What Is TESE (Testicular Sperm Extraction)?
Testicular sperm extraction (TESE) is a surgical procedure used to retrieve sperm directly from the testicles of men who do not have sperm present in their ejaculate, a condition known as azoospermia. TESE is particularly relevant in cases where conventional sperm collection methods are unsuccessful, most often due to either a blockage in the reproductive tract (obstructive azoospermia) or impaired sperm production (non-obstructive azoospermia). The sperm collected through TESE can be used for assisted reproductive technologies, such as intracytoplasmic sperm injection (ICSI), allowing many men to pursue biological parenthood.
Modern variations, including microdissection TESE (micro TESE), have significantly improved the chances of successful sperm retrieval and reduced the risk of testicular damage. TESE is recognized as one of the most advanced methods for addressing severe male infertility, offering hope when other fertility treatments have failed.
Key Takeaways

Why Is TESE Performed in Male Infertility?
Testicular sperm extraction is a critical intervention in the management of severe male infertility, especially for those with azoospermia—a condition characterized by the absence of sperm in the ejaculate. Azoospermia is found in about 1% of all men and in up to 15% of men diagnosed with infertility (Agarwal et al., 2015). TESE enables many of these individuals to attempt biological parenthood via assisted reproduction procedures.
Common Indications for TESE
- Obstructive Azoospermia: Sperm production is normal, but a physical blockage (such as congenital absence of the vas deferens, prior vasectomy, or scarring) stops sperm from entering the ejaculate.
- Non-Obstructive Azoospermia: The testicles are unable to produce adequate sperm, frequently due to genetic, hormonal, or unexplained factors.
- Prior Vasectomy or Failed Reversal: TESE offers an option for men who want children after vasectomy or after a vasectomy reversal that was unsuccessful.
- Congenital or Acquired Obstructions: Men with cystic fibrosis gene mutations or structural reproductive tract problems may require TESE for sperm retrieval.
Key Point: TESE is reserved for men with absent sperm in the ejaculate, not for those with issues related to sperm motility or morphology.
How Is the TESE Procedure Done?
The TESE procedure is performed by a urologist specializing in male reproductive surgery, typically on an outpatient basis.
General Steps in the TESE Procedure
- Anesthesia: The procedure is usually done under local anesthesia with sedation, though general anesthesia may be used for more complex approaches.
- Testicular Access: A small incision is made in the scrotal skin to access one or both testicles.
- Tissue Biopsy: Small fragments of testicular tissue are removed for examination.
- Sperm Identification: The tissue is handed off to an embryologist, who uses a microscope in the laboratory to search for viable sperm within the sample.
- Sperm Use or Storage: Sperm can be used immediately for ICSI or cryopreserved (frozen) for later use in IVF.
Synchronized IVF
TESE is frequently coordinated with a female partner's egg retrieval, allowing for fresh sperm injection into eggs during the IVF cycle.
Did you know? Many sperm obtained through TESE are non-motile, but can still result in successful fertilization when used with ICSI (Schlegel, 1999).
What Are the Different Types of TESE Surgery?
Multiple testicular sperm retrieval techniques exist, each tailored to different types of male infertility and clinical goals.
1. Conventional TESE
A conventional TESE involves surgical removal of small pieces of testicular tissue with a direct incision. While straightforward and less costly, it may miss sperm-containing areas, especially in non-obstructive azoospermia.
2. Microdissection TESE (micro TESE)
Micro TESE uses high-powered surgical microscopes to identify and extract only seminiferous tubules likely to contain sperm.
- Pros: Higher sperm retrieval rates in men with non-obstructive azoospermia, less tissue removed, and reduced testicular damage (Schlegel, 1999).
- Cons: More time-consuming, requires advanced training and specialized equipment.
3. TESA (Testicular Sperm Aspiration)
TESA employs a needle to aspirate sperm-containing testicular tissue with no incision.
- TESE vs. TESA: TESA is less invasive but has lower success in cases of very low sperm production. TESE (especially microdissection) is preferred in more difficult cases.
4. PESA and MESA (Epididymal Sperm Aspiration)
These techniques target the epididymis (sperm storage just above the testis) and are primarily used for obstructive azoospermia.
Quick Facts Table: TESE Procedure Types
| Method | Invasiveness | Best For | Success Rates | Comments |
|---|---|---|---|---|
| TESE | Moderate | Both types of azoospermia | 30–50% | Standard, straightforward |
| Micro TESE | Higher | Non-obstructive azoospermia | 40–65% | Higher yield, less tissue harm |
| TESA | Minimal | Obstructive azoospermia | 20–40% | May not work in low production |
| MESA/PESA | Minimal | Obstructive azoospermia | 80–100% | Not for non-obstructive cases |
Key Point: Micro TESE is the most effective sperm retrieval technique for non-obstructive azoospermia (Yu & Li, 2018).
