detailed cost breakdown upfront, allowing our patients to make an informed decision about

incorporating these advanced methods into their Assisted Reproduction treatment. For more information, please refer to our Price List.

FAQs

What happens to the retrieved sperm?

The retrieved sperm can be used immediately for fertility treatments such as IVF-ICSI (Intracytoplasmic Sperm Injection) or frozen (cryopreserved) for future use, depending on the treatment plan. 

How long is the recovery after TESE or MESA?

Recovery time following sperm retrieval techniques is generally short. Most patients can resume normal activities within a few days, though strenuous activities and heavy lifting should be avoided for about a week after the procedure. 

Are there any risks associated with these procedures?

As with any surgical procedure, there are some risks, such as infection, bleeding, or localized discomfort at the biopsy or aspiration site. However, these risks are low, and these techniques are considered safe. 

Will the quality of retrieved sperm be suitable for fertilization?

The quality of retrieved sperm may vary. In cases of obstructive azoospermia, the sperm are typically healthy and motile. In non-obstructive cases, there may be fewer viable sperm, but ICSI can increase the chances of successful fertilization. 

Can surgical sperm retrieval be repeated if necessary?

Yes, if necessary, the procedure can be repeated. However, this will depend on individual circumstances and should be discussed with your fertility specialist. 

What is surgical sperm retrieval?

Surgical sperm retrieval includes procedures like TESE (Testicular Sperm Extraction) and MESA (Microsurgical Epididymal Sperm Aspiration) to collect sperm directly from the testicles or epididymis. These techniques are used when sperm are not present in the semen due to conditions like blockages or sperm production issues. 

When is surgical sperm retrieval necessary?

In Assisted Reproduction, surgical sperm retrieval is recommended in cases of azoospermia (absence of sperm in the ejaculate), necrospermia (only dead sperm in the ejaculate), a prior vasectomy, or when a blockage prevents sperm release. 

What is the difference between TESE and MESA?
  • TESE (Testicular Sperm Extraction): This involves taking a small tissue sample from the testicles to locate and extract sperm directly. 

  • MESA (Microsurgical Epididymal Sperm Aspiration): A fine needle is used to aspirate fluid with sperm from the epididymis, useful in cases of blockages in the sperm-carrying ducts. 

What are the success rates for these procedures?

Success rates for sperm retrieval techniques depend on the underlying cause. In cases of obstructive azoospermia (related to blockages), the success rate for retrieving sperm can be as high as 95%. In non-obstructive azoospermia (issues with sperm production), the success rate can be up to 50%. 

Is surgical sperm retrieval painful?

These procedures are generally performed under local anaesthesia or mild sedation, minimizing discomfort during the process. Some patients may experience mild pain or swelling afterward, which is managed with pain relievers.
