Infertility affects both men and women, and in nearly 40% of cases, male factors contribute significantly. One of the most challenging male infertility conditions is azoospermia – the complete absence of sperm in the ejaculate.
For couples where the male partner has azoospermia, natural conception or even standard IVF is not possible. But with the advancement of reproductive medicine, Surgical Sperm Retrieval (SSR) offers a breakthrough solution. By retrieving sperm directly from the testicles or epididymis through minor surgical procedures, even men with azoospermia can become biological fathers.
At Karnic Clinic, we specialize in advanced sperm retrieval techniques including PESA, TESA, and TESE, followed by ICSI (Intracytoplasmic Sperm Injection), giving couples the best chance of achieving pregnancy.
What is Surgical Sperm Retrieval (SSR)?
Surgical Sperm Retrieval refers to a group of minimally invasive surgical procedures used to collect sperm directly from the male reproductive system. It is especially used for:
- Obstructive Azoospermia – when sperm production is normal, but a blockage prevents sperm from reaching the ejaculate (e.g., vasectomy, congenital absence of vas deferens).
- Non-Obstructive Azoospermia – when sperm production is very low, and sperm are present only in small numbers inside the testes.
The retrieved sperm are not enough for natural conception but are sufficient for ICSI, where a single sperm is injected into an egg.
Types of Surgical Sperm Retrieval Techniques
At Karnic Clinic, we offer the following procedures depending on the cause of azoospermia:
1. PESA (Percutaneous Epididymal Sperm Aspiration)
- A fine needle is inserted through the skin of the scrotum into the epididymis (a small structure where sperm mature and are stored).
- Fluid containing sperm is aspirated and examined under a microscope.
- Best suited for obstructive azoospermia, where sperm production is normal but cannot reach the ejaculate due to a blockage.
- Advantages: Simple, quick, minimal discomfort, and does not require stitches.
2. TESA (Testicular Sperm Aspiration)
- A needle is inserted directly into the testes, and small amounts of tissue and fluid are aspirated.
- The sample is analyzed under a microscope to find sperm.
- Suitable for both obstructive and non-obstructive azoospermia.
- Advantage: Less invasive, can be performed under local anesthesia, and often sufficient for ICSI.
3. TESE (Testicular Sperm Extraction)
- A small incision is made in the testes, and a tiny piece of testicular tissue is removed.
- The tissue is examined in the lab to search for live sperm.
- TESE is often used when PESA or TESA do not yield sperm.
- Advantage: Higher likelihood of finding sperm in cases of very low sperm production.
When is Surgical Sperm Retrieval Needed?
SSR is recommended in cases such as:
- Azoospermia (no sperm in semen)
- Blockage of the sperm ducts (due to vasectomy, infection, or congenital causes)
- Failed vasectomy reversal
- Congenital absence of vas deferens (seen in some men with cystic fibrosis gene mutation)
- Testicular failure with focal sperm production
- Couples where IVF has failed due to severe male factor infertility
Benefits of Surgical Sperm Retrieval
✔Allows biological parenthood even in azoospermia
✔Minimally invasive procedures with quick recovery
✔Can be combined with ICSI for high fertilization rates
✔Avoids the need for donor sperm in many cases
✔Provides long-term solutions – retrieved sperm can also be frozen for future IVF cycles

Frequently Asked Questions (FAQs)
Will sperm always be found with SSR?
Not always. In some severe cases of non-obstructive azoospermia, sperm may not be present. But advanced techniques like TESE maximize the chances.
Is SSR painful?
No. The procedures are minimally invasive and done under anesthesia. Mild discomfort may occur afterward but subsides quickly.
Can retrieved sperm be frozen?
Yes. Sperm obtained via SSR can be cryopreserved for future ICSI cycles.
Do men need hospitalization for SSR?
No. These are outpatient/day-care procedures, and patients can go home the same day.
Is donor sperm still needed after SSR?
In most cases, SSR provides viable sperm, avoiding the need for donor sperm. Donor sperm is considered only if SSR fails.
