What Is Testicular Sperm Extraction (TESE)?
Testicular Sperm Extraction (TESE) is a specialized surgical procedure designed to retrieve sperm directly from the testicular tissue of men who have little or no sperm in their ejaculate, commonly due to conditions such as azoospermia. TESE is most often performed when less invasive methods of sperm retrieval either have failed or are unlikely to be effective. Through TESE, viable sperm can be obtained for use in assisted reproductive technologies like Intracytoplasmic Sperm Injection (ICSI), allowing men with severe male infertility to have a chance at biological parenthood.
The TESE procedure involves making a small incision in the scrotum to collect pieces of testicular tissue, which are then processed in a laboratory by embryologists to isolate sperm. There are several variations, including microdissection TESE (micro-TESE), which uses a surgical microscope for greater precision and higher success in certain cases.
Key Point: TESE provides a vital option for sperm retrieval in cases where ejaculation does not yield sperm, especially for couples pursuing in vitro fertilization (IVF).

Why Is TESE Used in Men's Health?
Testicular Sperm Extraction is specifically utilized when a man cannot provide sperm through ejaculation—most often because of a diagnosis of azoospermia. Azoospermia is classified as either:
- Obstructive azoospermia: The testes produce sperm, but a blockage in the reproductive tract prevents it from appearing in the ejaculate. This can be due to vas deferens absence (congenital, such as in cystic fibrosis carriers), prior vasectomy, infection, injury, or other conditions.
- Non-obstructive azoospermia: The testes themselves produce few or no sperm at all, often because of genetic factors, hormonal issues, or testicular failure.
TESE is also considered in cases where less invasive procedures—like ejaculation, electroejaculation, or aspiration from the epididymis—are not possible or have failed. It is an important tool in the armamentarium for treating male infertility, especially in couples wishing to use their own genetic material in fertility treatments.
Did you know? Even when no sperm can be seen in a semen analysis, small numbers of viable sperm may still be present in the testicular tissue and can be retrieved for use in assisted reproduction.
How Is TESE Typically Performed?
The process of testicular sperm extraction generally includes the following steps:
- Consultation and Evaluation: The man undergoes assessment by a urologist or reproductive medicine specialist to determine the underlying cause and whether TESE is appropriate.
- Anesthesia: TESE is usually performed under local, regional, or general anesthesia, depending on patient and surgeon preference and the complexity of the case.
- Surgical Approach: The scrotum is cleaned and locally anesthetized. The surgeon makes a small incision in the skin and the underlying tunica of the testis.
- Sample Collection: Small pieces of testicular tissue are removed for examination. In micro-TESE, this is done under an operating microscope to identify tubules most likely to contain sperm.
- Laboratory Processing: The tissue samples are immediately sent to an andrology lab, where they are processed to identify, extract, and (if successful) preserve sperm.
- Cryopreservation (if planned): If IVF/ICSI will not occur on the same day, any viable sperm found can be frozen for future use.
The procedure generally takes from 30 minutes to a few hours, with micro-TESE taking longer due to its meticulous approach.
What Types of TESE Procedures Exist?
Several sperm retrieval techniques may be used, sometimes in combination or as escalating steps:
| Procedure Name | Description | Use Case | Invasiveness | Yield (sperm found) |
|---|---|---|---|---|
| TESE (Traditional) | Small incisions, testicular tissue excised and examined for sperm. | Most forms of azoospermia | Moderately invasive | Variable, 30–60%* |
| Micro-TESE | Uses microscope to identify best tubules for extraction. | Non-obstructive azoospermia | More invasive | Higher, up to 60–70%* |
| TESA (Testicular Aspiration) | Needle-aspirated sample from the testis. | Mild non-obstructive/obstructive azoospermia | Minimally invasive | Modest, 20–40%* |
| PESA (Epididymal Aspiration) | Needle-aspirated sample from epididymis. | Purely obstructive azoospermia | Minimally invasive | High (in suitable patients) |
| MESA (Microsurgical Epididymal Aspiration) | Surgical micro-dissection of the epididymis for sperm | Obstructive azoospermia, failed vasectomy reversal | Surgical | High (in obstructive cases) |
*Success rates vary widely depending on underlying cause, surgeon skill, and patient factors.
