Testicular Sperm Extraction (TESE) is a minor surgical procedure that retrieves sperm directly from testicular tissue. Fertility specialists use TESE when no sperm is present in a man’s ejaculate – a condition called azoospermia. The retrieved sperm is then used in In Vitro Fertilization (IVF) with Intracytoplasmic Sperm Injection (ICSI) to achieve pregnancy.
A diagnosis of azoospermia does not mean biological fatherhood is out of reach. TESE gives many men with azoospermia a realistic path to having a biological child. The procedure is well-established, low-risk, and performed by reproductive urologists at fertility clinics across the US.
What Is TESE and How Does It Work?
TESE retrieves sperm by removing a small amount of tissue directly from one or both testicles. A laboratory team then examines the tissue under a microscope, identifies viable sperm, and prepares it for use in fertility treatment.
TESE is used specifically for men diagnosed with azoospermia – the complete absence of sperm in ejaculated semen. There are two forms of azoospermia, and TESE applies to both:
- Obstructive Azoospermia (OA): Your body produces sperm normally, but a blockage prevents it from reaching the ejaculate. Common causes include prior vasectomy, infection, or congenital absence of the vas deferens.
- Non-Obstructive Azoospermia (NOA): Sperm production itself is impaired. This may result from hormonal imbalances, genetic conditions, or prior chemotherapy.
Once sperm is successfully retrieved, it is used in IVF with ICSI – a process in which a single sperm is injected directly into an egg to achieve fertilization.
Who Is a Good Candidate for TESE?
TESE is recommended for men who have no sperm in their ejaculate and wish to father a biological child. Your fertility specialist will confirm your diagnosis with a semen analysis and may request bloodwork or a testicular biopsy before recommending TESE.
The procedure is appropriate for men with:
- Obstructive azoospermia from vasectomy or infection
- Non-obstructive azoospermia from a genetic or hormonal cause
- Failed vasectomy reversal
- Azoospermia resulting from prior cancer treatment
TESE is not typically the first choice when other, less invasive retrieval methods are viable. Your urologist will review your full medical history to determine which approach gives you the best chance of retrieving healthy sperm.
How Does TESE Compare to TESA, PESA, MESA, and Micro-TESE?
Several surgical sperm retrieval methods exist. Here is how each one differs:
| Method | Full Name | Technique | Best For |
| TESA | Testicular Sperm Aspiration | Fine needle inserted into the testicle to aspirate tissue | Obstructive azoospermia |
| PESA | Percutaneous Epididymal Sperm Aspiration | Needle inserted into the epididymis to aspirate sperm | Obstructive azoospermia |
| MESA | Microsurgical Epididymal Sperm Aspiration | Microsurgical incision into the epididymis | Obstructive azoospermia, higher sperm yield |
| TESE | Testicular Sperm Extraction | Small incision into the testicle; tissue biopsy | Obstructive and non-obstructive azoospermia |
| Micro-TESE | Microsurgical Testicular Sperm Extraction | Surgical microscope used to identify sperm-producing tubules | Non-obstructive azoospermia; preferred when sperm production is impaired |
According to New Hope Fertility Center, TESA uses a needle, TESE uses a small incision, and micro-TESE adds a surgical microscope for greater precision. Micro-TESE is widely considered the gold standard for men with non-obstructive azoospermia, as it targets tissue most likely to contain sperm.
What Happens During a TESE Procedure?
Before the Procedure
TESE is typically performed in an operating room under sedation, though some clinics perform it in-office with local anesthetic alone, according to Johns Hopkins Medicine. Your care team will advise you on which approach is appropriate and whether to fast beforehand.
During the Procedure
The procedure involves a small incision in the scrotum and the removal of a tissue sample from one or both testicles. A laboratory embryologist examines the sample in real time. If sperm is found, it is either used immediately or cryopreserved for future use. The procedure typically takes 30 to 45 minutes.
