TESA & PESA Services Advanced Sperm Retrieval Procedures

When a male partner is unable to produce sperm in the ejaculate due to obstructive or non-obstructive azoospermia, advanced sperm retrieval procedures like TESA (testicular sperm aspiration) and PESA (percutaneous epididymal sperm aspiration) offer a reliable solution. These methods allow embryologists to collect viable sperm directly from the male reproductive organs for use in ICSI (intracytoplasmic sperm injection) as part of an IVF cycle.

What is PESA? (Percutaneous Epididymal Sperm Aspiration)
PESA is a minimally invasive technique to collect sperm directly from the epididymis — the tube where sperm are stored and matured. It is often performed under local anesthesia and is typically used in cases of obstructive azoospermia, such as after vasectomy or due to congenital blockages.

Ideal For:
Obstructive azoospermia

• Men with prior vasectomy
• Congenital absence of vas deferens

How it works:

A fine needle is inserted through the scrotal skin into the epididymis to aspirate sperm, which are then used for ICSI.

🔍 What is TESA? (Testicular Sperm Aspiration)

TESA is a slightly more invasive method than PESA, where sperm are directly aspirated from the testicular tissue using a needle. It is used when sperm production is severely impaired or no sperm are found in the epididymis.

✅ Ideal For:

• Non-obstructive azoospermia (poor sperm production)

• Failed PESA cases

• Men with hormonal or testicular issues

How it works:

A needle is inserted directly into the testicle to extract a small tissue sample. Sperm cells are then retrieved from that tissue in the IVF lab.

📈 Success Rate

While both methods are effective:

• PESA has higher success rates in obstructive cases

• TESA is more useful for non-obstructive conditions but may need repeat attempts

Success also depends on the embryologist’s skill, lab quality, and proper case selection — which is why PRAVI Global IVF follows international standards in andrology and embryology.
