Introduction to Testicular Sperm Extraction Surgery
Testicular Sperm Extraction Surgery (TESE) is a surgical sperm retrieval procedure used in selected men with infertility. It involves collecting a small amount of testicular tissue and examining the sample in a specialized laboratory to identify sperm that may be suitable for assisted reproductive treatment.
TESE is particularly relevant for patients with azoospermia, a condition in which sperm are not detected in the ejaculate. However, the underlying cause of azoospermia must be established before treatment.
For some patients, surgical sperm retrieval creates an opportunity to use sperm in intracytoplasmic sperm injection (ICSI), a specialized form of assisted reproductive technology.
Nevertheless, successful sperm retrieval is not guaranteed. Therefore, evaluation by an experienced reproductive urologist and fertility specialist is essential.
In this guide, JDMeditech explains testicular sperm extraction surgery, its indications, surgical techniques, instruments, potential benefits, risks, recovery, and frequently asked questions.
What Is Testicular Sperm Extraction Surgery?
Testicular sperm extraction is a procedure in which a surgeon obtains testicular tissue for laboratory examination and sperm retrieval.
Unlike sperm collection through ejaculation, TESE obtains tissue directly from the testis. Subsequently, an embryology or andrology laboratory processes the sample to identify viable sperm.
If suitable sperm are found, they may be used immediately for ICSI or cryopreserved for later treatment, depending on the clinical circumstances.
Importantly, TESE does not correct every underlying cause of male infertility. Instead, it provides a possible method of obtaining sperm for assisted reproduction.
Understanding Azoospermia
Azoospermia means that sperm are not detected in a semen sample after appropriate laboratory examination.
However, azoospermia can result from different medical conditions. Therefore, clinicians distinguish between obstructive and non-obstructive causes before planning treatment.
1. Obstructive Azoospermia
Obstructive azoospermia occurs when sperm production may be preserved, but a blockage or absence of part of the reproductive tract prevents sperm from entering the ejaculate.
Possible causes include previous vasectomy, congenital absence of the vas deferens, or obstruction following infection or surgery.
Consequently, specialists may consider reconstruction or sperm retrieval from the epididymis or testis, depending on the diagnosis.
2. Non-Obstructive Azoospermia
Non-obstructive azoospermia occurs when sperm production within the testes is significantly reduced or absent.
Possible causes include genetic conditions, testicular injury, certain medical treatments, and disorders affecting sperm production.
However, small areas of sperm production may remain in selected patients. Therefore, microdissection TESE may provide an opportunity to retrieve sperm.
Why Is Testicular Sperm Extraction Surgery Performed?
Doctors may recommend TESE when an appropriately evaluated patient cannot provide usable sperm through ejaculation and surgical retrieval is clinically indicated.
For example, the procedure may be considered in selected patients with non-obstructive azoospermia who are planning ICSI treatment.
Additionally, testicular sperm retrieval may be an option in certain cases of obstructive azoospermia.
However, the best approach depends on the cause of infertility, available alternatives, genetic findings, and the couple’s reproductive goals.
Who May Be a Candidate for TESE Surgery?
- Selected men with confirmed non-obstructive azoospermia
- Selected men with obstructive azoospermia
- Patients planning assisted reproductive treatment using ICSI
- Patients in whom other sperm collection methods are unsuitable
- Patients who have completed an appropriate male infertility evaluation
- Patients who understand the possibility of unsuccessful sperm retrieval
Importantly, some genetic diagnoses are associated with virtually no chance of retrieving sperm. Therefore, genetic evaluation and counseling can significantly influence treatment decisions.
What Tests Are Required Before TESE Surgery?
Before recommending surgical sperm retrieval, a reproductive urologist performs a comprehensive assessment.
First, the clinician reviews medical history, reproductive history, previous operations, and relevant medications.
Next, semen analysis is performed or repeated as appropriate to confirm azoospermia.
Furthermore, blood tests may assess testosterone, follicle-stimulating hormone (FSH), and other hormones when indicated.
Selected patients also require genetic investigations, including karyotype analysis and Y-chromosome microdeletion testing.
Additionally, scrotal ultrasound may be used when clinically appropriate.
