TESA is usually indicated when conventional sperm retrieval methods fail due to underlying male infertility issues. Key causes and risk factors include:

Obstructive Azoospermia

1. Vasectomy or prior vas deferens surgery.

2. Congenital absence of the vas deferens (often associated with cystic fibrosis).

3. Scarring from infections (e.g., epididymitis, mumps orchitis) or trauma.

Non-Obstructive Azoospermia

1. Primary testicular failure due to genetic factors like Klinefelter syndrome.

2. Hormonal disorders affecting spermatogenesis (e.g., low testosterone, pituitary dysfunction).

3. Exposure to chemotherapy, radiation, or toxins that impair sperm production.

Lifestyle and Environmental Factors

1. Excessive alcohol consumption, smoking, or recreational drug use.

2. Chronic stress and obesity affecting hormonal balance.

3. Environmental toxins, including heavy metals and endocrine disruptors.

Understanding the underlying cause of azoospermia is crucial for TESA planning, prognosis, and subsequent fertility treatment.

TESA is not a treatment for a symptomatic condition, but for sperm retrieval in infertility workups. Symptoms and signs that may lead to consideration of TESA include:

1. Inability to conceive after 12 months of unprotected intercourse.

2. Azoospermia confirmed on at least two semen analyses.

3. Small or firm testicles suggesting impaired spermatogenesis.

4. History of prior vasectomy or obstruction in the reproductive tract.

While TESA itself does not address symptomatic disease, it is diagnostic and therapeutic in assisted reproduction, enabling couples to achieve pregnancy using advanced fertility techniques.

TESA is preceded by a comprehensive evaluation of male infertility, including:

Semen Analysis

1. Confirms azoospermia (absence of sperm).

2. Evaluates semen volume, pH, and other seminal parameters.

Hormonal Profiling

1. Serum FSH, LH, testosterone, prolactin to assess testicular function.

2. High FSH may indicate impaired spermatogenesis.

Genetic Testing

1. Karyotype analysis to detect chromosomal abnormalities.

2. Y-chromosome microdeletion analysis for non-obstructive azoospermia.

Imaging Studies

1. Scrotal ultrasound to assess testicular size, architecture, and detect masses.

2. Transrectal ultrasound or MRI for obstruction evaluation in the seminal tract.

Physical Examination

1. Assess testicular size, consistency, and signs of obstruction (e.g., absence of vas deferens).

This thorough workup helps clinicians determine TESA suitability, expected sperm yield, and procedure strategy.

TESA itself is a procedure rather than a disease treatment, but it forms part of a fertility treatment plan.

TESA Procedure

1. Preparation

   1. Local or general anesthesia is administered.

   2. Testicular area is cleaned and prepped to reduce infection risk.

2. Aspiration

   1. A fine needle is inserted into the testicular tissue.

   2. Negative pressure is applied to aspirate testicular tissue containing sperm.

3. Processing

   1. Testicular tissue is examined in the laboratory.

   2. Viable sperm are isolated for ICSI or cryopreservation.

Alternative Sperm Retrieval Techniques

1. Testicular Sperm Extraction (TESE): Surgical excision of small tissue samples.

2. Micro-TESE: Microsurgical retrieval in men with very low sperm production, providing higher yield and minimal tissue loss.

3. Percutaneous Epididymal Sperm Aspiration (PESA): Used in obstructive cases where sperm is accessible in the epididymis.

TESA is often combined with IVF/ICSI, where retrieved sperm is injected directly into the egg, circumventing the need for natural fertilization.

While TESA addresses the consequence of azoospermia, prevention focuses on maintaining male reproductive health:

Prevention

1. Early treatment of infections affecting the testicles or reproductive tract.

2. Prompt correction of cryptorchidism in childhood.

3. Avoid exposure to toxins, radiation, and medications that impair fertility.

4. Healthy lifestyle: balanced diet, exercise, and avoidance of smoking/drugs.

Management Post-TESA

1. Sperm cryopreservation ensures availability for future cycles.

2. Hormonal optimization (testosterone or gonadotropin therapy) if indicated.

3. Psychological support for men and couples facing infertility stress.

Proactive management improves fertility outcomes, reduces repeated procedures, and supports long-term reproductive health.