How Should Men Prepare for TESE?
Proper preparation optimizes the likelihood of finding sperm and reduces the risk of complications.
Typical Preoperative Steps
- Comprehensive Evaluation: Assessment by a reproductive urologist to confirm the diagnosis, evaluate for reversible causes, and determine the best retrieval technique.
- Hormonal Testing: Levels of FSH, LH, testosterone, and prolactin are checked to gauge testicular function.
- Genetic Screening: Especially in non-obstructive azoospermia cases, for conditions like Klinefelter syndrome or Y-chromosome microdeletions (ASRM, 2015).
- Infectious Disease Testing: Includes screening for HIV, hepatitis B and C, and other STIs, which is standard for assisted reproduction.
- Medication & Lifestyle Review: Patients should avoid substances that impair sperm (e.g., anabolic steroids, chemotherapy), quit smoking, limit alcohol, and manage healthy weight.
- Psychological Counseling: Infertility and surgical treatment are emotionally stressful, so support, counseling, or peer groups may be recommended.
What Are the Risks and Complications of TESE?
TESE is generally safe, especially in experienced hands, but, as with any surgery, some risks remain.
Potential Risks
- Bleeding or Hematoma: Blood can collect, causing swelling and pain.
- Infection: Rare when proper sterile techniques are followed, but possible at the incision site or deeper within the testes.
- Scrotal or Testicular Pain: Typically mild and temporary, but occasionally persistent.
- Testicular Tissue Damage: Excess tissue removal can decrease testosterone production, particularly after repeated or extensive surgeries (Corona et al., 2017).
- Adverse Anesthetic Reactions: As with any surgical procedure.
- Failure to Retrieve Sperm: Not all TESE attempts successfully find usable sperm.
Risks vs. Ways to Reduce Risk Table
| Risk | How to Reduce It |
|---|---|
| Bleeding | Careful surgical technique, avoid blood thinners |
| Infection | Sterile protocols, post-op wound care |
| Testicular damage | Micro TESE use, minimize tissue removal |
| Hormonal changes | Monitor testosterone before and after surgery |
| Pain | Use pain medication, scrotal support |
Did you know? Most men do not experience long-term testosterone reduction after micro TESE, especially if baseline hormone levels are healthy (Corona et al., 2017).
How Is Recovery After TESE Managed?
Most men recover rapidly from TESE, but appropriate aftercare improves comfort and minimizes complications.
Early Recovery
- Pain Relief: Simple painkillers (acetaminophen or ibuprofen) are usually effective.
- Ice Packs: Short-term use during the first 24–48 hours reduces swelling.
- Supportive Underwear: A jockstrap or snug briefs help decrease discomfort and prevent excess movement.
Activity Restrictions
- Rest: Avoid strenuous exercise, heavy lifting, or sex for ~1–2 weeks.
- Incision/Wound Care: Keep the surgical area clean and dry; follow care instructions from your urologist.
Follow-Up
Fuse regular follow-up appointments with your doctor to review wound healing, address any complications, and receive sperm retrieval results.
Key Point: Most men resume light activities within days and typically reach full recovery in two weeks.
What Are Typical Success Rates for TESE?
Success rates for testicular sperm extraction depend on two primary factors: the cause of azoospermia and the technique used.
- Obstructive Azoospermia (OA): Sperm retrieval rates approach 95–100% because sperm production is generally normal; only access is an issue (ASRM, 2015).
- Non-Obstructive Azoospermia (NOA): Sperm retrieval rates are lower, typically 30–65%; microdissection TESE often provides the best results (Schlegel, 1999).
Pregnancy Rates After TESE + ICSI
- Using TESE or micro TESE sperm for ICSI, clinical pregnancy rates are roughly 25–45% per attempt (Esteves et al., 2015).
- The female partner’s fertility, maternal age, and IVF laboratory expertise strongly influence live birth rates.
Factors Affecting Outcome
- Type of azoospermia (obstructive or non-obstructive)
- Testicular health and size
- Age of the male partner
- Experience of the surgeon and embryologist
- Underlying genetic conditions
- Choice of technique (micro TESE vs. conventional TESE/TESA)
How Does TESE Compare to Other Sperm Retrieval Techniques?
Several options exist for testicular sperm retrieval, each suited to specific types of male infertility:
TESE vs. TESA
- TESE: Involves an open surgical biopsy, allowing greater tissue sampling. More effective for men with very low sperm counts or impaired sperm production.
