Microsurgical Sperm Retrieval is an advanced set of procedures, such as mTESE (microdissection testicular sperm extraction) and MESA (Microsurgical Epididymal Sperm Aspiration), used to retrieve sperm from the testicles or epididymis for use in IVF/ICSI. This technique is reserved for men with Azoospermia (no sperm in the ejaculate) or severe Oligospermia.
Book an AppointmentThe procedures are performed by a specialist microsurgeon under high-powered magnification:
| Procedure | Indication & Advantage |
|---|---|
| mTESE | Used for non-obstructive azoospermia (sperm production failure). The microscope allows the surgeon to identify small, viable areas of sperm production, achieving a higher success rate while removing minimal tissue. |
| MESA | Used for obstructive azoospermia (sperm blockages). The procedure carefully aspirates sperm from the epididymis. |
| Anaesthesia | Procedures require general anaesthesia and are performed in a hospital setting. |
| Outcome | Retrieves sperm that can be frozen and used immediately for assisted conception. |
Dr. Kim’s specialisation in this field is critical, particularly because many non-microsurgical attempts fail, leading men prematurely to donor options.
Azoospermia means there are no sperm found in the ejaculate. It can be due to an obstruction (treatable) or a problem with sperm production (requires mTESE).
Successful retrieval provides the viable sperm necessary for IVF/ICSI. The subsequent success rate depends on the quality of the sperm and the female partner’s reproductive health, managed by your fertility specialist.
