Testicular Tissue Freezing

Preserve fertility with one simple procedure.

What is Testicular Tissue Freezing?

Testicular tissue freezing is a fertility preservation method for men who produce no sperm in their ejaculate – a condition known as azoospermia. This is often caused by an obstruction in the vas deferens, due to vasectomy, infection, or congenital absence.

In most cases, sperm are still being produced in the testes and can be retrieved for use in Intracytoplasmic Sperm Injection (ICSI).

Why Choose Testicular Tissue Freezing?

Previously, sperm had to be extracted from the testis on the day of the partner’s egg retrieval. Now, testicular tissue can be collected once, frozen, and used for multiple ICSI attempts, avoiding repeated procedures.

Benefits of Testicular Tissue Freezing

One-time procedure under local or general anesthesia
Minimally invasive (tiny incision, approximately 5 mm)
Lower risk of bleeding or infection
Flexible timing – procedure can be done months before treatment
Diagnostic value – tissue is examined for sperm presence
Allows time for counselling and planning if no sperm are found
Ideal for single men or those about to undergo chemotherapy, radiotherapy, or testicular surgery

How the Procedure Works

Initial tests: blood work and ultrasound
Day procedure: small biopsy under anesthesia
Sample analysis: one tissue section is tested for sperm
Freezing: remaining tissue sections are stored for future ICSI treatment

This fertility preservation technique is especially recommended for men diagnosed with azoospermia, those planning ICSI treatment in Mauritius, or men undergoing cancer treatment who wish to have biological children in the future.