After the Procedure
Follow your care team’s post-operative instructions carefully to support a smooth recovery. Based on guidance from Memorial Sloan Kettering Cancer Center, standard recovery instructions include:
- Keep the bandage in place for 2 days after the procedure
- Stay off your feet as much as possible for 3 days
- Shower no earlier than 3 days post-procedure
- Avoid driving while taking prescription pain medication
For micro-TESE, Cambridge University Hospitals advises taking 10 to 14 days off work and avoiding sexual intercourse until you feel fully comfortable. Most men recover completely within a few weeks, according to Cleveland Clinic.
What Are the Success Rates and Risks of TESE?
Success Rates
Success rates vary depending on whether you have obstructive or non-obstructive azoospermia.
- Obstructive azoospermia: Sperm retrieval rates can reach up to 100%, according to a 2019 study published in Systems Biology in Reproductive Medicine (Taylor & Francis Online).
- Non-obstructive azoospermia: Conventional TESE achieves retrieval in approximately 50% of cases (Taylor & Francis Online, 2019). Micro-TESE improves this to 40–60%, according to Cleveland Clinic and the University of Utah Health.
Sperm retrieval does not guarantee pregnancy. Successful fertilization, embryo development, and implantation all affect the final outcome.
Risks
TESE is a low-risk procedure, but like all surgical interventions, it carries some potential complications. According to Tennessee Reproductive Medicine, these include:
- Pain or discomfort at the incision site
- Bleeding or bruising
- Infection
- Swelling
- Rare risk of damage to scrotal blood vessels
Serious complications are uncommon. Discuss your individual risk profile with your surgeon before the procedure.
How Much Does TESE Cost?
Cost varies by procedure type and clinic location. According to Prolistem, conventional TESE typically costs between $3,000 and $10,000. Micro-TESE is more complex and ranges from $8,000 to $12,000, based on pricing information from the University of Utah Health.
These figures do not include the cost of IVF with ICSI, which typically adds $10,000 to $20,000 per cycle. Check with your insurer, as coverage for surgical sperm retrieval varies significantly by plan and state.
Frequently Asked Questions About TESE
Who is the ideal candidate for TESE?
TESE is best suited for men diagnosed with azoospermia – either obstructive or non-obstructive – who want to father a biological child using their own sperm. Your reproductive urologist will evaluate your medical history, hormone levels, and prior semen analysis results to confirm whether TESE is right for you.
What is the typical recovery timeline after TESE?
Most men resume light activity within 3 days of conventional TESE. For micro-TESE, taking 10 to 14 days off work is advised, particularly if your job involves physical labor (Cambridge University Hospitals). Full recovery generally takes a few weeks.
What are the main risks of the TESE procedure?
The most common risks include pain, swelling, bleeding, and infection at the incision site. Damage to scrotal blood vessels is possible but uncommon. Your surgeon will review your specific risks at your pre-procedure consultation.
What are the alternatives to TESE?
Alternatives include TESA, PESA, and MESA, each of which uses different techniques to access sperm from the testicle or epididymis. The right method depends on your diagnosis. Men with obstructive azoospermia may achieve high retrieval rates with less invasive options like PESA. Men with non-obstructive azoospermia are more likely to benefit from micro-TESE.
How much does TESE cost on average?
Conventional TESE ranges from $3,000 to $10,000. Micro-TESE typically costs $8,000 to $12,000. These costs do not include IVF or ICSI. Contact your clinic directly for a detailed breakdown of fees.
Take the Next Step Toward Building Your Family
A diagnosis of azoospermia is not the end of the road. According to Dr. Nudell, TESE has helped thousands of men father biological children through IVF with ICSI, and advances in microsurgical techniques continue to improve outcomes. With the right evaluation and treatment plan, many patients can still achieve their family-building goals.
If you’ve been diagnosed with azoospermia, the next step is a consultation with a reproductive urologist. Your specialist will review your test results, recommend the most appropriate retrieval method, and walk you through the full fertility treatment process.
