TESA (Testicular Sperm Aspiration)

Overview

Testicular sperm aspiration (TESA) is a minor procedure used in male infertility to collect sperm directly from the testicle using a fine needle passed through the scrotal skin. The sperm obtained are then used with ICSI as part of an IVF cycle. TESA is one of several techniques for retrieving sperm when none are present in the ejaculate.

TESA can help men with a blockage preventing sperm from reaching the ejaculate, and some men with reduced sperm production in whom small numbers of sperm may still be found in the testicle. It is minimally invasive and usually done under local anaesthesia. This page is an educational overview only, not medical advice, and no outcome — including pregnancy — can be guaranteed.

Who May Need This

TESA may be considered for men with azoospermia (no sperm in the ejaculate), whether obstructive (due to a blockage) or, in some cases, non-obstructive (a problem with sperm production). It is often used when epididymal aspiration (PESA) has not succeeded.

It requires that at least some sperm are present in the testicle. A fertility specialist or urologist determines suitability after evaluation, and TESA is coordinated with the female partner's IVF cycle.

When It May Be Recommended

TESA may be recommended when a couple is pursuing IVF with ICSI and sperm must be obtained directly from the testicle — because of a blockage that cannot be bypassed, a failed epididymal retrieval, or reduced sperm production.

In difficult non-obstructive cases, a more extensive surgical approach may be advised from the outset because it is more likely to find sperm. The decision depends on individual evaluation and the cause of the azoospermia.

Diagnosis and Evaluation

Evaluation includes a semen analysis confirming azoospermia, a physical examination, and hormone tests to distinguish obstruction from a production problem. Genetic testing is often advised in non-obstructive azoospermia, as it can influence the chance of finding sperm and the risk of passing on a cause.

The female partner is prepared for IVF, since retrieved sperm are used with ICSI or frozen. Your specialist uses these results to plan the retrieval technique and to discuss the realistic chance of finding sperm.

Treatment Options

Sperm-retrieval options include PESA and MESA (from the epididymis), TESA (testicular needle aspiration), and TESE / micro-TESE (testicular biopsy, with micro-TESE using a microscope to find sperm-producing areas in difficult cases).

For obstruction, surgical reconstruction may restore natural sperm flow in selected men. Donor sperm is an option if no sperm can be retrieved. Your specialist recommends the least invasive technique likely to succeed for your diagnosis.

How It Is Performed

TESA is usually performed under local anaesthesia, sometimes with sedation. The specialist stabilises the testicle, passes a fine needle through the scrotal skin into the testicular tissue, and aspirates a small sample. The sample is examined under a microscope to look for usable sperm.

If sperm are found, they are prepared for immediate ICSI or frozen. TESA is quick, and more than one pass may be made. If needle aspiration does not find sperm, an open biopsy technique may be planned as a next step.

Preparation

Preparation typically includes completing tests, coordinating timing with the female partner's IVF cycle, and following medication instructions. If sedation is used you may need to fast and arrange transport home.

If you are travelling for treatment, align the retrieval with the IVF cycle, discuss whether sperm can be frozen in advance, and bring your evaluation and semen-analysis records so the treating team can plan accurately.

Benefits and Expected Goals

The goal of TESA is to obtain viable sperm for ICSI so that biological fatherhood is possible for men with no sperm in the ejaculate. As a needle procedure it avoids a large incision and generally allows a quick recovery.

Benefits vary by individual and by the cause of azoospermia — the chance of finding sperm is higher in obstructive than in non-obstructive cases. Obtaining sperm does not guarantee fertilization or pregnancy. Your specialist can discuss realistic expectations.

Risks and Possible Complications

TESA is generally safe, but possible complications include:

• Scrotal pain, swelling, or bruising
• Bleeding or a blood collection within the scrotum or testicle
• Infection
• Failure to retrieve usable sperm, requiring a more extensive technique
• Rarely, a temporary effect on testicular function

Your specialist will explain the risks specific to your situation. Report severe or increasing pain, swelling, or fever promptly.

Recovery, Follow-up & Aftercare

Recovery is usually quick. Mild scrotal soreness, swelling, or bruising for a few days is common and eased by simple pain relief, scrotal support, and cold packs. Avoid heavy activity and, as advised, sexual activity for a short period.

Follow-up focuses on the retrieval results and the progress of the linked IVF cycle. If sperm were frozen, your clinic will advise on storage and future use. Arrange follow-up with your doctor at home before travelling.

Medical Tourism Planning

If you are considering TESA abroad, choose an accredited fertility clinic with experienced andrology and embryology services, since retrieval and sperm handling must be tightly coordinated with the IVF cycle. Confirm whether sperm can be frozen and understand local regulations.

Plan the timing with the female partner's treatment, request a written treatment plan and cost estimate, and arrange follow-up with your doctor at home. Consider medical travel insurance.

Estimated Cost Factors

Cost depends on the country and clinic, the specialist's fees, anaesthesia, whether a more extensive surgical retrieval is needed, laboratory handling, and sperm freezing and storage. TESA is usually part of the wider IVF-ICSI cost.

Many destinations offer these procedures at a fraction of typical US prices, but figures vary by case. Online prices are only estimates — always request a personalized written quote and clarify what it includes before deciding.

Choosing a Hospital or Specialist

Look for an accredited clinic with a urologist or andrologist experienced in sperm retrieval — including micro-TESE for difficult cases — and a strong embryology laboratory. Ask about their success in finding sperm for your type of azoospermia.

Ask about international patient services, interpreter support, and how the retrieval is coordinated with IVF. Clear, written cost and treatment plans are good signs of a quality clinic.

Alternatives

Alternatives include other retrieval techniques (PESA, MESA, TESE, or micro-TESE), surgical reconstruction for obstruction, and the use of donor sperm if no sperm can be retrieved.

Each option has different invasiveness, success, and considerations. Discuss all of them with your healthcare provider so the plan fits the cause of your infertility and your goals.

Questions to Ask Your Doctor

• Is my azoospermia obstructive or non-obstructive, and how does that affect success?
• Is TESA the best technique for me, or would micro-TESE be better?
• What is the realistic chance of finding sperm in my case?
• Can retrieved sperm be frozen for future cycles?
• Should I have genetic testing first?
• What are the specific risks, and how long is recovery?
• What exactly is included in the written cost estimate?
