Sperm retrieval for in vitro fertilisation

1. What is it? Any common name for this procedure?

Sperm Retrieval refers to a group of surgical techniques used to collect sperm directly from the testicle or the epididymis (the tube where sperm is stored). This is performed when there is no sperm present in the ejaculate (Azoospermia) or when the patient cannot ejaculate.

The retrieved sperm is then used for ICSI (Intracytoplasmic Sperm Injection), where a single sperm is injected directly into an egg as part of the IVF process.

Common Names:

• Surgical Sperm Retrieval (SSR)
• Sperm Mapping
• Testicular Biopsy for Fertility

2. Common Indications: When is it Recommended?

Sperm retrieval is recommended for two main types of infertility:

• Obstructive Azoospermia (OA): Sperm is being produced but is blocked from exiting (e.g., due to a prior Vasectomy, absence of the Vas Deferens, or scarring from infections).
• Non-Obstructive Azoospermia (NOA): The testicles are producing very low levels of sperm that don't make it into the ejaculate (often due to hormonal issues or genetic factors).
• Ejaculatory Dysfunction: Conditions like retrograde ejaculation (semen going into the bladder) or spinal cord injuries.

3. List of Associated Risks and Conditions

• Testicular Discomfort: Mild aching or swelling for a few days after the procedure.
• Hematoma: A collection of blood (bruise) inside the scrotum.
• Hypogonadism: In rare cases of extensive tissue removal (micro-TESE), there is a slight risk of lowering testosterone levels.
• Failure to Retrieve: There is always a possibility that no viable sperm will be found, especially in cases of severe non-obstructive infertility.

4. List of Screening Tests and Assessment Tools

Before surgery, a "Male Fertility Evaluation" is performed to determine the best retrieval method.

5. Types of Sperm Retrieval Techniques

The choice of technique depends on whether the issue is a blockage or a production problem.

• PESA (Percutaneous Epididymal Sperm Aspiration): A fine needle is inserted into the epididymis to "vacuum" out sperm. Usually for blockages.
• TESA (Testicular Sperm Aspiration): A needle is inserted directly into the testicle to collect tissue and sperm.
• TESE (Testicular Sperm Extraction): A small incision is made to remove a piece of testicular tissue.
• Micro-TESE (Microsurgical TESE): An advanced procedure using a high-powered microscope to find "plump" tubules that are more likely to contain sperm. This is the Gold Standard for non-obstructive cases.

6. Am I Eligible for This Evaluation?

1. Azoospermia: You have had at least two semen analyses showing zero sperm.
2. Partner's IVF Cycle: You are planning or currently undergoing an IVF/ICSI cycle.
3. Post-Vasectomy: You have decided against a vasectomy reversal and prefer direct retrieval for IVF.
4. Health Clearance: You are healthy enough for minor surgery under local anesthesia or light sedation.

7. Days Required for Hospitalization

• Surgical Time: 20 to 60 minutes (Micro-TESE can take up to 2 hours).
• In-Hospital Stay: 0 Days. These are outpatient procedures. You usually go home within 2 hours of the procedure.
• Recovery: Most men can return to desk work in 2 days. Strenuous exercise and sexual activity should be avoided for 1 to 2 weeks.
• Hospitalization: 0 Days.

8. Benefits of Surgical Sperm Retrieval

• Enables Biological Fatherhood: Allows men with zero sperm count to have their own genetic children.
• High Success Rates in Obstructive Cases: For men with blockages, the chance of finding usable sperm is nearly 100%.
• Minimally Invasive: Most techniques use tiny needles or very small incisions that heal quickly.
• Cryopreservation: Retrieved sperm can often be frozen for use in future IVF cycles, avoiding the need for repeat surgery.