TESA is generally safe but may have rare complications:

Procedure-Related

1. Bruising or hematoma in the testicle.

2. Infection at the puncture site.

3. Pain or discomfort, usually temporary.

Fertility-Related

1. Rarely, insufficient sperm yield may require repeat procedures.

2. Multiple aspirations may theoretically affect testicular tissue if not performed carefully.

Long-Term Considerations

1. Minimal risk of testicular scarring or vascular compromise.

2. Use of microsurgical techniques minimizes tissue trauma and preserves function.

Careful patient selection, aseptic technique, and expert procedural execution significantly reduce risk.

Emotional Well-Being

1. Infertility can cause anxiety, depression, and relationship stress.

2. Counseling, support groups, and open communication with partners are crucial.

Post-Procedure Recovery

1. Most men resume normal activities within 1–2 days.

2. Mild scrotal tenderness is expected and manageable with analgesics.

Fertility Planning

1. Couples can proceed with IVF/ICSI cycles immediately or use cryopreserved sperm for future planning.

2. Lifestyle optimization enhances sperm quality and overall reproductive health.

Prognosis

1. Success rates are high, particularly in obstructive azoospermia (70–90% retrieval success).

2. Even men with non-obstructive azoospermia have reasonable chances with micro-TESE or repeated TESA cycles.

TESA empowers couples to achieve biological parenthood, transforming the management of male infertility and offering hope for family building.

1. What is Testicular Sperm Aspiration (TESA)?

TESA is a minor surgical procedure used to retrieve sperm directly from the testicles. It is often performed when men have no sperm in their ejaculate (azoospermia) but may still produce sperm in the testes.

---

2. When is TESA recommended?

TESA is recommended for:

1. Obstructive azoospermia (blockage in the reproductive tract)

2. Non-obstructive azoospermia where sperm production is minimal

3. Before in-vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI)

4. Men with previous failed sperm retrieval attempts

---

3. How is the TESA procedure performed?

1. Local anesthesia is administered to numb the area.

2. A fine needle is inserted into the testicle to aspirate fluid containing sperm.

3. The retrieved sperm is examined and prepared for assisted reproductive techniques like IVF/ICSI.

4. The procedure usually takes 15–30 minutes and is minimally invasive.

---

4. Is TESA painful?

Most men experience mild discomfort due to needle insertion, but local anesthesia makes the procedure tolerable. Some mild swelling or bruising may occur afterward, which usually resolves in a few days.

---

5. What is the success rate of TESA?

Success depends on underlying sperm production and testicular health:

1. In obstructive azoospermia, sperm retrieval success is very high (up to 100%).

2. In non-obstructive azoospermia, success ranges from 20–60%.
   Retrieved sperm can then be used in IVF or ICSI, which has separate success rates for fertilization.

---

6. Are there any risks or complications of TESA?

TESA is generally safe, but possible risks include:

1. Mild swelling, bruising, or pain at the injection site

2. Infection (rare)

3. Bleeding or hematoma inside the testicle (rare)

4. Temporary discomfort during urination or ejaculation

Serious complications are uncommon.

---

7. How should I prepare for TESA?

1. Avoid alcohol, smoking, or anti-inflammatory medications for a few days before the procedure.

2. Shave or clean the scrotal area as instructed by your doctor.

3. Arrange transportation if sedation is used.

4. Discuss current medications and medical conditions with your doctor.

---

8. How long does recovery take after TESA?

1. Most men resume normal activities within 1–2 days.

2. Minor swelling or tenderness may persist for a few days.

3. Avoid heavy lifting, sexual activity, or strenuous exercise for about a week, unless your doctor advises otherwise.

---

9. Can TESA affect testosterone levels or fertility long-term?

TESA is minimally invasive and does not usually affect testosterone production or overall testicular function. Fertility in terms of sperm retrieval is preserved, but multiple procedures may slightly increase discomfort or minor scarring.

---

10. What happens after sperm is retrieved by TESA?

1. Sperm is analyzed and prepared in the lab.

2. It is then used in assisted reproductive techniques such as:

   1. Intracytoplasmic Sperm Injection (ICSI) for IVF

   2. Cryopreservation (sperm freezing) for future use

3. The procedure does not guarantee pregnancy, as success depends on egg quality, female reproductive health, and lab techniques.
