TESA / TESE in Siliguri - Advanced Surgical Sperm Retrieval for Male Infertility
Navigating male factor infertility requires specialized diagnostic and surgical interventions. At Newlife Fertility Centre, our andrology and embryology teams utilize advanced reproductive techniques to assist men facing reproductive challenges in achieving biological fatherhood.
Surgical sperm retrieval methods - specifically Testicular Sperm Aspiration (TESA) and Testicular Sperm Extraction (TESE) - are specialized procedures designed to recover viable spermatozoa directly from the testes for patients diagnosed with azoospermia or severe impairment of sperm production.
These procedures are commonly integrated into comprehensive assisted reproductive treatment cycles, such as IVF combined with Intracytoplasmic Sperm Injection (ICSI), to address complex male factor considerations.
What is TESA / TESE?
TESA and TESE are minor surgical procedures utilized to retrieve sperm directly from testicular tissue when spermatozoa are absent in the ejaculate. Retrieved sperm samples are prepared in the laboratory and utilized in conjunction with Intracytoplasmic Sperm Injection (ICSI) - a technique where a single, carefully selected spermatozoon is injected directly into a mature egg to facilitate fertilization.
TESA (Testicular Sperm Aspiration)
TESA is a minimally invasive outpatient procedure performed under local anesthesia. A fine, precision needle is gently introduced into the testis to aspirate fluid and tissue containing spermatozoa.
TESE (Testicular Sperm Extraction)
TESE involves a minor surgical biopsy where a small incision is made to remove a tiny sample of testicular tissue under local or regional anesthesia. The tissue is examined under a microscope in the laboratory to isolate viable sperm, typically recommended in more complex cases of non-obstructive azoospermia.
Who May Be Considered for TESA / TESE in Siliguri?
Surgical sperm retrieval is primarily recommended for individuals where standard semen collection yields no spermatozoa or when specific clinical indications are present:
Azoospermia
The complete absence of spermatozoa in the ejaculate, which prevents standard semen-based sample collection.
Obstructive Azoospermia
A condition where sperm production within the testes is normal, but physical blockages - due to prior vasectomy, congenital absence of the vas deferens, or localized trauma - prevent sperm from entering the ejaculate.
Non-Obstructive Azoospermia
Impaired or severely diminished sperm production within the testes resulting from hormonal, genetic, or developmental factors.
Ejaculatory Dysfunction
Medical conditions such as spinal cord injuries, neurological disorders, severe diabetes, or retrograde ejaculation that prevent normal ejaculation.
Prior to Oncological Therapies
Sperm retrieval and cryopreservation prior to undergoing medical treatments - such as chemotherapy, radiotherapy, or pelvic surgeries - that may impact fertility.
Complex IVF / ICSI Protocols
When prior cycles or severe semen parameter limitations necessitate surgical retrieval to obtain viable spermatozoa for advanced assisted reproduction.
Prior to scheduling TESA or TESE, our specialists at New Life Fertility Centre perform comprehensive evaluations - including hormonal assays, genetic screening, scrotal ultrasound, and clinical assessments - to determine the most appropriate retrieval strategy.
How is TESA / TESE Performed at New Life Fertility Center Siliguri?
TESA Procedure Overview:
- Performed comfortably under local anesthesia.
- A fine needle is utilized to aspirate fluid containing sperm.
- Retrieved tissue is transferred immediately to the andrology laboratory for evaluation.
- Isolated spermatozoa are prepared for immediate use in ICSI or cryopreserved for subsequent cycles.
TESE Procedure Overview:
- Performed under local or monitored anesthesia.
- A precise, small incision allows access to the testicular tissue.
- Micro-dissection or tissue processing is performed in the lab to isolate viable sperm.
- The small incision is closed securely with minimal post-procedure discomfort.
Both procedures are structured as outpatient day-care surgeries, allowing patients to return home following a brief recovery observation.
Comparing TESA and TESE
| Feature | TESA | TESE |
|---|---|---|
| Invasiveness | Minimally invasive needle aspiration | Surgical tissue biopsy via small incision |
| Primary Indication | Obstructive azoospermia | Non-obstructive or complex male factor infertility |
| Anesthesia | Local anesthesia | Local or regional anesthesia |
| Recovery Period | 1 to 2 days | 3 to 5 days |
| Clinical Utility | Effective for patent tubular systems | Higher yield in focal spermatogenesis cases |
Your fertility specialist will recommend the most suitable retrieval method based on diagnostic findings and your individualized care plan.
Handling and Cryopreservation of Retrieved Sperm
Following retrieval, the specimen undergoes immediate laboratory processing to evaluate sperm concentration, motility, and viability. Depending on the treatment timeline, the retrieved sperm can be managed in several ways:
- Utilized fresh for ICSI if partner oocyte retrieval is synchronized.
- Cryopreserved (frozen) for future ICSI treatment cycles.
- Stored securely within our specialized andrology cryobank under stringent monitoring protocols.
Because ICSI requires only a single viable spermatozoon per mature egg, surgical retrieval can offer viable pathways even in cases of severe male factor infertility, allowing for flexible reproductive planning.

Frequently Asked Questions
Q. Is TESA / TESE a painful procedure?
No. Procedures are performed under local or regional anesthesia to ensure patient comfort. Post-procedure discomfort is typically mild and easily managed with prescribed care.
Q. Can I return home on the same day?
Yes. Both TESA and TESE are outpatient procedures, and patients are typically discharged after a brief post-operative monitoring period.
Q. Is surgically retrieved sperm suitable for ICSI?
Yes. When viable spermatozoa are isolated from retrieved testicular tissue, they are successfully utilized in ICSI procedures to achieve fertilization.
Q. What happens if no sperm is retrieved?
In rare instances where viable sperm cannot be identified, your fertility specialist will discuss alternative family-building options, such as donor sperm, during a supportive follow-up consultation.
Q. Can surgical sperm retrieval be repeated if necessary?
Yes. Depending on the underlying testicular condition and clinical goals, retrieval procedures can often be safely repeated when indicated.