Key Point: Micro-TESE generally offers the best yield—and less tissue loss—in men with non-obstructive azoospermia, but also requires significant surgical expertise.
Why Does TESE Matter for Male Infertility and Men's Health?
For many men and couples, a diagnosis of azoospermia can feel devastating. TESE provides a new pathway to fatherhood, especially when natural conception is impossible.
Physical Health Considerations
- Preserves genetic parenthood: Enables a man to have his own child even when unable to ejaculate sperm.
- Lessens need for donor sperm: Reduces emotional burden associated with using donor gametes for some couples.
- Can guide diagnosis: The presence or absence of sperm can provide information on the underlying problem.
Psychological and Emotional Dimensions
- Reduces stigma: Offers hope and therapeutic intervention for a historically stigmatized cause of infertility.
- May improve self-esteem: For men distressed by infertility, a successful sperm retrieval and subsequent pregnancy can be deeply validating.
- Counseling is important: Adjusting to the complex emotions around TESE, success/failure, and the fertility journey can be challenging.
Relationship and Social Implications
- Supports partnership goals: Couples may feel greater unity in pursuing fertility options together.
- Consent and expectations: Clear, mutual agreement is essential due to the emotional and physical complexities.
- Communication required: Partners should talk openly about emotions, risks, hopes, and alternatives.
What Are the Benefits of Testicular Sperm Extraction?
- Pathway to biological parenthood in severe male infertility.
- High success rates with micro-TESE in selected patients with non-obstructive azoospermia (Amer et al, 2022).
- Minimally impacts testicular function when performed correctly.
- Can be synchronized with IVF cycles: Allows use of fresh sperm.
- Sperm can be cryopreserved for future fertility attempts, reducing repeated surgeries.
- May avoid the need for third-party reproduction in some cases.
What Are the Risks, Complications, and Downsides of TESE?
Although generally safe, TESE is a surgical procedure and carries some potential risks. It's important to weigh these against the potential benefits.
Common Risks
- Bleeding or hematoma: Blood can accumulate in the scrotum, causing pain and swelling (PMID: 30392582).
- Infection: Risk exists at the incision or within the testis.
- Scrotal or testicular pain: Usually temporary but rarely persistent.
- Testicular injury or atrophy: Small risk, especially with extensive tissue removal or repeat surgeries.
- Anesthesia complications: As with any procedure requiring sedation or general anesthesia.
- Low retrieval rates: Particularly in severe non-obstructive azoospermia; even with micro-TESE, sperm may not be found.
Less Common Complications
- Damage to blood supply: Can affect testicular function or hormone production.
- Drop in testosterone: Rare; more likely with extensive surgery (PMID: 32535381).
- Scar tissue formation: May affect future surgeries or testicular function.
Risks vs. Ways to Reduce Risk
| Potential Risk | Ways to Reduce/Manage Risk |
|---|---|
| Bleeding | Careful surgical technique, post-op rest, ice |
| Infection | Sterile technique, antibiotics as needed |
| Persistent pain | Gentle handling, appropriate surgical expertise |
| Hormonal disruption | Minimize tissue removal, preoperative assessment |
| Repeat surgery risks | Consider cryopreservation to minimize need for repeats |
Key Point: Most complications are rare, especially with experienced surgeons. Always discuss risk factors specific to your health with your provider.
How to Prepare for a TESE Procedure
Preparation is fundamental both for optimizing success and for safety:
- Comprehensive fertility evaluation: Includes semen analysis, hormone testing (FSH, LH, testosterone levels), genetic screening for chromosomal anomalies (e.g., Klinefelter syndrome, Y chromosome microdeletions), and ultrasound if indicated (PMID: 24268724).
- Psychological counseling: Address expectations, coping with outcomes, and fertility-related stress or anxiety.
- Infectious disease screening: Standard is to check for HIV, hepatitis B/C.
- Coordination with partner’s IVF cycle: If doing fresh sperm retrieval, timing aligns with the female partner's egg retrieval.
- Preoperative instructions: May include fasting, stopping certain medications (e.g., blood thinners), and arranging post-op support.