- TESA: Uses needle aspiration, which is less invasive but also less likely to collect sperm when production is minimal.
- Micro TESE is preferred for non-obstructive infertility, while TESA or PESA may be optimal for obstructive azoospermia.
TESE vs. MESA/PESA
- MESA/PESA: Target sperm stored in the epididymis, only suitable when sperm creation is normal but there is a downstream blockage.
- TESE: Necessary when sperm production itself is the obstacle.
Key Point: Choosing the right retrieval method depends on individual diagnosis and should be decided with a reproductive urologist and fertility team.
Frequently Asked Questions About TESE
What does TESE mean in men's sexual health?
TESE, or testicular sperm extraction, refers to a surgical procedure for retrieving sperm directly from the testicles in men with no sperm in their ejaculate due to azoospermia. It is a cornerstone technique for men wishing to achieve biological fatherhood in the context of severe male infertility.
Is TESE a normal procedure for men or couples facing fertility problems?
Yes. TESE is routinely recommended and widely performed for azoospermic men under the guidance of reproductive medicine specialists. It is endorsed by leading reproductive medicine organizations (ASRM, 2015).
Is TESE safe for men?
Generally, TESE carries a low risk of serious complications when performed by an experienced reproductive urologist. Most side effects are mild and short-lived, such as soreness or bruising.
Can testicular sperm extraction affect sexual performance or erections?
TESE typically has no impact on sexual performance, libido, or erections. Rarely, extensive tissue removal or complications may affect hormone production; monitoring testosterone levels is recommended after surgery.
Can TESE improve intimacy, or can it pose relationship risks?
TESE can offer emotional reassurance and hope to couples facing infertility. However, fertility treatments are often stressful and may strain relationships, highlighting the value of strong communication and mutual support.
What are the physical health risks of TESE surgery?
Physical risks include bleeding, infection, pain, and in rare cases, decreased testicular function. These risks are minimized by proper surgical technique and postoperative care (Corona et al., 2017).
Can TESE cause anxiety, guilt, or shame in men?
Yes. Many men experience distress linked to infertility and undergo emotional challenges related to surgical approaches like TESE. Psychological counseling and support networks can help navigate these feelings (Shindel & Nelson, 2013).
How can men practice safety and maintain communication around TESE?
Informed consent and open conversations with your healthcare team and partner are essential. Discuss risks, potential results, and all available options prior to scheduling surgery.
Who should avoid TESE surgery?
TESE is not appropriate for men with untreated severe illness, extremely damaged testicles, or those at high risk of passing on severe genetic conditions as determined by preoperative genetic testing.
How should I talk to my partner about TESE without embarrassment?
Approach the discussion as a shared health challenge, not as a personal flaw. Consider seeking counseling or a session with a reproductive psychologist as a couple.
Is choosing TESE an indicator of deeper relationship issues?
No, TESE is a medical response to a physical problem. However, the emotional strain of infertility and its treatment may reveal or exacerbate other relationship tensions.
What if my partner is uncomfortable with the idea of TESE?
Respect your partner’s concerns and work through them together, possibly with professional guidance. Alternatives like donor sperm or adoption should be explored when needed.
When should I discuss TESE with a doctor or therapist?
Consult a reproductive urologist if you have confirmed azoospermia or have exhausted conventional fertility treatments. Seek mental health support if you or your partner feel emotionally overwhelmed.
How is microdissection TESE (micro TESE) different from standard TESE?
Micro TESE utilizes a high-powered microscope to target areas most likely to contain sperm, leading to higher recovery rates and less testicular damage compared to traditional TESE (Schlegel, 1999).
Can sperm retrieved by TESE be frozen for future use?
Yes. Sperm obtained by TESE or micro TESE can be cryopreserved, though in some cases immediate use with IVF/ICSI, especially when coordinated with partner’s egg retrieval, is preferred.
Does a man’s overall health or lifestyle impact TESE outcomes?
Absolutely. Good general health, eliminating tobacco, managing weight, and limiting alcohol or certain medications can improve both sperm retrieval and recovery.
Is TESE ever repeated if no sperm are found the first time?
Yes. In some instances, especially if the initial attempt was not micro TESE, repeating the procedure may be justified, though success rates often decrease with repeat attempts.
What is the usual recovery period after TESE?
Most men are back to daily, non-strenuous activities within 2–3 days, with full recovery expected within one to two weeks.
How much does TESE cost and is it covered by insurance?
Costs range from $3,000 to $10,000 depending on location and the technique used. Insurance coverage is highly variable; consult your insurance provider for details about fertility benefits.