Consequently, the specialist can recommend an appropriate sperm retrieval strategy rather than proceeding directly to surgery.
Types of Surgical Sperm Retrieval Procedures
Several sperm retrieval techniques are available. However, they differ in the tissue collected, surgical approach, and clinical indications.
1. Conventional Testicular Sperm Extraction (TESE)
Conventional TESE involves obtaining a small sample of testicular tissue through a surgical incision.
Next, the laboratory examines the tissue for sperm. If suitable sperm are found, they may be prepared for assisted reproduction.
However, conventional TESE may be less effective than micro-TESE for selected patients with non-obstructive azoospermia.
2. Microsurgical Testicular Sperm Extraction (Micro-TESE)
Micro-TESE uses an operating microscope to help the surgeon identify and selectively sample seminiferous tubules that may contain sperm.
Furthermore, magnification supports careful examination of testicular tissue and blood vessels.
Current specialist guidelines generally favor micro-TESE for men with non-obstructive azoospermia who are appropriate candidates for sperm retrieval.
3. Testicular Sperm Aspiration (TESA)
TESA uses a needle to obtain material from the testis.
However, TESA is not equivalent to micro-TESE and is generally not recommended as the preferred retrieval technique for non-obstructive azoospermia because of lower retrieval performance.
4. Percutaneous Epididymal Sperm Aspiration (PESA)
PESA retrieves sperm-containing fluid from the epididymis using a needle-based approach.
Therefore, it may be considered in selected patients with obstructive azoospermia.
5. Microsurgical Epididymal Sperm Aspiration (MESA)
MESA uses microsurgical techniques to obtain sperm from the epididymis.
Furthermore, it may be suitable for selected patients with obstructive azoospermia when epididymal retrieval is appropriate.
Difference Between TESE, Micro-TESE, TESA, PESA and MESA
| Procedure | Full Name | Retrieval Site | General Application |
|---|---|---|---|
| TESE | Testicular Sperm Extraction | Testicular tissue | Selected cases of azoospermia |
| Micro-TESE | Microsurgical Testicular Sperm Extraction | Testicular tissue under magnification | Preferred approach for suitable non-obstructive azoospermia cases |
| TESA | Testicular Sperm Aspiration | Testis | Selected cases, usually not preferred for non-obstructive azoospermia |
| PESA | Percutaneous Epididymal Sperm Aspiration | Epididymis | Selected obstructive azoospermia cases |
| MESA | Microsurgical Epididymal Sperm Aspiration | Epididymis | Selected obstructive azoospermia cases |
How Is Testicular Sperm Extraction Surgery Performed?
A qualified reproductive urologist performs TESE in an appropriately equipped clinical setting.
First, the surgical team confirms the diagnosis, planned procedure, and informed consent.
Next, suitable anesthesia is provided according to the procedure and the patient’s medical needs.
During conventional TESE, the surgeon obtains a selected sample of testicular tissue through a surgical approach.
For micro-TESE, an operating microscope supports examination of the testicular tissue and selection of suitable tubules.
Subsequently, the tissue is transferred to an embryology or andrology laboratory for processing and sperm identification.
If sperm are retrieved, the fertility team determines whether they will be used for ICSI or preserved for future treatment.
Finally, the surgeon completes wound closure and provides postoperative instructions.
However, the exact procedure varies according to the diagnosis, surgical technique, and clinical findings.
Essential Instruments Used in Testicular Sperm Extraction Surgery

What Is the Role of Micro-TESE in Male Infertility?
Micro-TESE is particularly important for selected men with non-obstructive azoospermia.
In this condition, sperm production may occur only in small areas of the testis. Therefore, microscopic examination can help identify suitable tissue for laboratory assessment.
Furthermore, evidence suggests that micro-TESE can provide better sperm retrieval outcomes than conventional TESE in appropriately selected patients.
However, success rates vary according to the underlying condition, genetic findings, and patient characteristics.
Consequently, no individual patient should be promised successful sperm retrieval.
Potential Benefits of Testicular Sperm Extraction Surgery
1. Direct Sperm Retrieval
TESE provides a possible method of obtaining sperm directly from testicular tissue.
2. Support for ICSI Treatment
Retrieved sperm may be used for ICSI when appropriate.
