Surgical Sperm Retrieval Procedures Explained

Everything You Need to Know About Surgical Sperm Retrieval Procedures

Male infertility affects many couples, but advances in reproductive medicine have provided hope. Surgical sperm retrieval procedures are an effective option for men who cannot produce enough sperm naturally or through non-surgical methods. At Iswarya Fertility Centre, these techniques allow couples to achieve biological parenthood even in complex cases.

Who Can Benefit from Surgical Sperm Retrieval?

Surgical sperm retrieval is recommended for men who:

Have had a vasectomy and want to father children.
Have non-obstructive azoospermia, where the testicles produce little or no sperm.
Experience ejaculatory dysfunction due to spinal cord injuries or other medical conditions.
Have failed sperm retrieval through non-surgical methods.

These procedures are tailored based on hormone levels, testicular size, and underlying causes of infertility.

Main Types of Surgical Sperm Retrieval Procedures

1. Testicular Sperm Aspiration (TESA)

TESA involves inserting a needle directly into the testicle to aspirate sperm. The sample is examined under a microscope by embryologists.

Best for: Obstructive and non-obstructive azoospermia.
Advantages: Minimally invasive, quick recovery, low risk of complications.
Success rate: 30–70%

2. Percutaneous Epididymal Sperm Aspiration (PESA)

PESA is the least invasive procedure, involving a fine needle inserted into the epididymis to extract sperm. The fluid is immediately checked for sperm count and motility.

Best for: Obstructive azoospermia.
Advantages: Simple, outpatient procedure, minimal discomfort.
Success rate: 70–90%

3. Testicular Sperm Extraction (TESE)

TESE is a surgical procedure where testicular tissue is removed to extract sperm. It is commonly used for men with spermatogenic failure, cancer treatment-related infertility, or obstructive azoospermia.

Advantages: Higher chance of sperm retrieval compared to TESA.
Considerations: More invasive, requires a small surgical incision.
Success rate: 30–60%

4. Microsurgical Testicular Sperm Extraction (Micro-TESE)

Micro-TESE is an advanced procedure where a surgical microscope is used to extract sperm from dilated seminiferous tubules. It is recommended for men with extremely low sperm production or severe non-obstructive azoospermia.

Best for: Complex cases with tissue damage or extremely low sperm counts.

Advantages: Maximizes the chance of finding viable sperm.

Considerations: Most invasive, requires a skilled surgeon and longer recovery.

Success rate: 50–65%
