TESA & PESA – Advanced Sperm Retrieval Techniques at Jananam Fertility Centre
At Jananam Fertility Centre, we offer Testicular Sperm Aspiration (TESA) and Percutaneous Epididymal Sperm Aspiration (PESA) —two highly effective surgical sperm retrieval techniques for men facing azoospermia (absence of sperm in the ejaculate).
For men who cannot produce sperm naturally through ejaculation due to blockages, low sperm production, or previous vasectomy, TESA and PESA provide a direct method of retrieving viable sperm, which can then be used in IVF/ICSI treatments to achieve pregnancy.
By combining expert medical care, cutting-edge technology, and a patient-centered approach, we help couples overcome male infertility and take a step closer to parenthood.

Understanding TESA & PESA – What’s the Difference??
Both TESA and PESA involve surgical sperm extraction, but the approach differs depending on whether the cause of azoospermia is obstructive or non-obstructive.
TESA (Testicular Sperm Aspiration)

TESA is a minimally invasive technique where a fine needle is inserted into the testicle to extract sperm-containing tissue. The extracted tissue is then processed in the laboratory to retrieve live sperm.
TESA is ideal for:
- Non-Obstructive Azoospermia (NOA) – When sperm production is low or absent due to testicular dysfunction.
- Sperm Retrieval for ICSI – Sperm collected via TESA is usually used for Intracytoplasmic Sperm Injection (ICSI).
- Testicular Dysfunction Cases – Such as men with Klinefelter’s Syndrome or those with prior testicular trauma.