3. Treatment Option for Selected Azoospermia Cases
TESE may offer a reproductive option when sperm cannot be obtained through ejaculation.
4. Microsurgical Precision
Micro-TESE provides magnification that helps surgeons examine and selectively sample testicular tissue.
5. Possibility of Sperm Cryopreservation
Suitable retrieved sperm may sometimes be frozen for future treatment.
6. Individualized Reproductive Planning
Sperm retrieval findings can help fertility specialists discuss subsequent treatment options.
7. Coordinated Surgical and Laboratory Care
Collaboration between the surgeon and embryology laboratory supports timely tissue assessment.
Risks and Complications of TESE Surgery
Although TESE is an established surgical technique, complications can occur.
- Temporary testicular pain
- Scrotal swelling
- Bruising
- Bleeding or hematoma
- Wound infection
- Testicular tissue injury
- Possible reduction in testosterone levels
- Testicular atrophy in rare circumstances
- Anesthesia-related complications
- Failure to retrieve sperm
- Possible need for additional fertility treatment
Importantly, micro-TESE may reduce some tissue-related risks compared with conventional TESE. However, complications remain possible.
Can TESE Surgery Affect Testosterone Levels?
Testicular surgery may affect testosterone production in selected patients.
For example, some men experience a temporary decrease in testosterone after sperm retrieval.
Furthermore, patients with non-obstructive azoospermia may already have impaired testicular function before surgery.
Therefore, clinicians may recommend hormonal assessment and follow-up when appropriate.
What Happens If No Sperm Are Found During TESE?
Unfortunately, surgical sperm retrieval does not always identify usable sperm.
If no sperm are found, the fertility team reviews the surgical findings and laboratory results.
Next, specialists may discuss whether further evaluation, repeat treatment, or alternative reproductive options are appropriate.
However, repeat surgery is not suitable for every patient. Consequently, individualized counseling remains essential.
TESE Surgery and IVF/ICSI Treatment
Testicular sperm extraction is often performed as part of a broader assisted reproductive treatment plan.
First, the reproductive urologist evaluates whether sperm retrieval is appropriate.
Next, the fertility team coordinates surgical timing with laboratory requirements.
After retrieval, trained laboratory professionals examine the tissue for sperm.
If suitable sperm are identified, they may be used for ICSI, in which an individual sperm is introduced into an egg using specialized laboratory equipment.
However, successful sperm retrieval does not guarantee fertilization, embryo development, pregnancy, or live birth.
Can Retrieved Sperm Be Frozen?
Yes. In selected circumstances, retrieved sperm can be cryopreserved for future ICSI treatment.
However, sperm quantity and quality may affect the feasibility of freezing.
Furthermore, some patients with non-obstructive azoospermia have very limited numbers of sperm.
Therefore, the surgical and laboratory teams should coordinate the treatment plan in advance.
Recovery After Testicular Sperm Extraction Surgery
Recovery depends on the technique, anesthesia, and individual health factors.
Initially, patients may experience mild to moderate scrotal discomfort, swelling, or bruising.
Furthermore, the surgical team may recommend supportive underwear, prescribed pain relief, and temporary activity restrictions.
Over time, symptoms generally improve after an uncomplicated procedure.
Nevertheless, patients should follow their surgeon’s instructions regarding wound care, bathing, exercise, sexual activity, and return to work.
Postoperative Care After TESE Surgery
- Take prescribed medication as directed
- Follow wound-care instructions
- Wear scrotal support if recommended
- Avoid strenuous activity until cleared
- Attend scheduled follow-up appointments
- Monitor swelling and discomfort
- Follow bathing and dressing instructions
- Discuss laboratory findings with the fertility team
- Ask whether hormone monitoring is needed
Warning Signs After Testicular Sperm Extraction
Patients should seek prompt medical assessment if concerning symptoms develop.
- Severe or worsening testicular pain
- Rapidly increasing scrotal swelling
- Heavy or persistent bleeding
- Fever
- Increasing wound redness
- Unusual wound discharge
- Persistent vomiting
- Other unexpected or serious symptoms
Severe bleeding, collapse, or breathing difficulty requires immediate medical attention.
