TESA (Testicular Sperm Aspiration)

TESA (Testicular Sperm Aspiration) is a sperm retrieval technique where a fine needle is used to aspirate tissue or fluid from the testicle to look for sperm. It may be used in obstructive azoospermia and in selected cases of non-obstructive azoospermia as part of a comprehensive fertility plan.

TESA (Testicular Sperm Aspiration)

Retrieving sperm when none are seen in semen

What TESA does

TESA aims to retrieve sperm directly from the testicular tissue for use in assisted reproduction—most commonly IVF with ICSI. Retrieved sperm may be used fresh on the day of egg retrieval or frozen for future cycles when possible.

Who may be advised to consider TESA

TESA is considered when sperm cannot be obtained from the ejaculate and sperm retrieval is part of the treatment plan.

• Azoospermia on semen analysis
• Obstructive azoospermia where testicular retrieval is appropriate
• Selected non-obstructive azoospermia cases (case-dependent)
• Failed ejaculation sample on the day of fertility treatment
• When IVF/ICSI is planned and sperm retrieval is required

Step-by-step process

Evaluation and counselling

We review semen analysis, hormone results, and examination findings to select the appropriate retrieval method and explain expected outcomes.

Procedure preparation

We discuss anaesthesia options (often local anaesthesia) and provide clear instructions about medications and aftercare.

Sperm aspiration

A needle is used to aspirate material from the testicle. The laboratory examines the sample to identify and prepare sperm for use or freezing.

Recovery and follow-up

You receive aftercare instructions. Mild soreness or swelling can occur, and we advise when to return to normal activities.

Benefits & success factors

• Minimally invasive approach to testicular sperm retrieval
• Useful in obstructive azoospermia and selected non-obstructive cases
• Can enable IVF/ICSI when sperm are not present in semen
• May allow cryopreservation when sufficient sperm are obtained

Risks or considerations

• Temporary pain, bruising, or swelling is possible
• Small risk of bleeding or infection
• Sperm retrieval is not guaranteed, especially in non-obstructive azoospermia
• Sometimes another retrieval method (e.g., TESE or micro-TESE) is recommended based on diagnosis

FAQs

Is TESA the same as TESE?

No. TESA uses a needle aspiration, while TESE involves removing a small piece of testicular tissue. The choice depends on the underlying cause and expected sperm retrieval success.

Will I be awake during TESA?

Often yes, with local anaesthesia. In some cases, sedation or other options may be used. We will discuss what is appropriate for you.

Can sperm be frozen after TESA?

If adequate viable sperm are retrieved, freezing may be possible. This depends on the sample and the fertility plan.

How long does recovery take?

Most patients recover quickly. Mild soreness or swelling can last a few days, and we advise temporary activity restrictions.

What if no sperm are found?

If sperm are not found, we discuss next steps based on your diagnosis, which may include alternative retrieval techniques or other reproductive options.

When is TESA performed relative to egg retrieval?

It is often coordinated with the partner’s egg retrieval if using fresh sperm. In some situations, sperm retrieval and freezing can be done in advance.
