TESA (Testicular Sperm Aspiration) in Bangalore
Testicular Sperm Aspiration (TESA) is a minimally invasive sperm retrieval procedure used for men who have very low sperm counts or no sperm at all in their ejaculate — a condition known as azoospermia. Rather than relying on naturally ejaculated sperm, TESA retrieves sperm directly from testicular tissue using a fine needle, allowing men who would otherwise be unable to father a biological child to still do so through assisted reproductive techniques like IVF or ICSI (Intracytoplasmic Sperm Injection).
TESA is one of several sperm retrieval options available in male fertility treatment, and is typically considered the simplest and least invasive of these techniques — making it an accessible starting point for many men before more advanced retrieval methods are explored.
How TESA Works
The procedure is quick, generally performed as a day-care outpatient procedure under local anesthesia. Here's what to expect:
-
Local anesthesia: The scrotal area is numbed to minimize discomfort during the procedure.
-
Needle aspiration: A fine needle is inserted directly into the testicle, and gentle suction is applied to draw out a small sample of testicular tissue and fluid.
-
Sample examination: The aspirated sample is immediately examined under a microscope by an embryologist to identify and isolate viable sperm.
-
Sperm freezing or same-day use: Depending on the treatment plan, retrieved sperm can be used fresh (if timed with the partner's egg retrieval) or cryopreserved (frozen) for future use in IVF/ICSI cycles.
The entire procedure typically takes 15–30 minutes, and most men can resume normal activity within a day or two.
Who Needs TESA?
TESA is generally recommended for men who have:
-
Obstructive azoospermia — sperm production is normal, but a blockage (from a previous vasectomy, infection, or congenital absence of the vas deferens) prevents sperm from reaching the ejaculate.
-
Very low sperm counts where natural conception or standard IUI/IVF using ejaculated sperm isn't a viable option.
-
Failed vasectomy reversal, or situations where reversal isn't the preferred route.
-
Certain cases of non-obstructive azoospermia, though outcomes here are less predictable, and more advanced techniques like Micro-TESE are often considered first for these cases.
A thorough diagnostic work-up — hormonal blood tests, scrotal ultrasound, and sometimes a testicular biopsy — helps determine whether TESA is likely to retrieve usable sperm, or whether a different retrieval approach would offer better odds.
TESA vs. Other Sperm Retrieval Techniques
Several sperm retrieval methods exist, and the right choice depends on the underlying cause of infertility:
-
TESA — needle aspiration directly from testicular tissue; simplest, least invasive, good first option for obstructive causes.
-
PESA (Percutaneous Epididymal Sperm Aspiration) — needle aspiration from the epididymis rather than the testicle itself; often used when the blockage is at the epididymal level.
-
Micro-TESE (Microscopic Testicular Sperm Extraction) — a more advanced, microscope-guided surgical extraction used primarily for non-obstructive azoospermia, where sperm production itself is impaired and needs to be located within specific areas of testicular tissue.
Your fertility specialist will typically recommend the least invasive option likely to succeed first, escalating to more advanced techniques only if needed.
What Happens to the Retrieved Sperm?
Sperm retrieved through TESA is not used for natural conception — it's specifically intended for use with ICSI, a specialized form of IVF where a single sperm is injected directly into an egg. This is necessary because TESA-retrieved sperm is often present in very small quantities and may have limited motility, making conventional IVF fertilization less reliable. If a same-day retrieval isn't coordinated with the partner's egg retrieval cycle, sperm can be frozen and stored for use in a future cycle.
Success Rates and Realistic Expectations
Success with TESA depends on several interconnected factors:
-
Underlying cause of azoospermia — obstructive causes generally have better sperm retrieval rates than non-obstructive causes.
-
Sperm retrieval vs. pregnancy success — retrieving viable sperm doesn't guarantee pregnancy; overall success also depends on egg quality, embryo development, and the IVF/ICSI process itself.
-
Partner's fertility profile — female age and ovarian reserve significantly influence overall treatment success.
A realistic, personalized conversation with your fertility team — rather than relying on general success rate statistics — gives the clearest picture for your specific case.
Risks and Recovery
TESA is considered a low-risk, minimally invasive procedure. Possible side effects include mild bruising, swelling, or discomfort at the needle site, which typically resolves within a few days. Rare risks include infection or hematoma (blood collection under the skin). Most men can return to normal, non-strenuous activity within 24–48 hours.
Why Choose Cutibless for TESA in Bangalore
At Cutibless, TESA is performed as part of a comprehensive Male Infertility and Andrology program designed to give men a clear, staged path toward biological fatherhood. If diagnostic clarity is needed before proceeding, we also offer Testicular Biopsy and Epididymis Biopsy to assess sperm production directly.
For men who've previously had a vasectomy and are weighing their options, we also perform Vas Recanalization (Vasectomy Reversal) as an alternative path to fertility, alongside advanced retrieval options like Micro-TESE and PESA. If a varicocele is a contributing factor to reduced sperm quality, Microscopic Varicocele Surgery may also be recommended as part of the broader treatment plan.

Frequently Asked Questions
Is TESA painful?
The procedure is performed under local anesthesia, so most men feel minimal discomfort during the aspiration itself, with mild soreness for a day or two afterward.
How is TESA different from a testicular biopsy?
Both involve accessing testicular tissue, but TESA is specifically focused on retrieving sperm for use in IVF/ICSI, while a testicular biopsy is primarily diagnostic, examining tissue to assess sperm production.
Can TESA be done on the same day as egg retrieval? Yes, TESA is often timed to coincide with the female partner's egg retrieval so fresh sperm can be used immediately, though frozen sperm from a prior TESA cycle can also be used.
What if no sperm is found during TESA? If TESA doesn't retrieve viable sperm, your fertility specialist may recommend a more advanced technique like Micro-TESE, which uses a surgical microscope to search more extensively through testicular tissue.
Does TESA affect testosterone production or sexual function? No. TESA targets a very small area of testicular tissue and does not affect hormone production, libido, or erectile function.