Recovery and Aftercare After TESE
Although TESE is usually done on an outpatient basis, proper aftercare is critical:
- Pain control: Most men experience mild ache or discomfort that responds to simple painkillers, such as acetaminophen or ibuprofen.
- Swelling/bruising: Common for a few days; use scrotal support (athletic supporter), and ice packs for 20-minute intervals.
- Wound care: Keep the incision clean and dry as instructed.
- Activity restrictions: Avoid heavy lifting, strenuous exercise, and sexual activity for 1–2 weeks or as advised by your surgeon.
- Work/drive: Most men can return to desk work within a few days; more physical jobs may require longer leave.
- Follow-up: Attend all scheduled appointments for wound assessment and to discuss results.
Did you know? The psychological impact after TESE (success or failure) can be significant. Many couples benefit from ongoing counseling and support during this time.
Success Rates, Prognosis, and Alternatives to TESE
Factors Influencing TESE Success
- Type of azoospermia: Success rates are higher in obstructive causes (retrieval rates close to 100%) than in non-obstructive cases (30–60%) (PMID: 29997409).
- Surgical method: Micro-TESE provides the highest retrieval rates; TESA and PESA may yield less sperm.
- Patient’s age and testicular health: Younger men and those without extensive testicular damage have improved outcomes.
- Lab expertise: Experienced embryologists improve the likelihood of locating and selecting viable sperm.
Pregnancy Outcomes
- When TESE-derived sperm are used in ICSI, pregnancy and live birth rates are similar to those using ejaculated sperm, depending on female partner factors (PMID: 24844844).
Alternatives to TESE
- TESA: Needle aspiration; lower yield, less invasive—may be tried first in some obstructive cases.
- PESA/MESA: Suitable if sperm are present in epididymis.
- Vasectomy reversal: Option if prior vasectomy and scarring permit.
- Donor sperm: Considered if no sperm are retrievable or TESE is not feasible or desired.
- Adoption: Non-biological but deeply fulfilling family-building pathway.
Consent, Communication, and Emotional Support
Consent and communication are critical before and after TESE:
- Both partners should agree on pursuing TESE, given its physical and emotional implications.
- Conversations with medical professionals help clarify what to expect and manage realistic hopes.
- Counseling is strongly recommended, especially when considering the emotional impact of a potential negative result.
- Setting expectations: Understanding the likelihood of success, possible need for donor sperm, and the possibility of repeated surgery helps couples navigate the journey.
Scenario Example: A couple, after learning that the man’s semen analyses show azoospermia, discusses their feelings and options with a reproductive urologist, who explains TESE. They participate in counseling to address their worries about infertility and prepare together for the surgical process.
TESE in the Context of Other Medical or Psychological Conditions
TESE may be particularly relevant—or challenging—in men with:
- Low testosterone: Careful assessment and planning required before surgery.
- Genetic syndromes: (e.g., Klinefelter, Y-chromosome microdeletions)—outcomes may vary and genetic counseling is essential (PMID: 28235794).
- Cancer survivors: TESE or micro-TESE may be attempted in those who have become azoospermic after chemotherapy or radiation.
- Previous scrotal/testicular surgery or trauma: Scar tissue may reduce efficacy, or make the procedure more complex.
- Mental health challenges (anxiety, depression): Infertility can exacerbate these; support from mental health professionals can help.
When Should Men Seek Professional Help About TESE?
You should request medical guidance or a specialist consult if:
- Azoospermia is diagnosed: Multiple semen analyses confirm no sperm in ejaculate.
- Other sperm retrieval methods fail: TESE may be necessary as a next step.
- You have a history of risk factors: Such as undescended testis, chemotherapy, testicular injury, or genetic anomalies.
- Chronic scrotal pain post-procedure: Rare, but should be evaluated.
- Emotional distress arises: Infertility diagnosis and its treatments are emotionally taxing; seeking help is a sign of strength.

Frequently Asked Questions About TESE
What does testicular sperm extraction involve?
Testicular sperm extraction (TESE) is a surgical procedure where small pieces of tissue are taken from the testicles to retrieve viable sperm for fertility treatments. It is most commonly used in men with no sperm in their ejaculate (azoospermia). The surgery involves making a small incision and processing tissue to isolate sperm for use in IVF/ICSI.
Who is a candidate for the TESE procedure?
Men diagnosed with azoospermia—meaning no sperm found in semen—are candidates, particularly if the cause is obstructive (blocked tubes) or non-obstructive (testicular dysfunction). Not all cases are suitable, so detailed evaluation by a male fertility specialist is needed.
Is TESE surgery painful?
TESE is performed under anesthesia, so it should not be painful during the procedure. After surgery, mild discomfort, swelling, or bruising is normal and usually resolves within a week with proper aftercare.
What is the difference between TESE and micro-TESE (microdissection TESE)?
Micro-TESE is an advanced form of TESE where the surgeon uses a high-powered microscope to find areas of the testicle most likely to contain sperm, improving retrieval rates and minimizing tissue loss (PMID: 23374861). Micro-TESE is especially beneficial for non-obstructive azoospermia.
TESE vs TESA: What’s the difference?
TESE involves surgically removing pieces of testicular tissue, while TESA is a needle aspiration technique where testicular fluid is sampled through the skin. TESE, especially micro-TESE, typically has higher sperm retrieval rates, particularly in non-obstructive cases.
Can sperm retrieved by TESE be frozen for later use?
Yes, sperm isolated through TESE can often be frozen (cryopreserved) for later use in IVF/ICSI, which can help minimize the need for repeat surgeries (PMID: 29565797).
What is the TESE success rate?
Success rates depend on the underlying cause. In obstructive azoospermia, sperm can almost always be retrieved. In non-obstructive cases, retrieval rates range from 30% to 60%, varying by technique and center experience.
Are there risks of TESE damaging my testicles or hormone levels?
The risk of permanent damage is low, especially with proper technique. Rarely, testosterone production can be affected, but most men have no significant long-term consequences.
How long does it take to recover from the TESE procedure?
Most men return to light activities in 2–3 days and resume normal activities after 1–2 weeks. Careful wound care and avoidance of strenuous activity speed up recovery.
Can TESE be repeated if sperm is not found the first time?
It may be possible to repeat TESE, especially with newer or more advanced methods like micro-TESE. However, retrieval rates may be lower with repeat surgeries.
What should I discuss with my partner and doctor before TESE?
Discuss your fertility goals, realistic chances of success, alternatives in case no sperm are found, emotional readiness, costs, and the impact on your relationship. Counseling is recommended for all couples.
Does TESE work for all types of male infertility?
No. TESE is specifically helpful for men who have sperm production or transport problems causing azoospermia. It doesn't treat all forms of male infertility (such as issues with sperm function or quality in men with sperm in their semen).
Can lifestyle changes improve my chances of success with TESE?
Stopping smoking, moderating alcohol, managing weight, and treating underlying health issues may help optimize testicular function but do not guarantee success, especially if genetic or severe testicular problems exist.
What are the alternatives if TESE does not retrieve sperm?
Options include using donor sperm for IVF, pursuing adoption, or considering other surgical retrieval techniques if appropriate.
Is TESE covered by insurance?
Coverage varies widely. Some insurers may cover the procedure when it's linked to a clinical diagnosis of infertility, but others may not. Always check with your insurance provider.
When should I see a doctor or urologist about TESE?
If you or your partner are struggling with conception and semen analyses show no sperm, or if you are considering IVF and have a history of vasectomy or testicular issues, see a reproductive urologist for evaluation.
Are there any long-term psychological effects of undergoing TESE?
Infertility, surgical intervention, and fertility treatments often carry a psychological burden. It's common and normal to feel stressed, anxious, or disappointed; professional counseling and support are recommended.
How does TESE fit into the overall process of IVF/ICSI?
TESE is used to retrieve sperm when no sperm are available in the ejaculate. The sperm can then be combined with eggs (usually via ICSI) to fertilize embryos in the IVF process.
What is the cost of TESE surgery?
Costs may range from several thousand to many thousands of dollars, depending on the country, clinic, and complexity (e.g., micro-TESE is more expensive). Many clinics offer payment plans, but insurance coverage should be clarified in advance.
